What’s going on with food prices these days? You may have noticed that your food bill is dramatically higher than it was a few years ago. And it’s not just you. Food is more expensive pretty much everywhere, and the jump has been staggering.

According to economists (who, it seems to me, are a lot better at explaining the past than predicting the future), this massive food inflation is actually caused by a perfect storm of rising demand and lower supply — both intensified by several calamities (like droughts, floods, wars, and knock-on effects of the COVID-19 pandemic) — as well as rising costs for fuel and fertilizer.

For perspective, food prices have typically been rising by about 2% a year for a long time. But from 2021 to 2022, they went up by an average of 11%. And while things seem to have calmed down a bit since then, it’s still easy to get sticker shock any time you visit a cash register.

Even if you’re not paying more outright, you might be paying more in subtle ways. The food industry has recently implemented a tactic known as “shrinkflation,” whereby they offer the same product for the same price — in a smaller quantity, thus avoiding the appearance of higher prices. (“Hey, this is one expensive cornflake!”)

So why exactly have food prices gone up so much? Why do some foods always seem to cost more (or less) than others? And what can you, as a consumer, do about it?

What Influences Food Prices

Did I mention that I’m not an economist? That might be good news here because I’m going to try to simplify the issue of food pricing. There are a few major factors that always influence food pricing. These include how much it costs to produce the food (including the cost of labor for everyone involved in growing and processing it), the cost of transportation and distribution, good old supply and demand, and global trade policies.

Why have food prices gone up so much in the last few years? Three factors stand out, in particular: the lingering effects of the COVID-19 pandemic, the war in Ukraine, and the intensifying climate crisis.

The COVID-19 Pandemic

Starting in 2020, the pandemic disrupted nearly every link in the food supply chain. The food processing sector was hit particularly hard, with COVID-19 outbreaks racing through the workforce, due to many people working in close, inadequately ventilated quarters. And the increase in worker turnover, in addition to new COVID protocols, further increased food production costs.

The same labor shortages affected the shipping industry, causing delays and increasing competition for limited shipping space. This led to rising transportation costs. It also increased the price of labor: In order to attract workers, companies had to increase wages, a cost they largely passed directly on to consumers.

As many people shifted their food spending from restaurants to grocery stores, suppliers could not keep up with the change in demand, resulting in massive food waste that effectively decreased supply.

And while 2020 is in the rearview mirror, there’s a funny thing about economics. When prices go up, they rarely come down again. So in some ways, we’re still feeling the effects of the price increases that started in 2020. And now, some additional factors have intensified the situation.

The War in Ukraine

Before the war, Russia and Ukraine were among the largest wheat producers in the world, together accounting for 30% of all exports — and a staggering 12% of all agricultural calories traded on earth. Both production and export have dropped dramatically due to the war.

Russia set up blockades of Ukrainian food exports in the Black Sea, stranding food in ports and creating global shortages. Western countries responded with sanctions against Russian grain exports, intensifying those shortages.

In addition to embargoes on food, the West has also implemented partial bans on Russian exports. These have included oil and gas, which have increased the energy costs associated with food production around the world.

Another blockaded product is fertilizer. As Russia is a major exporter of synthetic fertilizers, accounting for almost 30% of all exports globally, fertilizer prices have also been soaring — impacting farmers and, therefore, food prices.

Increasing Climate Chaos and Disasters

As temperatures continue to rise, crops are sustaining damage from excess heat. And as precipitation patterns change, droughts and flooding (sometimes alternating in the same place) also prevent crops from thriving. This can harm crops by eroding soil, depleting soil nutrients, and increasing runoff.

No farmer wants to try to coax crops out of the ground in conditions of extreme and prolonged drought. As more and more of the arable land on Earth suffers under multiyear drought, farmers are increasingly relying on groundwater, which they’re depleting at an alarming rate.

Additionally, rising temperatures increase pest populations and sometimes allow new pests to take up residence in regions that had previously been inhospitable for them. Temperature shifts can also cause a mismatch in pollination cycles, so the “good” bugs can’t do their jobs — leading to low pollination rates or delayed pollination.

One more disastrous effect of a warming planet is the danger to agricultural workers. More and more of them are suffering from the effects of extreme heat as they toil in parched fields. The National Institutes of Health tells us that farmworkers are 35 times more likely to die of heat exposure than workers in other industries. As conditions become less hospitable, it can be harder for farm owners to find the skilled laborers they need to get their fields planted and harvested. And dynamics in US immigration policy have contributed to a shortage of these workers.

As the planet continues to overheat, and as groundwater gets depleted and droughts and floods intensify, food prices are expected to continue to increase in the coming decades.

Why Do Some Foods Always Cost More (or Less)?

Governmental policies cause some foods to be more expensive than they would be otherwise — while others are made artificially cheaper. To see this in action, let’s look at a category of foods whose price is inflated (organic foods) and another whose price is deflated (grains and the products derived from grains).

Organic and Healthy Food Costs

Organic foods are more expensive than their “conventional” counterparts for several reasons. For one, organic food typically costs more to produce because the process is more labor-intensive than large-scale industrial agricultural methods.

Supply and demand play a role here as well. There’s a much smaller supply of organic food than nonorganic, even though demand for organic foods has more than doubled in the past 10 years. While this demand has caught the attention of some farmers who have decided to convert part or all of their operations to organic methods, this process takes time. In the meanwhile, prices continue to rise as demand grows, but supply lags.

There’s also a policy choice that makes organic food more expensive, which is that organic certification is costly, and getting that certification can be time-consuming. Organic farmers must keep extensive records and pay for organic certification, while farms that use synthetic pesticides don’t have to do either.

Another reason for organic’s higher prices has to do with the concept of “externalities” — that is, costs that arguably should be included in the market price but aren’t.

For example, what are the true costs of topsoil erosion, pesticide exposure for farmworkers and consumers, water and air pollution, or of the routine use of antibiotics in modern factory farms? If these were factored in, we might find that organic food would cost less, not more, than its conventional counterparts.

The fact is that organically grown foods tend to be better for environmental protection and carbon sequestration, deliver higher standards for animal welfare, and contribute to a safer and healthier food supply.

But consumers still have to pay more, and sometimes a lot more, to purchase foods that are grown organically.

Despite this, there are still some compelling advantages to go organic if you can afford to do so. And if you can’t, then you might want to soak your produce in a dab of baking soda to help rid it of pesticide exposure (for our article on what works best, click here).

Government Subsidies

The US government provides agricultural subsidies — monetary payments and other types of support — to farmers or agribusinesses. This ensures that farmers receive a minimum price for their crops while also incentivizing overproduction and inflated production costs. That way, subsidized foods and products made from them appear cheaper than nonsubsidized foods.

Generally, only the largest producers can take advantage of farm subsidies. According to a report from the Environmental Working Group, between 1995 and 2021, the top 10% of all US farm subsidy recipients received almost 80% of all subsidies, while the bottom 80% got less than 10%.

The five major “program” commodities are corn, soybeans, wheat, cotton, and rice.

Most soybeans and corn are produced by massive monocrop farms rather than small family enterprises. A lot of this subsidized corn and soy is fed to livestock, which artificially lowers the price of animal-derived foods produced on factory farms. All told, the US federal government spends $38 billion every year subsidizing the meat and dairy industries. Without these subsidies, a pound of hamburger meat could cost $30, rather than the $5 price seen today. But the true cost plays out in its impact on our health, animals, and the environment — and in the form of taxes and expansion of the national debt.

Is it better in Europe? Well, in many ways, it’s not. According to a 2019 report from Greenpeace, nearly one-fifth of the EU’s entire budget goes to subsidizing the livestock industry.

In effect, these subsidies consistently decrease the price of things like factory-farmed meat, high-fructose corn syrup, white bread, and many of the additives in our food supply — creating a marketplace distortion that makes fruits, vegetables, nuts, seeds, and other healthy staples more expensive in comparison.

To my eyes, it’s a bit like we’re all being fined for wearing our seatbelts. If we want to do the safer and more responsible thing, we have to pay extra.

What You Can Do About Rising Food Prices

If you’re feeling the pinch of rising food prices yourself, there are several strategies that can help you stay within your budget without sacrificing your family’s health.

Make a budget and shop from a list to avoid making impulse purchases while at the store. Prioritize nutrient-dense foods over calorie-dense ones. The latter may seem cheaper by the pound or the calorie, but in terms of what foods can do for you (or to you), good nutrition is more economical than impaired functioning or chronic disease. And buy and cook in bulk to save money and time.

Try to shop locally if you can to avoid incentivizing costly supply chains. If you’re in the US and use SNAP benefits, keep in mind that you can use them to shop for fresh produce at many farmers markets.

Also, buy organic when you can. If you are in a position financially where you can afford to spend more, you can “vote with your dollars” (or euros or pounds or rupees) to make the system fairer and more accessible to everyone. But if you can’t afford the organic price premium, then aim for non-GMO produce items and wash them thoroughly to reduce your pesticide exposure as much as possible.

If you have to choose which fruits and veggies to buy organic, check out the Environmental Working Group’s Dirty Dozen and Clean 15. Choose organic members of the Dirty Dozen club, and don’t sweat nonorganic Clean 15 items.

Frozen fruits and vegetables can sometimes be more affordable than fresh ones, and they contain abundant nutrition.

And reducing your consumption of animal products can not only help feed the world’s population because we aren’t cycling our crops through animals (a process that wastes at least 9 out of every 10 calories, depending on the crop and the animal eating it), but it can also lead to reductions in costly greenhouse gas emissions, too. Plus, beans tend to be a lot less costly than beef (to animals, the environment, and your wallet, too).

Food Pricing Is Complex, But Healthy Eating Shouldn’t Be

The recent surge in food prices has highlighted the intricate web of factors influencing the cost of our food. From labor shortages and technology costs to climate change and war, the forces at play are vast and interconnected.

But there are ways to navigate these challenging times. By adopting conscious strategies, we can mitigate the impact of rising food prices on our wallets and well-being. Through awareness and mindful decision-making, we can not only do right for our health, but we can also contribute to a more healthy, sustainable, and equitable food system.

They not only protect plants from disease and sun damage, but when you eat those plants, you’re getting similar benefits. So what does the evidence say about how polyphenols can fight chronic disease, and what the best sources are?

Imagine you’re a plant. You can’t run away from the insects trying to eat you alive. You can’t wash off bacteria, viruses, or fungi before they can infect you. And you can’t put on SPF 50 sunscreen or a big floppy hat to protect yourself from the sun’s harmful ultraviolet rays.

What do you do to stay alive and thrive in the face of all these challenges? If you answered “synthesize polyphenols,” then congratulations! You’ve just won this round of “Are You as Smart as a Plant?”

Polyphenols are a class of compounds (a huge class, actually, made up of at least 8,000 different ones that we know of) that are in a wide variety of plant foods. You may have heard of some of them, like resveratrol (found in grapes and red wine) and EGCG (featured in green tea).

Plants produce them as protection from various threats, including disease and sun damage. And animals who consume those plants can also benefit from polyphenols in similar ways.

As industrialized societies struggle to contain multiple epidemics of chronic disease, many medical experts and researchers are now pointing to polyphenols (and other nutrients found in whole, minimally processed plant foods) as powerful allies in preventing and treating a variety of chronic conditions.

So in this article, we’ll explore the world of polyphenols, including how they work in your body, their health benefits, and whether you should get them from food or supplements.

What Are Polyphenols?

Polyphenols are natural compounds found in various plants. Researchers consider polyphenols to be kind of “bonus” compounds, or in their jargon, “secondary metabolites.” This means they’re not directly involved in the growth, development, or reproduction of a plant.

Plants produce polyphenols as a defense mechanism against ultraviolet radiation and aggression from pathogens. But they aren’t purely defensive; they’re also deployed to attract pollinators.

From our perspective, polyphenols play a significant role in the flavors and health benefits that many plant foods offer. They can change the way plants taste, and determine their colors and aromas.

Polyphenols are also antioxidants, so their presence can keep plant foods from rotting (a trick known as “oxidative stability”). They also can help prevent oxidative stress in your body after you consume them, which can help stave off many types of disease.

There are several subfamilies of polyphenols, including flavonoids, phenolic acids, and lignans. In addition to resveratrol and EGCG mentioned above, another well-studied polyphenol is curcumin, found in turmeric root and powder.

What Are the Health Benefits of Polyphenols?

The “poly” in polyphenol means that all compounds in this family have multiple phenolic hydroxyl groups — but could just as easily refer to their ability to prevent and treat multiple health conditions.

Polyphenols and Cancer Prevention

Both test-tube and animal studies suggest that polyphenols can help prevent the initiation and progression of several cancers. They do this via a number of mechanisms, including inhibiting the proliferation and spread of cancer cells, suppressing tumor growth, preventing the formation of new blood vessels, and fighting inflammation.

Different classes of polyphenols exhibit different anticancer properties. For example, flavonoids, including quercetin and kaempferol, can inhibit cancer cell growth and induce cancer cell death. Resveratrol suppresses tumor growth, inhibiting metastasis and reducing angiogenesis. And curcumin, derived from turmeric, is multitalented; it’s anti-inflammatory, antioxidant, apoptotic, antiangiogenic — and a bunch of other words that don’t begin with A.

Many forms of polyphenols are also known to influence critical signaling pathways that are integral to the initiation, advancement, and spread of cancer.

And polyphenols aren’t just cancer fighters on their own; they’re also team players. Researchers have found that polyphenol combinations are more powerful than the effects of each one individually. For example, a mixture containing quercetin, curcumin, green tea, Cruciferex (a proprietary blend of polyphenols found in cruciferous vegetables), and resveratrol significantly inhibited the growth of a particular cancer of the head and neck.

Polyphenols and Heart Health

Polyphenols can also protect your heart in a bunch of different ways. They reduce cardiac inflammation and oxidative stress, support cell mitochondria in doing their job properly, and increase survival signaling (the ways cells talk to each other when they encounter a potential threat).

Some polyphenols have also been found to reduce the formation of blood clots, which decreases the risk of heart attacks and strokes. And the flavonoid family of polyphenols promotes the dilation of blood vessels, which helps lower blood pressure and improve blood flow — both of which help with cardiovascular health.

Polyphenols can also improve your cholesterol profile — specifically, lowering LDL and increasing HDL cholesterol levels, thereby reducing the risk of atherosclerosis.

Some polyphenols are not easily absorbed by your small intestine, but it turns out that these polyphenols can be metabolized by the microbes in your gut into compounds that contribute to cardiovascular health.

Impressed by these myriad beneficial mechanisms, some researchers are now studying therapeutic protocols for using polyphenols in medicine to prevent and treat cardiovascular disease.

Polyphenols and Diabetes

One of the most dangerous consequences of diabetes can be vascular disorders, where persistent high blood sugar levels cause damage to blood vessels through inflammation, oxidation, and cell death. Polyphenols can combat all three mechanisms. And scientists are exploring how to use them to modulate the expression of the genes involved in the development of vascular conditions.

Human and animal studies (our views on the use of animals in medical research can be found here) show that polyphenols can lower high blood sugar levels and enhance the body’s ability to secrete insulin quickly and respond to it effectively.

It appears polyphenols accomplish this via several mechanisms. They slow down how quickly your body absorbs sugar from the food you eat. And they encourage your pancreas to produce more insulin in response to carbohydrate consumption. They also regulate how much glycogen the liver releases into your blood in the form of sugar.

If all that wasn’t enough, polyphenols also help insulin receptors work more efficiently and help tissues absorb more sugar than they would otherwise.

Polyphenols also fight diabetes by helping to protect pancreas cells that produce insulin from damage due to high glucose levels. They also promote the growth of these cells and slow down their death.

Polyphenols and Osteoporosis Benefits

As you age, you lose bone mass — that’s natural. But your diet and lifestyle can significantly influence the rate at which that happens. In some people, the process accelerates due to oxidative stress messing with the living tissues in bone: the osteoblasts and osteoclasts that build and break down bone, respectively.

Since polyphenols are such powerful antioxidants, researchers theorized that eating berries (one of the richest food sources of the compounds) could help reduce bone loss due to stress and aging. And they might have been on to something because several studies have now shown that people who eat a lot of berries also have higher bone mass. Since the standard pharmaceutical treatments for osteoporosis have a high rate of serious side effects, there’s a lot to be gained by exploring how eating polyphenol-rich foods can help prevent or slow bone loss.

In addition to oxidative damage, it appears that bone loss can also be caused by inflammation. A 2019 literature review found evidence that polyphenol-containing foods like fruits, vegetables, tea, and soy may combat osteoporosis by reducing inflammation, thus allowing the body’s bone remodeling process to proceed without hindrance.

A 2023 study out of Korea also found concrete evidence for the link between high polyphenol intake and protection from osteoporosis. Researchers gave bone density tests and food intake questionnaires to 4,600 women and followed up with them for an average of five years. They found that the postmenopausal women who reported eating the most phytochemical-rich foods (i.e., those high in polyphenols) had a 16% lower risk of developing osteoporosis than those who ate the least.

Polyphenols and Brain Health

One of your body’s most important functions goes by the strange name autophagy, which literally means “eating oneself.” Instead of visualizing someone chomping on their own arm, however, think of your tissues constantly absorbing and discarding malfunctioning cells, proteins, and other bits and bobs that are no longer doing their jobs. This process in the brain is key in protecting you from neurodegenerative diseases such as Parkinson’s, MS, ALS, Huntington’s, Alzheimer’s, and other types of dementia.

Research shows that polyphenols support the brain’s clean-up process by removing misfolded proteins. They also reduce brain inflammation and stress, helping protect the brain from damage that can lead to neurodegenerative conditions.

Polyphenols are especially suited to supporting your cognitive health for several reasons. First, unlike many other nutrients, they can easily pass into your brain from your bloodstream (crossing that very finicky blood-brain barrier). Second, they help to remove harmful substances known as reactive oxygen species that can damage your brain cells. Third, they can capture and neutralize certain metal ions, such as copper and iron, that could be harmful to your brain in high concentrations.

But wait — there’s more! Polyphenols have another special brain ability: They can increase the amount of neurotrophic factors in your brain that promote the health and growth of your nerve cells. By attaching themselves to the receptors of these neurotrophic factors on the surface of nerve cells, polyphenols enhance the cells’ abilities to adapt, survive, multiply, and grow. It appears, in fact, that polyphenols can not only protect your brain from degeneration but may even support learning, memory, and other cognitive abilities.

Is There an RDA for Polyphenols?

Given how awesome polyphenols are, you might think that government bodies tasked with setting nutritional standards would have come up with a recommended daily allowance (RDA). But no such standard exists in the US because the compounds aren’t considered “essential” nutrients — that is, there aren’t any diseases specifically caused by a deficit, the way insufficient vitamin C leads to scurvy and not enough B1 inevitably produces beriberi.

Instead, not getting enough polyphenols can shorten a lifespan by making a person more likely to develop one of the chronic diseases mentioned above. For example, a 2013 study found that people who consumed more than 650 milligrams of polyphenols per day had a 30% lower chance of dying in any given year compared with people who got less than 500 milligrams per day.

So instead of a numerical RDA, the quasi-governmental Food and Nutrition Board of the Institute of Medicine recommends five fruits and/or vegetables a day, which theoretically would give you a significant amount of polyphenols. And if you “eat the rainbow” pretty much every day — that is, consume foods of many different colors (and no, Skittles don’t count) — you’ll also therefore get a wide range of polyphenols.

What Foods Are Rich in Polyphenols?

What Influences Polyphenol Amounts?

Unfortunately, you can’t simply look up a food’s polyphenol content in an online database and know exactly how much you’ll get when you eat that food. And even if you could, there are various factors that can influence how much you actually absorb.

Polyphenol Bioavailability

On the whole, polyphenols tend to have low bioavailability, which means your body can absorb and use only a small percentage of what you swallow.

The exact conversion ratio is based on many factors, including the health and makeup of your gut microflora. Since your microbiome can change on a constant basis, depending on what you feed it, how much of the polyphenols in your food you can actually get into your cells may also vary widely from day to day.

Also, the different polyphenols differ greatly in how bioavailable they are. The most abundant dietary polyphenols typically have lower absorption rates than less common ones.

Food Handling Impact

How plant-based foods are processed, stored, and cooked also strongly influences their polyphenol content.

If you remove the peels and hulls of certain foods, you can lower their polyphenol content. On the other hand, macerating (such as in a blender or food processor) some foods can increase their polyphenol content.

When it comes to food storage, the cold storage of apples, pears, and onions appears to maintain high polyphenol levels. But when cut fruits turn brown, which tends to happen if they are exposed to air, they begin to lose polyphenols.

Many foods lose polyphenol levels with time. For example, in wheat flour, concentrations of polyphenols drop by about 70% after six months. But black tea actually increases its polyphenol content after some oxidation.

Some polyphenol levels also increase with cooking, while others decrease — it depends on the food, the particular polyphenolic compound, and the cooking method. For example, onions and tomatoes lose between 75% and 80% of their initial quercetin content after boiling for 15 min, and 65% after cooking in a microwave oven.

So Should You Take Polyphenol Supplements?

A limited amount of research has indicated that people may possibly see benefits from polyphenol supplements. For example, athletes who were experiencing physiological stress were given polyphenol supplements, and they experienced some benefits in performance and recovery.

But the evidence is a bit murky: Many researchers don’t use pure polyphenols or mixtures, but add in other antioxidants — so it’s hard to know how much of the benefit is coming from the polyphenols, the other active ingredients, or some synergistic interaction of multiple elements.

There’s also not a lot of safety data available about these supplements. And as polyphenol marketing gives these compounds their place in the sun, some manufacturers are taking advantage of their popularity to create mega-dose formulations that have never been tested for safety or efficacy.

Because research on the benefits of polyphenols typically uses amounts much higher than those commonly found in human diets, we just don’t know the levels at which they are safe and beneficial for human consumption.

Some supplements (including those containing polyphenols) could cause liver damage in high doses, and may also block the absorption of nonheme iron, which is an essential nutrient.

Perhaps the best argument against supplementation is that it’s probably completely unnecessary for most people, as polyphenols are abundantly available in a wide variety of fresh and healthful foods.

Plus, just like every other plant-based antioxidant and phytonutrient, polyphenols work better in harmony with other nutrients that naturally occur in food. And when you consume whole plant-based foods, you also get the benefit of fiber and other health-promoting micronutrients.

In general, most people are better off getting their nutrition from food rather than from supplements, and there’s no reason to think that polyphenols are an exception.

Polyphenol Recipes

From bitter to salty, from sweet to tart, polyphenols are in abundance in many of your favorite plant-based foods. These delicious and nourishing polyphenol recipes are a great way to experiment with and incorporate them into your daily meal routine.

1. Banana Tahini Coffee Smoothie

Banana Tahini Coffee Smoothie

Coffee is a plentiful source of polyphenols as it contains chlorogenic acids, which fight free radicals and prevent oxidative stress damage, making it a potent antioxidant-rich ingredient. Not only does it give you a burst of energy — you get a powerful health boost, too! Together with creamy banana, nutty tahini, nutrient-rich cauliflower, and sweet spices, this Banana Tahini Coffee Smoothie is an easy-peasy and ultra-creamy way to enjoy polyphenols.

2. Apple Walnut Sage Dressing

Apple Walnut Sage Dressing

Apples have an abundance of polyphenols, more specifically anthocyanins, flavanols (catechins), flavonols (quercetin, rutin), chlorogenic and caffeic acids, and dihydrochalcones, which can help to reduce inflammation, support your immune system, and even help with seasonal allergies! We don’t think you’ll need any more convincing, but this creamy Apple Walnut Sage Dressing is an inflammation-fighting, health-promoting, and deliciously sweet and savory sauce that is the perfect polyphenol-rich addition to your favorite summer or fall salad.

3. The Shine Brightly Salad

Shine Brightly Salad

We love The Shine Brightly Salad for many reasons. And the addition of sweet and juicy blueberries is a major factor! Blueberries are loaded with anthocyanins, resveratrol, and flavonols (quercetin), which are all under the umbrella of polyphenols. You’ll also get a hefty dose of health-promoting spinach, red onion, sunflower seeds, and lemon juice. With so many colorful plant foods combined, you know you’ll be getting a wide variety of phytochemicals, antioxidants, and other polyphenols that will keep your body in tip-top shape — and shining brightly from the inside out!

Eat More Plants to Reap the Benefits of Polyphenols

From fending off cancer and heart disease to supporting healthy blood sugar levels and bone density, polyphenols are like real superheroes of our dietary choices, working tirelessly to safeguard our well-being. These compounds are readily available in a wide array of whole foods.

While some individuals may find benefit from polyphenol supplements, on the whole, the safety and efficacy of high-dose polyphenol supplements remain unclear. So it’s probably best to get your polyphenols from food. And let your plate be a canvas of color and flavor, celebrating the goodness that polyphenols have to offer.

Without it, though, you can’t survive. And both too little, and especially too much, can damage your heart, brain, bones, skin, and immune system. So how much do you really need? What are the best sources? How easy is it to get enough on a plant-based diet? And how can you avoid copper toxicity?

The post Dietary Copper: How Much Copper Should You Get and the Best Sources of Copper appeared first on Food Revolution Network.

In 1982, the US Mint radically changed the makeup of the penny, from 95% copper all the way down to 2.5%. The reason? Copper had become so expensive that the metal in the coins was worth more than the face value, leading people to hoard them in the hopes of turning a profit.

Prices for copper rose in the 1970s largely due to the electronics revolution. Copper is a great conductor of electricity. So as the need for wiring and components increased, global demand did, too.

Copper’s properties also make it not just valuable but indispensable for human health. It doesn’t get the same press as other minerals, such as calcium and iron. But it serves many crucial functions in the body.

In this article, we’ll explore why copper is necessary for bodily functions ranging from immune support to antiaging properties to brain protection. We’ll discuss the potential risks of not getting enough copper, and whether that’s a concern (especially for plant-based eaters), as well as the very real dangers of getting too much copper.

What Is Copper?

Copper is an essential trace mineral found in every tissue of your body. Like other minerals, your body doesn’t make its own; you need to get it from food. But compared to many other essential minerals, you don’t need a lot for optimal functioning.

Copper is a very busy do-gooder in your body, lending a hand all over the place. It’s a cofactor (a nonprotein molecule that supports a biochemical reaction) for several enzymes known as cuproenzymes (“kupros” is Greek for copper, so named because the island of Cyprus was famous for its rich copper deposits). These enzymes are involved in the production of energy, neurological signaling, and the making of connective tissue.

Copper helps your body form collagen and assists in iron absorption. It also acts as an antioxidant. The main defense against oxidative stress actually involves copper-based compounds called superoxide dismutases (SODs for short). SODs help convert superoxide radicals into less harmful molecules like oxygen and hydrogen peroxide.

Copper is also involved in the formation of new blood vessels. Plus, it helps balance various neurohormones, regulates gene expression, supports brain development, influences skin pigmentation, and maintains the functioning of the immune system. That’s one busy mineral!

How the Right Amount of Copper Benefits Your Health

Copper is essential for many bodily processes but harmful in both deficiency and excess. (Or as Goldilocks might say, “Not too little and not too much, but just right.”) Maintaining appropriate copper levels is important for overall well-being. And it’s particularly important for the health and functioning of your brain, bones and joints, heart, arteries, skin, and immune system.

Let’s look at some of the ways that researchers study copper in regard to health.

Copper and Heart Health

Proteins containing copper are essential for protecting your cardiovascular system from stroke and the damage it can cause. When the body doesn’t manage copper levels properly, it can lead to heart problems, including enlargement, heart failure, coronary artery disease, and a type of heart disease related to diabetes.

But for most people, too much copper is a more likely problem than not getting enough. A 2015 study compared copper levels in 334 people, some of whom had healthy arterial function and some with varying degrees of atherosclerosis (arterial hardening and blockages). Researchers found higher blood levels of copper in the patients with atherosclerosis. And the more severe the condition, the higher the levels of copper.

Because of the study design, we can’t say whether the high copper levels caused the atherosclerosis or if it was the other way around. (Or, for that matter, if both stem from something else.)

Copper and Brain Health

The right amount of copper is also necessary for brain development and function. Diseases that affect brain copper levels, such as Menkes disease (not enough copper) and Wilson disease (too much copper), affect the functioning of neurotransmitters called catecholamines. They play a role in various brain functions, such as regulating mood, motivation, attention, and stress response. And they’re involved in transmitting signals between neurons and can affect cognition and behavior.

Elevated copper levels may also play a role in the development of Alzheimer’s disease. Studies have shown high levels of copper can affect the functioning of neurons in important areas of the brain, such as the hippocampus and cerebral cortex. This can lead to problems with memory, critical thinking, and motor skills.

Researchers have also discovered a connection between copper and the formation of amyloid beta plaques, which are a hallmark of Alzheimer’s disease. As copper levels increase, it can speed up the formation of these plaques, contributing to further damage in the brain.

Copper and Bone Health

Too much or too little copper is also a problem for your bones and joints. Copper compounds are important cofactors for an enzyme that makes bone matrix (basically, the stuff that makes up your bones). And nearly two-thirds of the copper in your body is stored in muscles and bones.

In 2014, researchers looked at 50 adults who had severe tooth wear (that means their teeth were worn down, not that their teeth wore high-necked cardigans and ankle-length skirts). They found lower copper levels in their tooth enamel, as well as lower bone mineral density in the spine, which is a predictor of osteoporosis.

A 2018 study measured copper levels in participants’ blood and also looked at several aspects of bone health, including bone mineral density and whether they had fractured any bones. Researchers found that people with lower levels of copper had lower bone mineral density in certain areas of the hip compared to those with slightly higher levels of copper.

They also found that those with very high levels of copper in their blood had a higher risk of experiencing fractures compared to those with slightly lower levels. So again, copper adheres to the Goldilocks principle.

Copper and Skin Health

It’s time to introduce you to a very special substance in your blood: glycyl-L-histidyl-L-lysine. That’s a mouthful, so we’ll follow the scientists in calling it GHK.

GHK levels are highest when you’re young, around 20 years old, but decrease as you get older. By the time you’re 60 years old, the levels drop significantly.

GHK has a special attraction to copper, and when they come together, they form something called GHK-Cu. GHK-Cu can help rejuvenate your skin by promoting the growth of new skin cells and speeding up the healing process. It has powerful antioxidant properties, which means it helps protect your skin from the sun and other oxidative damage. And it can also reduce inflammation in the skin, which can help prevent and smooth out wrinkles.

Did you know your skin can absorb copper? Studies show that there’s a low risk of adverse reactions from skin absorption of copper. And several placebo-controlled clinical trials have shown that sleeping on pillowcases impregnated with copper oxide can actually reduce the depth of facial wrinkles and improve overall skin health.

A 2020 study took small skin grafts and exposed them to these fabrics. The researchers found that they continuously released copper ions that were absorbed through the skin, which increased the production of some skin proteins, stabilized the dermal layer, and reduced aging and damage.

Copper and the Immune System

Copper is also required for the formation and activity of neutrophils, a type of white blood cell that’s a key component of the immune system. Their main role is to defend the body against infections caused by bacteria and fungi.

But there’s a downside to copper’s ability to support immunity: There’s an association between excess copper levels and increased immunity of cancerous tumors to treatment. So how difficult is it to get the right amount of copper for good health?

How Much Copper Do You Need?

Since copper is a trace nutrient, only a small amount is necessary daily. And only a small amount is stored in the body. Whereas iron or calcium requirements are in milligrams per day (mg/day), copper needs are in micrograms per day (mcg/day). A microgram is one-millionth of a gram, which is a very, very tiny amount indeed.

The following are the United State’s RDAs (Recommended Daily Allowances) for copper at different stages of life.

Copper RDA chart

So those are the recommended minimum levels. What about maximums? Officially, the upper limit of copper for adults is 10,000 mcg per day. But it may also be the case that the official maximum levels should be lower. As many scientists are fond of saying, “More research is needed.”

Dietary Copper Sources

Copper is in a variety of foods. And the foods highest in copper are animal-derived products such as organ meats, oysters and other seafood, poultry, and red meat. Meat products are the only foods that will put you anywhere near the upper limit of 10,000 mcg per day. For example, three ounces of pan-seared beef liver has over 12,000 mcg of copper.

But you don’t have to eat animal products to meet your RDA of copper. Many plant-based foods are good sources of copper, too.

Here are some of the top plant-based sources of copper:

Dietary copper sources - copper in food infographic

Copper Deficiency

If clinical copper deficiency is present, symptoms can include anemia (not enough red blood cells and/or not enough hemoglobin in the blood), bone and connective tissue abnormalities, and neurological problems.

But since so many foods contain copper, deficiency is generally less about intake and more frequently due to intestinal problems (such as Celiac disease) or genetic conditions. Maintaining adequate copper levels in the body is mostly dependent on absorption from the intestines. As a result, copper deficiency is relatively uncommon among the general population.

Your body also has the ability to modulate its copper absorption rate based on availability. It generally increases the absorption rate if your diet contains less copper.

However, copper levels are not typically assessed in routine testing as there isn’t a reliable biomarker for copper status. Blood levels of copper and ceruloplasmin (CP) concentrations are sometimes used in people with a known deficiency (such as with Menkes disease). But factors such as infection, pregnancy, and even some cancers can affect the accuracy of these levels.

Zinc Supplementation and Copper

However, there’s a cause of copper deficiency that is in your control and has been seen more frequently since the start of the COVID-19 pandemic: zinc supplementation. Zinc was one of many dietary supplements recommended during the height of the pandemic as a means to bolster immune defense.

While zinc can help prevent and fight infections, there is the issue of too much of a good thing. Excessive zinc intake (more than 50 mg a day) has been shown to interfere with the body’s absorption of available copper. As a result, copper levels in the body can drop to dangerous levels and cause symptoms of deficiency.

High doses of vitamin C (over 1,500 mg a day) or supplemental iron may also induce copper deficiency by competing with copper for absorption in the intestine. This is one reason to be cautious about taking large amounts of supplements on an ongoing basis.

Copper Toxicity

There are also a few ways to have dangerously high levels of copper in your body. That condition is most frequently associated with Wilson disease, a rare inborn error of metabolism that starts by overloading the liver with copper, and then moves on to the brain and other tissues.

People can also get acute copper poisoning from drinking beverages stored in copper-containing containers, as well as from contaminated water supplies. The US Environmental Protection Agency has set upper limits on copper in drinking water at 1.3 milligrams per liter, while the World Health Organization is okay with the slightly more lenient 2 milligrams per liter.

Copper can enter your drinking water through corroded copper pipes, so if you live in an old house or have well water, you may want to get your water tested.

Excessive amounts of copper can cause abdominal pain, nausea, vomiting, and diarrhea in the short term. Long-term copper overexposure can cause liver damage and kidney failure.

You can also get copper poisoning by cooking food, especially acidic food like tomato sauce, in uncoated copper cookware. (Many chefs love this cookware because copper is an excellent conductor of heat.) The good news is, most copper cookware is lined with a nonreactive metal, such as nickel, tin, or stainless steel. As long as you take care of the lining by cleaning it with nonabrasive materials, and stop using it if the lining starts to crack or flake, copper cookware can be perfectly safe.

Toxicity from Copper Supplementation

Another cause of copper toxicity is taking copper-containing supplements. Some of the most commonly found multivitamins contain copper. And some even contain over double the RDA for copper. But copper supplementation is not generally recommended.

Health care professionals like Dr. Neal Barnard actually advise against the inclusion of both iron and copper in multivitamins. Too much of either can negatively impact brain health, possibly even contributing to the development of neurological disorders like Alzheimer’s and Parkinson’s. One 2022 study based on the Atherosclerosis Risk in Communities (ARIC) cohort found that “Copper intake from supplements was associated with greater 20-year decline in global cognition overall.”

However, the amount of copper in multivitamins and other supplements isn’t the only reason there’s a risk of toxicity. It’s also because the average copper intake among US adults already exceeds the recommended amounts. With so many foods providing an abundance of copper, especially animal products that are commonly consumed as part of the modern industrialized diet, there’s no need for added copper supplementation.

In fact, getting copper from animal products may be just as bad or even worse than getting it from supplements. That same 2022 study found that dietary copper, especially when consumed with saturated fat, increased the risk of incident dementia. And since plant-based foods have lower copper bioavailability and saturated fat, there’s no known neurodegenerative effects (and less risk of copper toxicity).

Copper-Rich (But Not Copper-Excessive) Plant-Based Recipes

Goldilocks would be happy with these tasty (and simple to prepare) plant-based recipes. From savory breakfast wraps to naturally sweet chocolate chip muffins, meeting your copper needs (without risking exceeding them) on a plant-based diet can be easy (and delicious)!

1. Tofu Scramble Breakfast Wrap

Tofu Scramble Breakfast Wrap is a delicious morning meal that not only satisfies your taste buds but also prioritizes your nutritional well-being. You’ll get your daily copper needs met from the tofu, spinach, and avocado in this wrap. Plus, you also get the added benefits of fiber, plant-based protein, healthy fats, and plenty of other essential nutrients. This wrap is a hearty and savory way to start your day the plant-based way!

2. Green Goodness Sandwich

Green Goodness Sandwich practically overflows with fresh, colorful, and nutrient-rich veggies. The green veggies — leafy greens, cruciferous vegetables, and avocados — are all great sources of plant-based copper. And this sandwich is also piled high with other colors (which means lots of phytochemicals!) — from red tomatoes to purple onion to orange turmeric to white seeds. This nourishing meal is bursting with so much wholesome goodness, you may want to add it to your regular recipe rotation.

3. Banana Chocolate Chip Millet Muffins

Dark chocolate and millet are the copper-rich, plant-based stars of these Banana Chocolate Chip Millet Muffins. Whether you enjoy the muffins as a wholesome breakfast or an afternoon pick-me-up, you can take pleasure in knowing that you’re getting the nutrients your body needs. Indulge in the delightful flavor and nutritional benefits of Banana Chocolate Chip Millet Muffins — because a little copper can go a long way toward a healthier you!

Getting the Right Amount of Copper is Key

Although it doesn’t get the same attention as many other nutrients, copper is essential to health and vitality. It works as an antioxidant — combatting oxidative stress throughout your body. And it has research-backed benefits for your heart, brain, bones, skin, and immune system.

But too much copper can be a problem, and this may be more of a concern for people who eat large amounts of animal products that are especially high in it, take supplements with copper, or whose drinking water is contaminated with copper from pipes. The good news is that it seems most people who eat a plant-based diet will do just fine with their copper consumption. And that should please Goldilocks very much.

The post What Are Antioxidants? And What Are the Most Antioxidant-Rich Foods? appeared first on Food Revolution Network.

]]>
In the ever-evolving landscape of health and wellness, few terms pop up as frequently as “antioxidants”. But do we truly understand the word’s significance?

In this article, we’ll embark on a journey to demystify the realm of antioxidants, delving into what they are, the types of antioxidants, and why they’re essential for our well-being.

Join us as we uncover the vibrant world of antioxidants and unveil the top foods and beverages that deliver a potent dose of these health-enhancing compounds.

Oxidation and Free Radicals

“Antioxidant” is a scientific term that literally means “substance that inhibits oxidization.” So in order to understand antioxidants, it helps to first understand oxidation and what happens during this process.

Oxidation happens naturally as your cells process the oxygen you breathe and convert it into energy. During this process, electrons pass along a series of molecules in something called cellular respiration. However, some electrons break free and become unpaired, damaging cells and DNA in their search for other electrons.

Molecules with one or more electrons are called free radicals.

Some free radicals form during natural processes like inflammation from an acute injury. But others develop in response to external factors like fried foods, alcohol, tobacco smoke, pesticides, pollutants in the air, and eating an unhealthy diet.

While free radicals aren’t inherently bad (your body uses them for certain processes, like fighting off problematic bacteria), they are highly unstable and can cause damage to your DNA, proteins, and cell membranes. The key is to have a balance — enough free radicals for their useful functions but not so many as to cause damage. When there are too many free radicals, they overwhelm the body’s natural repair processes and cause health problems.

Oxidative Stress and Antioxidants

A buildup of too many free radicals in the body is known as oxidative stress.

Oxidative stress is thought to be a leading cause of age-related and non-age-related deterioration and disease, including memory loss, the breakdown of organs, autoimmune disorders, heart disease, type 2 diabetes, cancer, and even wrinkles.

And that’s where antioxidants come into play. They are the good guys in the fight against excessive free radicals and subsequent oxidative stress. Antioxidants neutralize free radicals from oxidation by giving them the electrons they need to stabilize.

This is not just a one-and-done situation, however. Every day, your body is creating free radicals. So you need to consume antioxidants daily in order to keep your cells healthy and in balance. Without antioxidants, free radicals would build up and create significant oxidative stress, putting you at higher risk for a number of chronic diseases and other health issues. This is called oxidative debt.

What’s the Solution to Oxidative Debt?

It’s estimated that we need between 8,000 and 11,000 antioxidant units per day to avoid a deficit. But the average American doesn’t even get half the minimum recommended amount of antioxidants.

This deficiency may be part of the reason why oxidative stress-related diseases, such as heart disease, type 2 diabetes, and certain types of cancer, are so prevalent in industrialized countries.

The solution? We need to consume more antioxidants.

What Are the Different Kinds of Antioxidants?

There are thousands of substances that act as antioxidants in the body. However, not all antioxidants are interchangeable or operate exactly the same way. Some antioxidants excel at fighting certain types of reactive oxygen species (ROS), such as free radicals, while others are effective only in specific parts of your cells.

Your body naturally produces some antioxidants, but most of them have to come from your diet.

While most foods contain some antioxidants, plant foods are the primary source. On average, plant-based foods contain 64 times more antioxidants than animal-based foods.

So what are the most important antioxidants to pay attention to?

Vitamin E

While there are eight forms of fat-soluble vitamin E, α-tocopherol is the most bioactive form of this antioxidant in humans. Vitamin E supports cardiovascular health and immune function, and is good for your eyes, skin, and brain. But it’s necessary to get it from food rather than supplements to reap its benefits. Top food sources include nuts, seeds, avocado, bell peppers, and mango.

For more on vitamin E, including the best sources, see our article, here.

Vitamin C

This crucial water-soluble antioxidant has actually been shown to regenerate other antioxidants. While it’s best known for preventing scurvy and maybe the common cold, vitamin C is also necessary for collagen production and can protect your skin from the sun. Top food sources include citrus fruits, bell peppers, broccoli, papaya, and brussels sprouts.

To find out more about the benefits of vitamin C, see our article, here.

Vitamin A

Technically, vitamin A is a group of compounds known as fat-soluble retinoids, rather than a single vitamin. Together, these compounds make up vitamin A, which is an important antioxidant for eye health specifically, as well as immune support and reproductive health. There are both active forms and precursors available in food, the former mainly being in animal products while the latter are found in plants.

Plant-based vitamin A compounds are called carotenoids and include beta-carotene and lycopene, as well as lutein and zeaxanthin. While not all of these carotenoids convert to vitamin A, they are all important antioxidants for good health.

For more on vitamin A and carotenoids, see our article, here.

  • Beta-carotene — This red/orange plant pigment combines with other elements to form vitamin A in your body. Top food sources include carrots, sweet potatoes, winter squash, spinach, kale, cantaloupe, and apricots.
  • Lycopene — This fat-soluble antioxidant can mostly be found in red- and pink-hued foods. The most famous source is tomatoes, but it’s also found in watermelon, pink grapefruit, pink guava, papaya, and goji berries.
  • Lutein and Zeaxanthin — These carotenoids are vital for good vision and work together to protect your eyes from oxidative stress. Top sources of lutein and zeaxanthin are cantaloupe, corn, carrots, and red and yellow bell peppers.

Selenium

This important antioxidant is actually a mineral and originates in soil, where it’s soaked up by growing plants. Selenium is crucial for reproductive hormones as well as thyroid health. Top food sources include Brazil nuts, brown rice, mushrooms, oatmeal, and spinach.

Zinc

The mineral zinc can work as an antioxidant in the body. However, it also works synergistically with other antioxidants to increase their impact. Zinc is essential for DNA protection, wound healing, and the health and functioning of your immune system. For some people, leading sources of zinc are seafood like oysters, crab, and lobster. But good plant-based sources include nuts, seeds, whole grains, and legumes.

For more on the benefits and risks of zinc, and how much you need, see our article, here.

Polyphenols

Polyphenols are a category of pigments, of which the largest group is called flavonoids. They include subgroups like flavones (luteolin and apigenin), anthocyanidins (malvidin, pelargonidin, peonidin, and cyanidin), flavanones (hesperetin, eriodictyol, and naringenin), and isoflavones (genistein, glycitein, and daidzein). Best known for their disease-protective effects, polyphenols can be found in many different types of plant foods, including fruits, vegetables, whole grains, and legumes. Coffee, tea, and dark chocolate are also popular sources of polyphenols.

Omega-3 Fatty Acids

These polyunsaturated fatty acids come in three main forms: eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA). Some plant foods have ALA, but EPA and DHA are found mainly in fish, certain sea vegetables, and algae. The human body can convert ALA to EPA and DHA, though the efficiency of conversion varies from person to person.

Some people are efficient converters and may do just fine if they eat plenty of ALA. Others benefit from a direct form of DHA and EPA — whether from fish, fish oil, or from an algae-based supplement. Popular foods highest in ALA are flax seeds and chia seeds, with moderate amounts in hemp seeds and walnuts.

Omega-3s are beneficial for brain and heart health along with possessing anti-inflammatory and immune-supporting qualities.

For more on omega-3 fatty acids, including the best sources and how much you need, see our article, here.

Are Antioxidant Supplements Worthwhile?

Many antioxidants are available as highly concentrated supplements. So how does that compare to eating them in food directly?

In a 2004 study published in the American Journal of Clinical Nutrition, researchers put some participants on a fruit- and vegetable-heavy diet while giving others a supplement containing the same antioxidant nutrients.

The study leaders concluded that dietary intervention was better than the supplements at combating oxidative stress.

Foods contain a variety of antioxidants that work synergistically, so they tend to be more effective than supplements, which offer nutrients in isolation.

In fact, the majority of studies on antioxidant supplements have concluded that they provide few, if any, significant health benefits.

Risks of Antioxidant Supplements

While I’m not aware of any research that shows problems ensuing from overconsumption of antioxidants from food, it does seem that some antioxidants can be harmful when taken excessively in supplement form. For example:

  • Beta-carotene: A 1996 study published in The FASEB Journal found that beta-carotene supplements may actually increase lung cancer incidence in smokers. This conclusion was also confirmed again in a 2019 randomized, double-blind trial among Finnish men.
  • Vitamin E: A 2005 meta-analysis published in the journal Annals of Internal Medicine found that taking a daily dose of 200 IU of vitamin E per day did not raise the risk of death and had possible health benefits. However, the researchers found that for those taking daily doses of 400 IU or more, the risk of death was about 10% higher than among those taking placebos.
  • Selenium: High levels of selenium supplementation have been linked to type 2 diabetes, high triglycerides, prostate cancer, heart disease, and issues with immune and thyroid function.

Top Antioxidant-Rich Foods

12 High Antioxidant Foods

In a 2010 study published in Nutrition Journal, researchers measured the antioxidant concentration of more than 3,100 foods, including everything from nuts and seeds to breakfast cereals and grilled chicken.

Their conclusion? “Antioxidant-rich foods originate from the plant kingdom while meat, fish, and other foods from the animal kingdom are low in antioxidants.”

Here are 12 of the top antioxidant-rich foods and spices; and remember, it’s important to eat organic as much as possible because pesticides can also create free radicals in our bodies:

1. Clove

The study mentioned above ranks clove as one of the foods with the highest antioxidant capacities thanks to its high levels of phenolic compounds. Clove is also known for its antimicrobial and anti-inflammatory capabilities, making it an important food for immunity. While often associated with the holidays, ground clove has a sweet-meets-savory flavor and can be used in desserts, mocktails, soups, and many other flavorful dishes.

2. Pomegranate

Both pomegranate arils and juice have a high antioxidant content due to their flavonols, vitamin C, and the anthocyanins that give them their color. The compounds in pomegranates make for effective free radical scavengers and can reduce oxidative stress. Use the arils in salads and desserts, and the juice in dressings, marinades, and beverages.

For more on pomegranates and their benefits, check out our in-depth article on them.

3. Artichokes

According to the aforementioned Nutrition Journal study, artichokes are among the top antioxidant-rich veggies. But don’t just eat the hearts — the leaves contain a lot of the good stuff, including phytochemicals and flavonols! If you’ve never cooked whole artichokes, it’s easier than it appears. Find out more in our article, Artichokes: Nutrition, Benefits, & How to Cook and Eat Them.

4. Oregano

A great addition to plant-based pizza or almost any savory dish, oregano is big on taste and nutrient density. Research has found it to be a strong antioxidant due to the phenols carvacrol and thymol.

You can easily grow oregano at home in an indoor or outdoor garden, along with other antioxidant-rich herbs, such as rosemary, thyme, and sage. We use it in our Vegan Feta, and it is absolutely delicious!

For more on oregano, see our article, here.

5. Allspice

This versatile spice contains vitamin A, vitamin C, eugenol, quercetin, and tannins. Often used as a folk remedy, allspice has antioxidant properties that are protective against cardiovascular disease, digestive disorders, and obesity. It’s commonly added to sweet dishes and baked goods, or for a more robust flavor, try adding it to stews, curries, and soups. Some people even like it in lasagna sauce!

6. Cinnamon

While not quite as potent as clove, cinnamon is another fragrant spice commonly used in baked goods and other sweets that’s a powerful antioxidant. It’s also known for its specific ability to relax blood vessels, making it a valuable functional food for metabolic disorders. To reap its full benefits, use it with other nutrient-dense foods like oats or legumes.

7. Moringa

While you might expect to see other leafy greens on this list such as kale or collard greens, moringa packs an even more powerful punch. Although not as common as these other leafy greens, moringa is becoming more available either fresh or powdered. It’s a good thing, too, because it’s loaded with polyphenols, carotenoids, and vitamin C. And its capability to fight cell damage also gives it antitumor potential in fighting multiple types of cancer. Include it in smoothies and other beverages, along with soups, stews, and curries.

For more on moringa, read our in-depth article, Meet Moringa: What Is This Transformative Superfood Good For?

8. Blackberries

A 2023 study on blackberries showed they have powerful antioxidant, antimicrobial, and anti-inflammatory activity. It also found they could have applications in both the prevention and treatment of various diseases linked to oxidative stress due to their high levels of anthocyanins, as well as vitamins A and C, carotenoids, and other phytochemicals. You can use blackberries however you use other berries, such as in smoothies and smoothie bowls, salads (including fruit salads), baked goods and other desserts, and mocktails.

If you’re interested in creative ways to enjoy berries, check out our article, 5 Healthy Berry Recipes & How to Use Berries.

9. Sunflower Seeds

Of all the most eaten seeds, sunflower seeds rule them all in terms of antioxidant capacity. Sunflower seeds are high in vitamin E and also contain omega-3 fatty acids, polyphenols, and flavonoids. Although they’re plenty healthy on their own, sprouting the seeds may increase their antioxidant content. You can use sunflower seeds or sprouts in salads, granola, homemade crackers and other snack foods, and in veggie burgers.

10. Dark Chocolate

Chocolate may be responsible for up to 20% of antioxidant consumption in the US and Europe. But when it comes to chocolate, the higher the percentage of cocoa, the better. Dark chocolate has a wealth of antioxidant compounds including polyphenols, flavanols, and catechins. However, if you’re going to eat dark chocolate, you may want to find out the lead and cadmium content as heavy metals have become a concern. You can use chocolate in desserts like nice cream and baked goods, smoothies, overnight oats, or granola.

11. Walnuts

Of all the commonly eaten nuts, when it comes to antioxidants, walnuts reign supreme. In fact, walnuts are one of the plant foods consistently ranked high in terms of antioxidant capacity. They had the highest level of polyphenols out of nine different nuts in one study, and showed potential for inhibiting atherosclerosis and preventing heart disease. Walnuts go well in baked goods, granola, oatmeal; sweet or savory side dishes; and in salads, sauces, and dressings.

12. Coffee

This popular beverage turns out to have loads of antioxidants such as flavonoids and quercetin. In fact, in many different countries, including the US, coffee is the #1 source of antioxidants — by a wide margin. Some researchers even consider caffeine to be an antioxidant, of which coffee also has plenty. Drink coffee straight to get the most bang for your buck. What you put in your coffee matters, as sugar and dairy can have harmful effects on your health and can decrease the coffee’s antioxidant effects.

For more on coffee, check out our in-depth article, here.

Antioxidant Recipes

The healing benefits of antioxidants never cease to amaze us, and what’s even more amazing are all the tasty ways you can consume them daily! Antioxidants are found in both sweet and savory plant-based foods, so no matter which tastes you prefer, we’ve got something for everyone with these antioxidant-rich recipes!

1. Morning Mocha Smoothie

Morning Mocha Smoothie

Coffee and chocolate may be two of the most soul-satisfying antioxidant-rich foods on the planet. Featuring them together creates a flavor combination that is simply blissful! Because you get two superfood stars in one scrumptious smoothie, you get tremendous amounts of polyphenols (a potent type of antioxidant). With the addition of bananas, dates, walnuts (which are also rich in antioxidants), and hemp seeds, you get a nutrient-powered smoothie that will surely give you a boost of energy to start the day!

2. Grilled Romaine, Sunflower, and Pomegranate Salad

What Is Selenium and Why Is it Important for Health? https://foodrevolution.org/blog/selenium-benefits-and-foods/?utm_source=rss&utm_medium=rss&utm_campaign=selenium-benefits-and-foods Wed, 25 Oct 2023 17:00:00 +0000 https://foodrevolution.org/?p=44627 Selenium, once thought to be poisonous, is now recognized as an essential nutrient. It plays a key role in many aspects of your health, including metabolism, immunity, and protection against various diseases. But can you get too much of this nutrient? What are the best food sources of selenium, and can you get enough from a plant-based diet?

The post What Is Selenium and Why Is it Important for Health? appeared first on Food Revolution Network.

The answer to “Is it good for you” questions is often “It depends on the dose.” For example, is water good for you? Eight cups a day, yes. Your house under surging rivers of it, no. Is iron good for you? Eating about 18 milligrams a day, for many people, absolutely. Getting clocked on the head by a 9-pound skillet? Not so much.

One of the poster children for dose dependence is the mineral selenium. It’s a trace element essential for human health, and science didn’t figure that out until the 1950s. Before then, most researchers were certain that it was as toxic as arsenic and, therefore, had no place anywhere near human mouths. They weren’t entirely wrong, as too much selenium is very bad for you indeed.

Selenium gained notoriety as a toxin long before scientists realized it was essential for health. While the first reported case of what was probably selenium poisoning goes way back — all the way back to Marco Polo, who wrote about a disease he encountered in 13th-century China that rotted horses’ hooves — it wasn’t until the 1930s that selenium became notorious as a potentially toxic element.

After eating plants with high selenium content over a period of time, animals like horses and cattle developed a disease graphically named the “blind staggers,” which featured such symptoms as blindness, loss of muscle control, disorientation, and respiratory distress.

And then, in 1957, scientists discovered a health benefit to the element when selenium supplementation was shown to prevent necrosis of the liver in rats. (Our view on the use of animals in medical research is here.)

Further biochemical research found that selenium was essential for the function of an important group of antioxidant enzymes called glutathione peroxidases. That function appears to help with the prevention of several diseases, including cardiovascular disease, cancer, thyroid problems, and neurological disorders.

So in this article, we’ll look at some of selenium’s most important benefits when it comes to your health. And since it’s critical for your survival, but too much can poison you, we’ll explore exactly how much you need. We’ll also identify the best sources, and set you up for selenium success if you eat an exclusively plant-based diet.

What Is Selenium?

Selenium, or Se on the periodic table, is a mineral found in soil. It exists in two forms: organic and inorganic. Plants can uptake the inorganic variety and transform it into organic selenium, as either selenomethionine or selenocysteine, which are bound to amino acids and help build proteins in plants, animals, and people. Like vitamins and certain amino acids, selenium synthesis doesn’t happen on its own in the body. Therefore, it’s necessary to get it from diet or supplementation.

First discovered in 1817, selenium means “moon” in Greek. It got that name when its discoverer, Jons Jacob Berzelius — who had a sulfuric acid factory in early 19th-century Sweden — originally mistook it for another recently discovered element, tellurium, which means “Earth element.”

The mistaken view that selenium and tellurium were the same arose, apparently, from the fact that they both smelled strongly of horseradish when burned! When he realized his mistake, Mr. Berzelius simply named it after the nearest heavenly body to the earth, which of course is the moon.

While tellurium is relatively rare and pretty much always hazardous to human health, selenium has a number of important uses in the body and is beneficial to health in appropriate doses (which we’ll go over shortly).

Selenium Benefits and Uses

Once scientists got their heads around the idea that selenium did things other than giving livestock the blind staggers, they began finding positive effects of selenium pretty much everywhere they looked. We now know that selenium supports cardiovascular health, cancer prevention, kidney and respiratory function, inflammatory response, thyroid function, and the body’s ability to fight infection.

Is Selenium Good for the Heart?

Researchers in 2006 looked at 25 studies, dating back to 1982, that measured both incidence of coronary heart disease and levels of selenium found in participants’ blood and/or toenails. They found that a 50% increase in selenium concentration translated, on average, to a 24% decreased risk of heart disease.

Keshan’s disease, which causes enlargement of the heart and palpitations along with cardiomyopathy and heart failure, is also thought to originate from selenium-deficient soil. First reported in Keshan County, China, the disease killed thousands from the 1930s–1960s until selenium supplementation came along, leading to a reversal in the disease for many.

Selenium and Cancer

Some research suggests that supplementing with selenium can help prevent cancer, particularly for people who have low selenium levels to begin with, or who have a higher-than-average risk of developing cancer.

In one meta-analysis of randomized controlled trials, researchers found that taking selenium supplements seemed to lower the overall chance of getting cancer.

We’ve also seen that patients with some cancers, including cervical, ovarian, endometrial, breast, and thyroid cancer, show reduced selenium levels. But correlation is not causation, and it can be hard to know whether selenium deficiency causes cancer, or whether cancer causes low selenium levels. That’s why it’s significant that one study found that selenium supplementation caused regression of the CIN1 type (cervical intraepithelial neoplasia grade 1, in case you were in suspense about that) of cervical cancer.

A 2016 meta-analysis of six case-control studies also found that people with the highest intake of selenium had a significantly reduced risk of developing pancreatic cancer.

And selenium definitely shines when it comes to reducing the risk of gastric cancer (aka stomach cancer). A 2016 meta-analysis of eight studies found that people with higher levels of selenium had a lower chance of getting stomach cancer, and were also less likely to die from the disease if they did get it.

Selenium COVID Benefits

An intriguing 2023 study even looked at whether selenium levels in the blood have an impact on the development and severity of COVID-19. The researchers found that, on average, healthy people had higher selenium levels compared to those with COVID-19 symptoms. Whether COVID-19 lowers selenium stores or whether low selenium levels make it more likely to contract COVID-19 is still an open question that deserves further research.

Selenium and Asthma

Asthma is another condition where selenium appears to play a role — though here, too, we don’t yet understand which way the causal relationship goes. But, we do know that both adults and children diagnosed with asthma have lower selenium levels than those without the disease. And the less controlled the condition, the lower the levels of selenium.

Selenium and Kidney Disease

If selenium and your kidneys ever posted their relationship status on social media, it would definitely include the phrase “it’s complicated.” On the one hand, an analysis of 12 years of data for over 30,000 people showed that those who ingested more selenium had a lower risk of kidney stones compared to those who had less. This was especially true for younger people, males, and those who were overweight or obese.

On the other hand, a 2022 study suggested that higher selenium levels may impair kidney function. Using a statistical technique called Mendelian randomization (it’s also complicated, but basically it uses genes to “randomize” participants without having to actually put them into different groups with different treatments), researchers concluded that elevated levels of selenium are a causative factor for kidney function impairment.

Clearly, with selenium, not too much and not too little is the key.

Does Selenium Help with Inflammation?

Selenium also plays a role in reducing the kind of chronic inflammation that’s a root cause — or significant contributor — to many health conditions, including cardiovascular and most autoimmune diseases.

One of the most common ways researchers measure inflammation is through a biomarker called C-reactive protein, which they affectionately nickname CRP. CRP production happens in response to inflammation. So, if you can measure CRP levels, you have a proxy for the amount of inflammation in the body. A 2023 meta-analysis of 13 studies found that higher levels of selenium are associated with statistically significant (and, just as importantly, clinically meaningful) reductions in CRP levels.

Selenium and Thyroid Health

Selenium is important for the healthy functioning of your thyroid, the butterfly-shaped gland at the base of your neck that regulates metabolism, among other things. Selenium deficiency can lead to hypothyroidism (meaning the thyroid is underactive), which causes sluggishness and weight gain.

Supplementing with selenium has been shown to improve an autoimmune disease that targets the thyroid gland called thyroiditis (literally, inflammation of the thyroid). Other thyroid conditions that may benefit from selenium include Graves’ disease, Graves’ orbitopathy, Hashimoto’s thyroiditis, and cretinism.

How Much Selenium Is Necessary?

Here’s a handy-dandy chart for you to print or copy in case you’re into scrapbooking about your essential nutrients. In the case of selenium, the recommended intakes are in micrograms per day (µg/day).

Age Male (µg/day) Female (µg/day) Pregnancy (µg/day) Lactation (µg/day)
Birth to 6 months 15 15
7–12 months 20 20
1–3 years 20 20
4–8 years 30 30
9–13 years 40 40
14–18 years 55 55 60 70
19–50 years 55 55 60 70
51+ years 55 55

Selenium Content Variability

To recap: Selenium is an essential nutrient that’s found in soil. But not all soil is equally rich in it, so the selenium content of food depends on where it was grown (or, in the case of animal products, where what the animal ate was grown).

Within regions, there’s a huge variability in selenium concentrations, even from field to field. In the upper Midwest of the United States, researchers found a huge range in selenium content in various foods. How huge? Check out these examples:

Food Low (in µg/100 g) High (in µg/100 g)
Wheat flakes 11 774
Wheat 14 803
Beef 19 217

It gets worse. A 1996 study with the riveting title, “Selenium content of foods purchased in North Dakota,” reported that two brands of the exact same product, masa harina corn meal, bought at the same store, differed in their selenium content by a factor of 1,000%.

So what’s a person to do?

The most common “selenium hack” is to consume one or two Brazil nuts per day, which can deliver, on average, 96 micrograms of selenium (almost double an adult’s daily requirement). Brazil nuts are also highly variable in how much selenium they contain, with a low of 0.03 and a high of 512 micrograms per day (in other words, the nuts with the most selenium have over 17,000 times more than the ones with the least). But most of them contain a decent amount.

There is, however, a good reason to go a little easy on the Brazil nuts, which is their relatively high concentration of barium, an element that is known to be toxic when consumed in large amounts or over a long time. It’s unlikely to be a concern with a nut or two per day, but if you down a whole package of Brazil nuts, you’re liable to get a fairly massive dose of selenium, with a potentially concerning helping of barium on the side.

Also, if you take supplements, check to see if any of the formulas you’re taking contain selenium. If any of them do, that may well provide adequate selenium, in which case there is no need to eat a Brazil nut or two per day.

Foods Rich in Selenium

In general, there’s an association between the protein and selenium content of foods, with the highest-protein foods containing the most selenium. And since selenium is routinely added to animal feed to address selenium deficiency in human populations (though not in quantities that lead to the blind staggers), meat and other animal products tend to be high in the mineral.

If you don’t consume animal-derived products, the richest sources of selenium — aside from Brazil nuts (which are really in a class of their own) — are grain products such as cereal, pasta, and bread. To get the most selenium, choose whole grain products, which contain about twice as much selenium as refined ones. A single cup of cooked oatmeal contains about 40% of the recommended daily intake for an adult.

Some seeds, such as sunflower and sesame (including seed pastes like tahini), also contain a decent amount of selenium. Nuts other than Brazil nuts contain very small amounts of selenium — it’s like since they can’t compete, they’re not even trying. Legumes, including soybeans and soybean products, also deliver small amounts of selenium.

If you’re curious about the selenium status of just about every food you can think of, here’s a comprehensive database courtesy of the USDA.

Does Selenium Come with any Risks?

Obviously, you’ve got to treat any nutrient that can cause the blind staggers with a certain amount of respect. Even if you’re not a horse spending 20 hours a day munching on selenium-rich fodder you can overdose on selenium. Fortunately, there are really only two reliable ways to accomplish this dubious and dangerous achievement: through supplementation, or by eating very large amounts of Brazil nuts on a regular basis.

Some folks learned this the hard way after taking a particular liquid selenium supplement in 2008 that contained roughly 200 times the selenium content than was advertised on the label. According to the case report that was published in 2010, they developed symptoms such as fatigue, hair loss, joint pain, nail discoloration, and nausea within two weeks. The symptoms persisted for 90 days or longer.

The Food and Nutrition Board of the US National Academies of Sciences has set the Upper Tolerable Limit for selenium intake at 400 µg/day. The World Health Organization and the governmental advisory boards of Australia and New Zealand agree, while the “safe upper limit” in the UK is a slightly higher 450 µg/day. If you stay below those limits, it seems you’re highly unlikely to wind up with any toxicity issues.

Is Selenium Supplementation Helpful?

Too much selenium is not good news — but so is not enough. Fortunately, diets deficient in selenium are seldom seen in developed countries. In some places where the soil is selenium-poor and people rely on locally produced foods for the vast majority of their calories, population-wide selenium deficiencies can occur (like what was seen with Keshan’s disease in China).

In the United States and other modern societies, however, the vast majority of people get adequate amounts of selenium. However, studies from Europe do show lower serum concentrations of selenium in vegans and vegetarians, compared to omnivores. In fact, researchers found that one-third of vegetarians and 40% of vegans had selenium levels below 50 µg/L, which might be considered low.

But the bottom line on supplementation for most people is that it’s probably not necessary, as even those on the lower end are within reference ranges. Also, the population studies were conducted in Europe, and so may be less relevant to residents of North America, the vast majority of whom ingest adequate amounts of selenium.

And as with many nutrients, selenium supplementation may carry unpredictable effects. Food is not just a collection of isolated nutrients — it’s more of a symphony, with all of the components coming together to create a greater whole. And supplementing with even low levels of selenium could, at least potentially, have effects that aren’t what we might have anticipated or intended.

A 2007 study followed 1,200 people who lived in a part of the US where selenium consumption is low. Half were given 200 micrograms per day of selenium, and the other half received a placebo. Over an average of almost eight years of follow-up, the selenium group was 55% more likely to develop type 2 diabetes. And those who were found to have the highest blood plasma selenium levels were almost three times more likely to develop the disease.

And in other studies, high levels of selenium supplementation have been linked to prostate cancer, heart disease, and issues with immune and thyroid function.

If you want to be on the safe side, you can “supplement” with a single Brazil nut per day, which, on average, will give you all the selenium your body requires while staying well below the safe upper limits mentioned previously. Personally, I think Brazil nuts taste better than any vitamin I’ve ever chewed on! And I like the fact that they are, in fact, a food.

Plant-Based, Selenium-Rich Recipes

By enjoying a colorful and varied plant-based diet, it may be easier to get enough selenium per day than you realize. From our creamy Brazil nut butter to our juicy All-American plant-based burger, these recipes are a great source of nourishing minerals and are a delight to devour!

1. Brazil Cashew Nut Butter

Brazil Cashew Nut Butter

The mild, buttery flavor of Brazil nuts makes them an excellent choice for delicious nut butter. And since they’re outrageously high in selenium (more than any other nut), a little bit goes a long way in terms of meeting your selenium needs. We’ve combined them with cashews for this nut butter recipe, which adds even more creaminess and a balance of minerals such as selenium, magnesium, and zinc.

2. Walnut and Lentil Stuffed Mushrooms

Walnut and Lentil Stuffed Mushrooms

Nearly every wholesome ingredient in these scrumptious and savory Walnut and Lentil Stuffed Mushrooms contributes to your daily selenium needs. With roughly 32µg of selenium per serving, these little bite-size beauties check all the culinary boxes from nutrition to flavor and could make a great appetizer at your next plant-based gathering!

3. All American (Plant!) Burger with Dehydrated Mushroom Bacon

All American (Plant!) Burger with Dehydrated Mushroom Bacon

Sink your teeth into this juicy All-American (Plant!) Burger. This juicy burger is made with a base of hearty brown rice, savory kidney beans, and naturally sweet root vegetables (beets and carrots, to be specific). It’s also topped with smoky, umami, and crunchy Dehydrated Mushroom Bacon. The All-American burger also comes with a good concentration of selenium per serving, thanks, in part, to the mushrooms. What’s more, this is a delicious and nut-free way to boost your selenium intake.

Selenium Is Important for Health — in Moderation

Selenium is a trace element essential for human health, with roles in metabolism, nervous and immune systems, DNA synthesis, thyroid function, and reproductive wellness.

While animal foods tend to be highest in selenium, there are many plant-based sources, and most people who eat foods from a variety of soils are getting enough selenium in their diets.

Supplementation can lead to excessive selenium, so for most people, it may be safest to stick to dietary sources. A single Brazil nut per day, for example, provides more than enough selenium without spiking blood levels into dangerous territory. Plus, it’s a food.

Tell us in the comments:

In this article, you’ll discover how to easily collect food scraps in your kitchen to create compost and keep them out of the waste stream.

The post Kitchen Compost: Turning Trash into Treasure appeared first on Food Revolution Network.

]]>
One of the most powerful ways to combat global climate instability and environmental degradation is right at your fingertips: keeping food scraps out of the waste stream and instead giving them new life. Because in nature, there’s no such thing as garbage; it’s all recycling.

Think of a tree losing its leaves, which end up on the ground. Little critters (that’s a fancy scientific term, which I like to imagine translates as Tinius Buggiums in binomial nomenclature) use them to stay warm, munch them down, and then poop out rich soil. When the critters die, they get digested by other organisms, and their nutrients get absorbed into the tree roots. Or if they get eaten by birds, they get converted into bird poop, which also feeds the soil under the sycamore the bird was perching on.

When humans rake up and bag the leaves, or for that matter, mow a lawn and remove the grass clippings, they’ve broken the cycle. So to keep the trees and lawns alive, they may in turn replace the missing nutrients with synthetic fertilizer. And they need to find a place to store all the plastic bags full of yard waste.

Similarly, when we don’t return food scraps to gardens and farms, we create two problems that don’t exist in nature: where to put ever-growing heaps of trash, and how to grow food in increasingly depleted soil.

That’s where composting comes in — that is, putting the scraps in a place where nature can do its thing.

But what if you have little to no outdoor space, or live in an apartment? What can you do with your kitchen scraps then?

The good news is that there are many ways you can keep food scraps out of your waste stream even if all you have is a little space in a basement, garage, spare room, or even just on your kitchen counter.

So how can you start composting in your own kitchen? What are your options? What tools do you need? And how can you ensure you don’t end up with a kitchen that smells like the bottom of a restaurant dumpster?

Why Save Your Food Scraps?

As planet-friendly as a diet may be, if it’s generating a lot of food waste, it can still be a real burden on the planet.

When food scraps rot, they release methane, a greenhouse gas that traps 84 times more heat than carbon dioxide. Many of our landfills turn into huge steaming piles of methane-emitting organic waste, which seriously compromises any plans of reversing our ever-intensifying global climate chaos.

Some of our garbage is burned, and here, too, organic waste is a problem. When moist food scraps end up in incinerators, they require a lot of extra energy to keep the burner temperatures high enough to fully incinerate all the trash. The higher temperatures also contribute to the release of more toxins into the air. This can cause serious health problems for nearby communities (which are disproportionately low-income and communities of color).

We definitely don’t want that. So what do we do with all those food scraps? Wait for NASA to figure out how to tow them to Venus?

Here’s the thing: Kitchen scraps are actually a hugely valuable resource, one that’s mostly wasted in our broken food system. In fact, food waste wasn’t even accepted in municipal waste programs until the mid-20th century. Instead, they were often fed to backyard or farm animals, or were kept in a separate underground receptacle called a subterranean receiver.

Other creative ways to reuse food scraps and keep them out of the garbage stream include making art with them, creating skin care products, or even using them in new recipes. Depending on the scrap, you might even be able to coax it to grow into more food.

(For some more ideas, you can read our article on How to Use Food Scraps to Reduce Kitchen Waste.)

But if you aren’t ready to turn your cucumber peels into a facial mask or decorate a dress with pumpkin seeds, you may want to try composting instead. That is, letting nature take its course with your food scraps, turning rotting peels, skins, seeds, pits, and ends back into rich soil that’s ready to grow the next generation of crops.

Saving Food Scraps in the Kitchen for Compost

Food scraps are organic materials, which means they can break down and benefit the soil in the form of compost.

Some US cities are actually mandating composting, requiring that you place your food waste in a separate container from regular trash or recycling. If you live in one of those municipalities, you probably have a green bin that’s earmarked for food waste. If you’re not sure if your county or city offers municipal composting, you can check one of the maps on the environmental nonprofit GreenBlue’s website.

But even if you don’t live in a city with a composting program, there are other ways to utilize your food scraps for compost.

There are apps like ShareWaste or MakeSoil that are basically compost brokers, connecting neighbors who produce compost with neighbors who want it. It’s kind of like Tinder, but you don’t have to resort to ring lights, beauty filters, or duck face.

There are also other community composting options via local farms, community gardens, recycling centers, or private composting companies.

If you have a garden or other outdoor space, you might have room to nurture a traditional compost pile or tumbler. And if so, you might benefit from checking our guide to home composting.

And for any of these methods, you can easily collect food scraps in a small compost collection bin in the kitchen before either throwing them in a larger bin, donating them to a community program, or emptying them into an outdoor compost pile.

What Can You Compost?

While all organic materials are theoretically compostable, some will take so long to break down that for all practical purposes, they’re not appropriate for kitchen composting. Some municipal compost programs also don’t accept certain types of food scraps, such as animal products or even citrus rinds. And some accept disposable utensils and containers made of bioplastics, while others don’t. Check with your local program administrator for a full list of approved items.

For a general list of what you can compost, here’s a handy (and possibly even dandy) infographic.

Tips for Controlling Food Scrap or Compost Odors

The smellephant in the room when it comes to composting is the fact that composting is kind of an elegant name for rotting. And rotting smells. As singer-songwriter Tom Chapin puts it in his composting anthem “Good Garbage”:

“Good garbage breaks down as it goes
That’s why it smells bad to your nose
Bad garbage grows and grows and grows
Garbage is s’posed to decompose.”

So here are some suggestions for a largely odor-free compost collection experience.

Use a bin with a lid. This will not only trap odors but also help prevent pests like fruit flies. (As Groucho Marx sagely observed, “Time flies like an arrow. Fruit flies like a banana.” I had to think about that for a bit before it made sense.)

Empty your compost container regularly. This is definitely not a “set it and forget it” hobby. You’ll figure out the right schedule for you, which will depend on the amount of kitchen scraps you generate, the type of bin you use, the ambient temperature and humidity, and whether you sing to it or not (OK, I made that last one up because I wanted a longer list). Some folks empty their bins weekly; others find that daily is more appropriate.

Keep your home reasonably cool, especially in the summertime. Nothing says “strong pong” like produce rotting in a sauna-like environment.

If you can’t get rid of your scraps in a timely fashion (say, you’re going away for a few days and don’t want to return to a “Silence of the Yams” horror-scape), you can freeze them in an airtight plastic or glass container. This will halt the process of decomposition so you won’t end up with nasty aromas.

Finally, clean your container after each emptying. Check whether it’s dishwasher safe; some should be washed only by hand. Even if you’re using a compostable plastic bag, you may find that some slime has made it into the interior of your container, so a good scrubbing with a brush and soapy water can go a long way to keeping your kitchen smelling like the room in the house where food goes before it’s eaten, as opposed to after.

Compost Collection Bins

There are a range of compost bins on the market, varying in look, price, convenience, size, and capacity. You can go high-end (well, not that high-end; as of this writing, there are no Gucci or Prada composting bins) or simple, small or large, minimalist or packed with features. You can also DIY compost bins out of just about any container you have lying around.

In the end, though, their ultimate purpose is to collect and contain your food scraps so they don’t go to waste and end up in the landfill (or sit around and attract flies and perfume the air with eau de sewage).

DIY Compost Bins

Henry David Thoreau warned, “Beware of all enterprises that require new clothes.” Similarly, you don’t need to invest in a fancy compost bin to collect your food scraps. You can repurpose almost any type of container, although you’ll definitely want a lid to keep the odors in and not floating around your kitchen.

Some examples of DIY compost containers include plastic or glass storage bins, buckets, bowls, flowerpots, and empty food containers like coffee cans.

Countertop Compost Bins

If the idea of a grungy orange five-gallon bucket from Home Depot sitting between your toaster and blender doesn’t fill you with joy, you can also purchase a simple compost container made specifically for that purpose. They come in various materials, including plastic, stainless steel, bamboo, and ceramic.

Some bins can be used with compostable bags, which may make it easier to clean the inside of the container. If you’re part of a municipal composting program, check with the administrator to find out if they actually accept compostable bags, as not all do.

Some commercially available containers also come with filters made of activated charcoal or carbon to capture odors before they can escape and assault your nose (or entice it, if you happen to have the nose of a fruit fly).

Countertop Composting

Lomi

While the containers we’ve looked at so far are just receptacles for holding kitchen scraps, there are also ways to create compost right on your countertop. This type of composting is especially well suited for single people or couples without children, who generally generate less waste than larger families.

Countertop composting can also be very convenient since you don’t need to venture outside to deal with the scraps; you can gather up the peels and seeds right next to where you process the food. And it’s a great option to make a dent in food waste if you live in an apartment, don’t have outdoor space, or don’t have access to a curbside composting program.

There are three main ways to perform kitchen composting: One is powered by worms, another by fermentation, and the third by electricity.

Worm Composting

Worm composting bins take advantage of the fact that many worm varieties can eat up to half their body weight each day. And they’re diligent about rapidly converting that food into worm poop, which is a lot less gross than it sounds and is actually really nutrient-rich soil.

The fancy name for worm composting is vermicomposting (if you’re raising the worms, you’re engaged in vermiculture). It’s a pretty straightforward process: Feed worms food scraps, keep them sufficiently aerated and hydrated, maintain a liveable temperature, harvest the castings on a regular basis, and keep them contained so they don’t start casing your kitchen looking for food.

You’ll need a waterproof container with air holes (which you can either make yourself or put together from a purchased kit), moist bedding material, and worms (which you can order online, much to the delight of your mail carrier).

If seeing the worms in your kitchen makes you squeamish, it might be better to keep it out of sight under the sink or in another room, at least on those nights when you’re serving linguine or (etymology alert) vermicelli.

(If you’re a dedicated vegan, you may or may not determine that vermicomposting aligns with your ethical sensibilities. Personally, I think that building a world with less waste — and more compost! — contributes to the cause of compassion. But of course, as in all things, do what makes sense to you.)

Bokashi Composting

“Bokashi Bin Set,” by Pfctdayelise, CC BY-SA 3.0

Bokashi” means “fermented organic matter” in Japanese. And the Bokashi method of composting speeds up the process by introducing microorganisms into the mix, the same wee beasties that occur naturally in garden soil. Bokashi is usually done in a bucket with a tight-fitting lid and a spigot at the bottom (like one of those big glass beverage dispensers people use at cookouts, except instead of iced tea, you get Bokashi tea).

All you do is throw in your kitchen scraps, cover with a layer of bran inoculated with the microorganisms, and leave it alone. As the food waste pickles, it produces a dark, nutrient-rich liquid that you can access through the spigot, which, mixed with lots of water, your house plants will simply adore. Also, drawing off the liquid keeps the fermenting compost from smelling like an open sewer once you open it.

After somewhere between 10 and 21 days, you can open the bucket and behold what can charitably be called “pre-compost.” It’s not crumbly soil, but the food waste is fermented enough that it can either get mixed directly into a garden bed or finished in a compost pile or compost tumbler. Most Bokashi systems use two buckets in rotation, so you can feed scraps to one bucket while the other one is “locked” in fermentation.

You can buy Bokashi buckets and inoculated bran online or from a local garden store. YouTube searches will also show you how to make your own buckets and DIY vegan inoculated bran. Or to check out a starter kit that comes complete with bucket, spigot, and inoculant, click here.

Electric Composters

Electric composters bring the ancient art of rotting food into the modern age. They don’t just collect food scraps, but actually break them down into usable soil in a matter of hours. They do this by heating, grinding, and drying the scraps. Some include microbial pods that render the compost into garden-ready fertilizer. And they include filters, so you shouldn’t have a problem with odors.

Electric composters can come with some downsides. To accommodate their high-tech features, they’re typically bulkier than their manual cousins, and take up more counter space. They can also be expensive, both their original purchase price and their total cost of ownership, including supplies and electricity. However, some can be quite energy efficient, and the value they provide in terms of home garden fertilizer can make them more than worth the expense.

Editor’s Note: If you’re interested in a countertop electric composter, our team’s favorite is made by Lomi. They have a cute and catchy tagline: “From Trash to Treasure,” which I might have used as the title of this article if they hadn’t thought of it first.
Lomi promises an “odor-free, pest-free, mess-free” composting solution, which involves transforming food scraps into nutrient-rich plant food in just four hours. And if you purchase a machine using this link, they’ll contribute a portion of the proceeds to FRN and our mission.

Don’t Let Your Food Scraps Go to Waste

Whether you just use compost collection bins to save your food scraps for curbside pickup or try your hand at one of the countertop composting methods, kitchen composting is a great way to reduce food waste and contribute to a healthier planet.

Best of all, you don’t need a backyard or a lot of space to put your food scraps to use. From kitchen counters to basements, there are creative ways to transform your food scraps into rich, nourishing soil.

By embracing composting, you not only divert waste from landfills but also help enrich soil, foster plant growth, and mitigate the challenges of depleted farmlands. Remember, every step you take to reduce waste and to turn trash into treasure is a step towards a more healthy, ethical, and sustainable future.

Tell us in the comments:

  • What do you do with your kitchen scraps right now?

  • Do you live in a place with a municipal kitchen scrap recycling program? How easy or hard is it to participate?

  • If you don’t yet collect kitchen scraps for compost, what method described in this article seems most appealing to get started with?

Pretend you’re an entrepreneur with magical powers and a mandate to design a food crop that can save the world. You’d probably start by identifying the problems such a food would address.

The list would almost certainly include persistent droughts in many heavily populated parts of the globe, depleted soils, global hunger, nutritional deficiencies, overuse of pesticides, and climate chaos caused by the carbon footprint of burning fossil fuels.

The bad news is you probably don’t have actual magical powers that allow you to create such a food. (If you do, please apply for a job at Food Revolution Network!)

The good news is, that crop already exists. It’s called fonio (pronounced “fone-yo”), and it’s the oldest known cultivated grain in Africa.

While many Indigenous West Africans revere the grain and incorporate it not only into their diets but also into their healing and spiritual practices, its cultivation was discouraged by decades of agricultural and economic policy that sought to “modernize” the region and grow monocropped grains for food and export.

But fonio is making a comeback, growing in popularity around the world. And for good reason. It’s highly nutritious, exceptionally delicious, and environmentally resilient, making it an important crop for arid regions. Those include its home, West Africa, but also many other places around the world prone to prolonged heat and drought: southern Europe, the Middle East, North Africa, much of the US (including California, Texas, the Midwest, Sunbelt, and Southeast), Southeast Asia, and Australia, among others.

In this article, we’ll explore all things fonio. We’ll look at where and how it grows, its nutritional profile and health benefits, its environmental impacts, and why you might want to add fonio to your diet even if you don’t live in West Africa.

We’ll also cover its versatile culinary uses, and share some fonio-filled recipes.

What Is Fonio?

Richard Nyberg, USAID

Fonio, aka Digitaria exilis (Latin for “slender fingers”), has been cultivated in parts of Africa for about 7,000 years. In the Dogon language of Mali, one of the names for the plant means “seed of the universe.” In a narrative strikingly similar to the Big Bang, Dogon mythology describes the Creator bringing the universe into existence by exploding a single fonio grain.

Fonio is a member of the millet family and is related to other grains important in African agriculture, including pearl millet and sorghum. Technically, fonio is a very tiny pseudocereal, like quinoa and buckwheat — which basically means it’s a seed that’s eaten like a grain.

You may have also heard of fonio by one of its other names. These include acha, fundi, findi, iburu, Asian millet, fonio millet, pearl millet, and hungry rice. (That last name is something of a smear, implying that fonio is a lesser food that’s eaten only when there’s not enough rice.)

Fonio is native to West Africa with roughly 70% of the world’s fonio grown in Guinea. Additional production occurs in Nigeria, Mali, Senegal, and several neighboring countries.

Fonio has played a critical role in food security in these countries, especially in rural areas. For reasons that we’ll soon discover, fonio is a reliable staple crop even when other food sources are scarce.

The plant is prized for its resilience, able not just to grow, but to positively thrive in poor soil conditions. As a significant bonus, fonio is also the speed champion of grains. It’s the world’s fastest maturing cereal, going from seed to harvest in as little as 60 days. And it’s drought tolerant. In fact, the less rain the plant receives, the faster it matures.

Types of Fonio

There are two main types of fonio:

  • white fonio, called acha (the more common of the two, and quicker cooking)
  • black fonio, called iburu (less common, and higher in fiber)

Both types of fonio have a similar taste that’s been described as rich and nutty — similar to couscous (but unlike couscous, fonio is a whole grain, and it’s gluten-free!).

Fonio Nutrition

On a nutrient-by-nutrient basis, fonio appears to be one of the most nutritious of all African cereals, as well as one of the tastiest. A cup of cooked fonio (which requires a quarter cup of dry grain) provides about 170 calories, largely from carbohydrates, and a small amount of protein.

It’s also a rich source of gut-healthy fiber, providing as much as five times as much fiber as a serving of white rice. (I don’t know about you, but I sometimes opt for white rice over brown rice when I’m in a hurry since it cooks much more quickly. Well… fonio cooks even faster yet! So it is a winner by many measures of comparison.)

What about the essential amino acids that make up protein? The acha variety of fonio is particularly rich in sulfur-containing amino acids, like methionine, which is an amino acid that is typically low in legumes. However, similar to whole grains, acha is low in lysine (where legumes excel!). While we love fonio, we don’t recommend that you only eat fonio all day. Variety, including beans and other legumes, is important to ensure you’re receiving a variety of nutrients, including plenty of all the different essential amino acids.

Fonio is also a solid source of several minerals, including calcium, iron, zinc, magnesium, and copper. Since fonio is gluten-free, it can substitute for gluten-containing grains such as wheat, barley, and rye for people with Celiac disease and gluten sensitivity.

Fonio Health Benefits

Just as fonio has been systematically neglected and marginalized by industrialized agriculture, it’s also largely ignored by nutrition researchers. While its powerful nutrient profile is well-documented by modern science, the same is not true of its potential for supporting human health.

To give you a sense of the gap, when I did a search for “fonio nutrition” in the database of the US National Institutes of Health National Library of Medicine, I got 17 hits (only one of which even looked at the relationship between fonio and human health). By comparison, “corn nutrition” generated over 12,000 articles, and “sorghum nutrition” almost 1,200.

So in order to make useful statements about how fonio might help you prevent and heal from disease, we have to consider both its nutritional properties and Indigenous healing practices.

In West Africa, fonio is considered to have medicinal properties for several health conditions. In Senegal, fonio has been traditionally used to alleviate conditions such as meteorism (or bloating and abdominal distension caused by an accumulation of gas in the digestive system), constipation, and as a diuretic. Also, the Senegalese use fonio to treat blood clots, diarrhea, loss of appetite, dysentery, stomachache, chicken pox, and asthma.

In Burkina Faso, fonio is known for its slimming properties. Roasted, it’s used for wound healing. And fonio dough is given for relief of symptoms in people with type 2 diabetes.

Based on its nutritional profile and similarity to other pseudocereals, it’s probable that fonio may reduce the risk of developing both type 2 diabetes and some cancers. And with a low glycemic index (in the low 40s, to be imprecise) and favorable amounts of both resistant and nonresistant starch, fonio may help improve blood glucose management in diabetic and prediabetic patients.

Challenges Facing Fonio

“L’entraide au village: les jeunes du village se retrouvent pour la moisson du fonio d’une famille” by Toujours Passages on Flickr, CC BY 2.0.

We’ve seen that, in many respects, fonio is a near-perfect crop to address hunger on a planet that’s growing increasingly hot and dry. But now it’s time to address the one drawback to fonio: It takes a huge amount of hard human labor to produce.

Labor

In West Africa, where fonio is still a staple food for millions of people, all stages of its growth cycle are very labor-intensive.

Men harvest the grain by uprooting the plant or cutting off the grain head with a homemade knife or sickle. Threshing the grain — separating the edible from inedible parts of the plant — is just as labor-intensive. It’s done by either beating or trampling over the dry straw.

In West African countries, women perform the lion’s share of the work. Women typically do the weeding, collecting seed heads, dehusking the grain, cleaning, drying, and processing as well as selling the fonio. On average, a woman must pound fonio for an hour to dehusk just two pounds of the grain.

Although this unfairly puts a large burden on women to process the fonio and get it ready for market, from a climate perspective, the hard work does pay off. Its impact in terms of greenhouse gas emissions, as well as soil and water contamination, is minimal to nonexistent. There’s also no need for fuel to run giant harvesters and other agricultural machines, or to power running water for irrigation.

And in a region with chronically high rates of unemployment, some would argue that providing more jobs for people (as opposed to having the work done by machines produced overseas) makes good economic sense, too. Plus, there’s the fact that farmers don’t have to spend money on fertilizers or pesticides since fonio thrives in poor soil and has few natural enemies.

But in terms of growing enough fonio to feed the world, the fact that the crop hasn’t, at least so far, been able to benefit from economies of scale has been a very real stumbling block.

In the 1990s, a Senegalese mechanical engineer named Sanoussi Diakite invented a fonio husking machine that could process eleven pounds of grain in just eight minutes. However, there are very few machines in use, even today, because the $3,000 price tag renders them too expensive for the vast majority of West African farmers.

Low Demand and Rural Depopulation

Capitalizing on fonio’s status as a highly nutritious and easy-to-grow whole grain is a serious challenge facing West African farmers. In addition to the difficulties of production and postharvest processing, there are two other stumbling blocks: low market demand and rural depopulation.

Because demand from the wealthier nations is low (at least before this article was published!), farmers fear not receiving a return on their investments of money and effort. It’s more secure to grow maize, which has a predictable market, or some of the higher-margin cash crops like coffee, bananas, cashews, or cacao, which can be exported to wealthier countries.

Another obstacle is a lack of younger farmers willing to do the work of fonio farming. Many move away from rural areas to seek employment in the cities, sparking a depopulation crisis that continues to spiral as more and more people view farm life as an economic dead end.

Garnering Interest in Fonio

Some people are trying to encourage increased fonio production by creating demand for it in the US and Europe. Making fonio more fashionable, somewhat akin to what’s happened to quinoa, can mean higher profits and more stable income for farmers.

For example, Senegalese chef Pierre Thiam has been instrumental in bringing fonio to US markets. He cofounded Yolélé Foods in order to, quoting from their website, “create economic opportunity for smallholder farming communities; to support their biodiverse, regenerative, and climate-resilient farming systems.”

Yolélé Foods is also building processing facilities and collaborating with governments, intergovernmental agencies, and NGOs to train and equip smallholders for increased productivity through conservation farming.

If you’re feeling adventurous and want to try fonio for yourself, check out some of Yolélé’s fonio products online. If they’re out of stock (as seems to happen from time to time), Aduna makes an organic variety, linked here. The cost tends to be a bit higher than rice or quinoa but is lower than wild rice.

How to Cook Fonio

If you do decide to try fonio (and create more demand for it), you’re in luck. Not only is it super delicious (at least in my opinion), but it cooks super fast (just a few minutes!). This speedy quality also makes it a great option when you want to eat a whole grain but don’t have a long time to wait for one to cook fully.

One cup of fonio cooks in two cups of water and yields four cups of grain!

You can use fonio in any recipe that calls for other types of grains. Examples include grain bowls, porridge, side dishes (like couscous or pilaf), stuffed vegetable recipes, and so on.

Fonio flour has been used to make biscuits, bread, and dumplings. Some researchers have experimented with making sourdough bread using fonio. It’s also possible to make delicious cakes, cookies, and other snack foods and desserts from fonio. And you can use whole meal fonio flour to create gluten-free biscuits and other baked goods.

Fonio Recipes

This ancient West African grain deserves to be making some serious culinary waves because it offers a delightful canvas for kitchen creativity. From savory to slightly sweet, get to know this delightful ancient grain that can add wonderful texture and substantial nutritional value to your meals.

Fonio is highly versatile. There are so many ways to enjoy its taste, texture, and nutrients — and this Moroccan-inspired Fonio Pilaf will not disappoint! With savory vegetables, cooling mint, nutty pistachios, and healing spices, this is a highly nourishing all-in-one meal that is simple to prepare and a delight to enjoy as a tasty side dish or a delectable main!

The Bottom Line on Fonio

Fonio is a nutritious and versatile whole grain that has a low environmental impact. It also tastes delicious, cooks quickly, and provides many nutrients that are crucial to human health. Plus, it’s gluten-free and so is suitable for those with Celiac disease or gluten sensitivity.

Unfortunately, farmers face many challenges growing fonio because demand is unpredictable, and it’s labor-intensive to harvest and thresh. While some technology is now available to lessen that burden, until demand grows, few farmers will be able to afford to use these machines to increase production.

Increasing awareness of and demand for fonio in industrialized countries can be a win-win. Not only does the crop have the potential to improve the nutritional status of those populations, but increased demand may translate into funding to make harvesting and processing more efficient. If done in an environmentally low-impact way, this could pave the way for greater economic opportunities for farmers in West Africa.

If being a part of that solution sounds good to you, check out the recipes included above and consider making fonio a part of your life.

Have you ever had an experience where you thought you knew someone well, and then they turned around and totally surprised you? Like, the quiet guy in your yoga class turns out to be a world-famous YouTuber, or your cranky aunt used to be a trapeze artist?

Well, that’s the experience I just had researching this article about figs. I thought I knew a lot about this yummy fruit until I started digging into the topic. Spoiler alert: They’re not even fruits! And when I discovered how they get pollinated — that’s a drama worthy of a Game of Thrones episode!

But aside from their storied pollination method, figs have a lot to offer. In addition to being a delicious food, figs have also traditionally been used for healing and for some very practical purposes. For countless generations, people around the world have made poultices from fresh or dried figs, fig leaves, and fig wines. Fig stems and leaves contain latex. And, of course, fig leaves have served as, well, strategically placed garments since the Garden of Eden (at least according to some Renaissance painters).

You can also find mention of figs in both the Bible and the Quran. Biblical writers often use figs as metaphors for the physical and spiritual health of the people, with phrases like “everyone under their own vine and under their own fig tree” depicting a time of peace and prosperity. The Quran quotes the prophet Muhammad as telling his followers to eat the fig “as it cures various diseases.”

In this article, we’re going to focus on the culinary uses of figs. We’ll explore what figs are, how they taste (and how they differ from dates), the nutritional value of fresh vs dried, and their health benefits and downsides.

We’ll also look at how they get pollinated (so dramatic!), and if that process might render figs unfit for a vegan diet.

What Are Figs?

Fig trees (or Ficus carica) are native to the Mediterranean region and were one of the first plants to be cultivated.

Figs are members of the mulberry family, which, contrary to the nursery rhyme, is mostly populated by trees, not bushes to “go ‘round and ‘round.” (Other family members include the banyan, breadfruit, jackfruit, and Osage orange.)

A fig fruit (which, again, is not really a fruit) is known as a syconium. According to the Ecological Society of America, “a fig is not actually a fruit; it is an inflorescence — a cluster of many flowers and seeds contained inside a bulbous stem.” And as we’ll see, it’s that structure that makes its pollination so darn interesting.

Because the fig flower is arranged so unusually, the seeds — which are actually the ovaries of the fig — can’t be pollinated by ordinary flying insects like bees, moths, and butterflies. Instead, it requires a pollinator with the skills of a safecracker who can operate in dark, confined quarters (more on that later).

Types of Figs

There are more than 750 different varieties of fig. Some of the types you’re likely to encounter include Adriatic, Black Mission, Turkish/Brown Turkey, Calimyrna, Kadota, Celeste, and Tiger. Different types have different flavor profiles, and feature in a variety of dishes, from sweet desserts to more savory fare.

The most common dried figs in the US are Black Mission and Golden, both of which are grown in California.

Figs are light green as they grow. They may remain green or change color as they ripen, ranging from yellow to brown to dark purple, depending on the cultivar.

The Differences Between Figs and Dates

Figs and Dates

Figs and dates are two very different foods that people sometimes get confused with one another, kind of like the actors who play Harry Potter and Frodo. Here are some key differences. Frodo didn’t go to Hogwarts — oops, I mean, here are some key differences between figs and dates.

While figs originated in the Mediterranean region, dates are native to several geographical locations, including North America. Figs grow on trees, while dates are the fruits of palm trees, which are technically grasses and not trees (this is such a genus-bending article!).

Furthermore, figs grow on fig tree branches, while dates grow in clusters on offshoots from the main trunk of the palm tree. Dates contain a single pit, while figs have many small edible seeds.

When it comes to eating the fruits, they’re also quite different. Figs have three times the amount of water as dates, which also makes them much lower in calories (about four times lower, if you’re counting). So dates are a much more concentrated source of carbohydrates, mostly in the form of simple sugars. Dates are also richer sources of some minerals, such as calcium and potassium.

Nutrients in Figs

The good news is figs deliver a lot of essential nutrients. The predominant macronutrient (the one that provides calories) is carbohydrates, but they’re also rich in some vitamins and organic acids. As whole plant foods, they also provide important dietary fiber.

According to the US National Nutrient Database, two medium raw figs contain roughly 3 grams of fiber. Doing the math, this means that if you ate just 8 figs a day and nothing else, you’d still get about half as much fiber as the average US resident consumes in a day. (To be clear, I am NOT recommending the “8 Fig a Day Diet,” although someone could probably write a best-selling diet book with that title.)

However, some researchers have measured much greater amounts of fiber in different fig cultivars. According to the American Botanical Council, two fresh or 4–5 dried figs provide a whopping 12 grams of fiber.

So we have credible authorities telling us that two figs provide 3 grams of fiber, while others say the correct figure is 12 grams of fiber. It reminds me of the old saying, “A person with one watch knows what time it is. A person with two watches… is never quite sure.” So for now, let’s just say that figs are high (potentially very high!) in fiber, and leave it to the good folks at the US National Nutrient Database and the American Botanical Council to duke it out on the details.

Figs are a good source of many bioactive phytonutrients, too, including flavonoids, phenolic acids, carotenoids, and tocopherols.

(Here’s a fun article all about flavonoids, which starts with a weird story about a bunch of soldiers trying to cross a bridge.)

They’re also solid sources of potassium, calcium, sodium, magnesium, and phosphorus. What’s more, figs provide essential trace elements, including iron, manganese, zinc, and copper.

You’ll get the most nutrients if you don’t peel your figs; the highest concentrations of phytonutrients are in their skin. And darker fig varieties contain more polyphenols and antioxidant power than lighter ones.

Figs also lose some phytonutrients when dried. Studies show a loss of 29% to as much as 86% of the polyphenol content when figs are dried.

Health Benefits of Figs

In the Middle East and Mediterranean regions, figs have long been revered for their contributions to human health and longevity. The fruit, leaves, latex, bark, and roots of fig trees have been used to treat gastrointestinal, respiratory, inflammatory, and cardiovascular disorders, as well as ulcerative diseases and cancers. The various parts of the fig tree possess a wide variety of properties; they can help you poop, relax muscle spasms, fight viruses and bacteria, bring down high blood sugar, and even help your body expel parasites.

And modern scientific research has only added to our understanding of the power of figs to promote health.

Figs and Gut Health

When patients with irritable bowel syndrome add figs to their diet, they often experience decreased symptom occurrence and severity. A 2019 study gave IBS patients 90 grams of dried figs per day for four months. Compared to controls who didn’t get anything, the fig-enhanced group had reduced frequency of pain, less intestinal distention, more frequent pooping, and softer stools. Unsurprisingly, they also reported “a significant increase in quality of life.”

In a 2018 animal study, rats with induced ulcerative colitis were fed a liquid extract containing figs. The treatment had a natural laxative effect but did not lead to diarrhea, and it improved their gastrointestinal functioning. (Our view on the use of animals in medical research is here.)

Figs and Diabetes

Figs (and fig leaves) can also be deployed to treat diabetes. A 1998 study found that people with type 1 diabetes who drank tea made from fig leaves were able to lower their blood sugar immediately following meals. And a 2019 study showed that a fig leaf decoction was able to lower blood sugar in people with type 2 diabetes by about half as much as the drug metformin (after two months of treatment).

It’s not just the leaves, though — fig fruits contain a compound called abscisic acid (which should definitely be included in spelling bees) that has been shown to reduce blood sugar levels after meals.

Figs and Cognitive Decline

Studies with experimental animals have shown that figs may help us stay sharp and avoid or delay cognitive decline. One animal study compared the effects of a diet that included figs to a fig-free diet in mice that were genetically engineered to develop Alzheimer’s disease. The mice who ate figs did better on memory tests, displayed fewer anxiety behaviors, learned new things more quickly and fully, and had better motor coordination. Furthermore, the fig-eating mice had lower levels of the toxic amyloid beta proteins that are associated with the development of Alzheimer’s disease.

Are Figs Vegan?

This may seem like an odd question, but remember that Game of Thrones reference from earlier? It turns out, fig tree pollination is a bit controversial.

You see, there are two types of fig trees: wild and cultivated. And wild-growing fig trees require pollination to bear fruit. The critters that have volunteered for the job are fig wasps, a term that describes any of several hundred different, mosquito-like tiny creatures from the Agaonidae family. Each species of fig wasp pollinates only one variety of fig.

Basically, here’s how it works.

A female wasp, loaded with pollen, flies to an unripe fig and burrows into its center to deposit her eggs. While she’s doing this, two things happen. One, she spreads her pollen onto the female flowers. And two, the effort of fighting her way through the flower strips her of her wings.

Now the fig goes to work, building structures called galls over the wasp eggs and producing seeds in the flowers that don’t contain the eggs. Meanwhile, the mama wasp dies, whereupon her exoskeleton is dissolved by figgy enzymes. (Cue the emotional orchestral music.)

The heroic male wasps hatch first, and travel around the syconium fertilizing their sisters who are still pupating in their galls. (This is definitely HBO-worthy stuff!) Then they dig holes through which the fertilized females can escape with their wings intact. Once the females hatch, they fly off to repeat the process, leaving the males to die in the maturing fig.

Pretty intense family drama, huh?

As a result, some vegans do not eat figs because they don’t want to consume dead wasps, and also because animals died as part of the process that produced them. However, there’s good news if you want to adhere to a vegan diet and still enjoy delicious figginess.

First, the wasps are completely dissolved by the plant enzymes, so you are not likely to encounter a dead insect in your fig. And second, almost all figs produced and sold in the US are of the cultivated variety and are self-pollinating. This means they don’t need the sacrificial services of the fig wasps, and are considered vegan-friendly.

Fig Downsides

Aside from the fig wasp controversy, there are some other things about figs to consider. For one, some people may have to avoid them because of allergic reactions, including oral allergy syndrome. The latex in the plant may also be a source of irritation and allergy, especially if you’re harvesting figs.

Also dried (but not fresh) figs are high in compounds called salicylates, which may cause swelling, itching, hives, worsened asthma, and food intolerance symptoms in people who are sensitive to them.

The other thing about figs is that it takes a lot of water to grow them. Although they’re not as needy as some other crops like citrus, almonds, alfalfa, and pasture grasses, in places straining under multiyear droughts, such as California and Spain, this can be a problem.

On the other hand, fig trees, like almond trees, are drought tolerant, so they can be a good solution in some cases. While they may not bear fruit during times of drought, they can survive until the rains return. There are several strategies growers can implement, including mulching, thinning fruit to help the remaining fruit develop fully, and protecting trees with shade cloth during the hottest parts of the day.

One other challenge with growing figs, and I say this from personal experience, is that for some reason gophers love their roots. So if you aim to grow a fig tree, it may be wise to place a wire gopher barrier in the planting hole to protect the root ball from those sharp little teeth.

Overall, growing figs appear to be a net positive for the environment. Offsetting their water needs and their moderate carbon footprint, they don’t require heavy use of pesticides. Plus, fig trees sequester carbon in their biomass, keeping it out of the air and not contributing to the climate crisis.

“Teamwork makes the dream work.” The phrase that birthed a thousand motivational posters seems to have originated in “Let’s Go,” the theme song of the 1986 New York Mets championship baseball team.

But that doesn’t mean the concept is new, nor does it apply solely to humans. People around the world have also known that some plants, when grown together, perform better than when on their own. They can grow faster and bigger, taste better, and require less care and fewer external inputs.

That’s not how the vast majority of crops are grown these days. Large-scale commercial agriculture relies on a method called monocropping, in which huge fields contain a single species year after year.

It makes sense from an industrial perspective. By having only one crop, everything can be standardized, from sowing to watering to weeding to applying biocides to harvesting. Theoretically, monocropping provides bigger yields with fewer costs.

In practice, it turns out that monocropping is something of an environmental disaster. Its downsides include increased global food insecurity, more reliance on potentially carcinogenic biocides, and harmful climate impacts.

While replacing monocropping as an agricultural system will take time and require large-scale changes in attitudes and knowledge, you can contribute to a more earth-friendly and effective form of growing crops if you have access to a garden of just about any size.

And like the ’86 Mets, your garden crops can exceed expectations and come out of the ground as champions if you allow them to support each other. A simple way to begin is known as companion planting.

In this article, we’ll explore which plants grow well together, and why. You’ll see how plants with very different qualities and requirements can do some of the work usually performed by the gardener — including weeding and chasing away predators. And you’ll discover some natural ways to deter pests without depending on toxic pesticides.

So let’s find out how companion planting works, what the benefits are, and which edible plants work well together for a flourishing and nourishing harvest. Whether you’re a novice gardener with a few potted plants or someone looking to create a vibrant backyard vegetable garden, companion planting has something to offer.

A Brief History of Companion Planting

Growing crops together for their — and our — mutual benefit is not a new idea. Although many gardeners and small-scale farmers are just now discovering the benefits, for thousands of years, companion planting has been integral to the well-being of many Indigenous peoples.

The benefits have been material, in terms of more abundant and nutritious harvests, and spiritual, in terms of a philosophy of life that nurtures community. In one of the best-known examples of companion planting, many Indigenous groups in North and Central America sow corn, beans, and squash together.

The Haudenosaunee Confederation (you might know them as the Iroquois) of upstate New York and the Cherokee of the Southeastern US call them the three sisters, noting that like family members, the three crops share their unique gifts in ways that support each other.

While modern life often emphasizes individualism, Indigenous wisdom shows us that planting a diversity of crops together ensures a diversity of life — and nutrients. Diversity really is one of the cornerstones of healthy life. Having a variety of crops growing in a single bed or field acts as a safety net against diseases or pests that could decimate any single crop.

What Is Companion Planting?

Now that we’ve explored the philosophy of companion planting, it’s time to get practical.

Companion planting is the practice of growing two (or more) crops/plants near each other so that one or both benefit from a synergy. These can include fruits, vegetables, herbs, and even flowers. Some companion planting occurs simultaneously, such as the three sisters. Sometimes one crop is sown near the end of another crop’s growing season (a more advanced form of companion planting known as intercropping).

An example of intercropping is when peas are sown into existing spinach beds in the very early spring. The peas get a head start without ripping out the spinach, and as legumes, they add nitrogen to the soil. By midsummer, the bolted spinach stems support the growing pea vines. These types of efficiencies are frequently used in organic farming methods as they improve pest resistance and increase yield.

Companion planting isn’t just a Native American innovation; examples can be found all around the globe. Traditional European cultures also developed modes of companion planting whose use goes back to medieval times, if not earlier.

For example, French and English farmers still grow “potager” gardens consisting of fruits and vegetables sown in an ornamental layout and protected by surrounding rows of herbs and flowers. These potager beds were so named because they contained everything needed for “potage,” a healthy soup eaten at the start of the daily meal.

Benefits of Companion Planting

So what exactly are the benefits of companion planting? Why might you want different crops to share space in your garden? Here are a few of the biggest ones.

Pest Control

Since synthetic pesticides are such an integral part of modern agriculture, it’s easy to forget that they’ve only been in widespread use since the end of World War II. Before that, farmers had to rely on companion planting, among other natural methods, to control pests.

Plants use a variety of strategies to protect themselves from predators. One is to produce compounds that the critters who might munch on them find yucky tasting or toxic. And different plants produce scents and tastes to deter specific pests. So combining multiple crops in a small area can create “broad-spectrum” deterrence that benefits all of them.

You can “hide” certain crops next to other ones that have powerful scents. Herbs like rosemary and flowers such as marigold can perfume the air and camouflage crops such as white cabbage that might otherwise end up as a tasty treat for some very hungry caterpillars.

You can also engineer the process in reverse, planting crops that attract beneficial insects that eat the bugs that would otherwise love to eat your crops. Some of these good predators pull double duty as plant pollinators, which can increase the yields of some fruits and vegetables.

It’s not just teeny critters that can be deterred by companion plants. If you’ve ever grown corn in an area that’s home to raccoons and you don’t have military-grade fencing, you’ve probably experienced some vandalism. (Maybe you’ve even woken up to entire beds of stalks lying broken on the ground, the almost-ripe ears nibbled and left to rot — a situation that can try the compassion of the most committed vegan!) In a three sisters’ bed, the prickly squash leaves deter the raccoons from climbing and destroying the corn stalks.

Essentially, more plant diversity in an area equals less pest damage.

Mutual Support

Companion plants can offer structural support to each other. Taller plants serve as living trellises, offering support for climbing plants that need something to climb. In the three sisters, corn serves as a trellis for the beans. But also, beans can provide stability for the corn, which has very shallow roots. (It reminds me of a Mitch Hedberg standup routine: “My belt holds my pants up, but the belt loops hold my belt up. I don’t really know what’s happening down there. Who is the real hero?”)

There are many other structural pairings that can work. Okra can hold up cucumbers and cherry tomato bushes, and sunflowers can provide scaffolding for baby pumpkins and small summer squashes.

Planting taller and shorter crops together can extend the growing season of the smaller plants by giving them some shade and relief from the heat of late summer. This can keep them from bolting or wilting.

Soil Health and Nutrition

All living things require nutrients, which get cycled from soil to plants to animals and back to soil in a continuous loop. When you grow different plants near each other, you can accelerate and expand that nutrient cycling.

For example, some deep-rooted plants like comfrey and dandelion pull nutrients from lower layers of soil — nutrients that are out of reach of short-rooted crops like lettuce. Other nutrient accumulators include chives, parsley, and daikon radish.

Comfrey is especially useful as a “mulch crop,” meaning you can just cut off its thick green leaves and lay them down over the soil, where they not only discourage weeds and maintain soil moisture but deliver their nutrients to the topsoil as they decompose.

Another classic companion planting benefit involves nitrogen. This element is a bit of a paradox when it comes to gardening: Even though the air is about 80% nitrogen, it can be in short supply in the soil. And nitrogen is not a gardening negotiable; plants require it in order to photosynthesize and grow.

Fortunately for the plants (and for all life on earth that depends on them — no nitrogen, no protein), some species of plants have developed the ability to convert atmospheric nitrogen into a form that plants can use, a trick known as nitrogen fixation.

The vast majority of nitrogen-fixers are legumes, which include peas and beans, greens like alfalfa and clover, and peanuts. And technically, to give credit where credit is due, the legumes themselves don’t turn the nitrogen you breathe into the nitrogen plants use to grow; they partner with certain types of bacteria that grow on their root nodules who have the knack.

Including nitrogen fixers in your garden can benefit neighboring crops that require high nitrogen levels. This can reduce or even eliminate the need for chemical fertilizers that can damage the environment and make your soil less fertile and more dependent on chemicals over time.

Another way companion planting can improve soil health is by combining deep-rooted and shallow-rooted plants in the same bed, a strategy that can enhance soil structure. If your soil is compacted or has lumps of clay, for example, plant roots can muscle through and aerate the soil. And when those plants die, their roots decompose and add nourishing organic matter to improve soil tilth and fertility.

Also, having a diversity of plants in a single bed fosters a highly diverse soil microbiome. Each plant attracts its own unique microbes. And those microbes promote nutrient cycling, breaking down organic matter into nutrients the plants can absorb and use. Mycorrhizal fungi form symbiotic relationships with plant roots, helping the plants gather nutrients from a greater surface area and convert those nutrients into a usable form in exchange for carbohydrates.

And planting crops close together can protect the surface of the soil from erosion caused by wind and water.

Flavor Enhancement

If you’ve ever hung around someone who talked in a very distinctive way or had a catchphrase they repeated a lot, you may have found yourself mimicking them without meaning to. Plants are the same way — their flavors can affect each other.

Scientists have recently discovered that plants talk to each other, sharing intel on resources and potential threats so that they can make informed decisions on where to put their energy. One of the main channels of such communications is the exudates (compounds secreted by the roots) that can impact the growth and flavor of neighboring plants.

For example, when aromatic herbs are planted near certain vegetables, they can infuse their neighbors with a hint of their distinctive flavors. Basil improves the taste of tomatoes. Dill goes with potatoes not just in salad, but in the garden as well. And marjoram is a good friend to eggplant.

Sometimes the influence is one-way, but some plant combinations have a synergistic effect on each other’s biochemical processes, leading to enhanced flavor profiles all around.

Weed Control

I remember when I realized for the first time that nobody weeds the forest, and yet it’s not covered with weeds. That’s because every inch (or centimeter, in my country of birth, Canada) of ground is already covered with something.

The reason the beds of annual gardens are such weed magnets is that they’re very unnatural. The act of tilling renders the soil unprotected from the many seeds that can blow in on the wind, drop out of the backsides of birds, or lay dormant in the ground until that gap opens up and oxygen floods in.

When companion planting involves cover crops or green mulch, it can prevent those seeds from taking root or from receiving enough sunlight to start growing. Cover crops can compete directly with weeds, both while they’re growing and after they’ve finished producing.

And when companion plants allow for denser planting, there are fewer nutrients and less sunlight available for the unwanted plants we call weeds. And some companion plants secrete chemicals that inhibit the germination of weed seeds, but not the seeds of the companion.

Common Fruits and Vegetables and the Companion Plants That Benefit Them

7 Most Common Companion Plant Pairings

Things to Keep in Mind Before Trying Companion Planting

Start with flowers as companions. Growing flowers near your crops can help attract the insects that will pollinate fruit and veggie plants. They can also repel bugs and other critters that would love nothing more than the opportunity to eat your harvest before you do.

Marigolds, nasturtiums, and sunflowers are common flowers included in vegetable gardens because they work well with a variety of plants. And nasturtium leaves and flowers are edible (sweet and redolent of black pepper, if you ask me), as are sunflower seeds.

In terms of spacing, plant the companions as close together as possible without interfering with the growth of either plant. Think about how much root space they require, and whether they’ll start competing for sunlight. With some combos, you may need to split the difference between their spacings in order to optimize the benefit to both plants.

Always go for variety. A diversity of plant species will attract pollinators and beneficial insects as well as prevent disease and fungus from wiping out crops of the same family. A 2018 study of urban rice fields in Shanghai found that adding border plantings and companions to the rice reduced the need for pesticides while increasing both yields and profits.

Finally, think like a matchmaker and look for signs of compatibility when assigning plants to beds. Choose companion plants that are compatible in terms of growth habits, water and sunlight requirements, and overall nutrient and soil needs.

It’s not always a jungle out there, but while some plants thrive together, others will compete for resources.

And for extra credit, plan your garden layout to include plants with staggered planting and harvesting times. This ensures a continuous supply of fresh produce throughout the growing season, as well as minimizing empty spaces that pests or weeds might exploit, or that might be prone to soil erosion.

Recipes Using Companion Plants

While AGEs are in almost all foods, some have much higher concentrations than others. And some foods and beverages can actually counteract the damage that AGEs can do to your tissues. So what are the most effective dietary strategies to slow down the aging health problems caused by AGEs?

The first recorded mention of a “fountain of youth” comes from the Greek historian Herodotus. Writing about 2,500 years ago, he reported that members of an Ethiopian tribe, the Macrobians, routinely lived to 120 and beyond thanks to the water of a certain spring. He told us that the water was unusual in many ways: It smelled of violets; it was so light that nothing, not even wood, floated in it; and drinking it reversed aging and extended life.

Since then, the search for a fountain of youth has been a recurring obsession of kings and explorers, pilgrims and pirates. As far as I know, none of them ever found it (or if they did, they aren’t sharing any details). No spring, river, pond, lake, or sea has magically rejuvenated the bathers who submerged themselves in its water to the point where creaky elders limp in and dewy-eyed adolescents leap out.

If you’re searching for clues to living a long and healthy life, you probably need to look elsewhere. And a huge factor in the rate of aging turns out to be a class of compounds found in many of our most common (and sadly, most beloved) foods. If you want to slow down your biological clock, limiting your consumption of these foods appears to be a much more reliable and effective strategy than dunking yourself in a mangrove swamp in Bimini or a waterfall pool at the foot of a South Indian mountain.

The compounds are known to biochemists as advanced glycation end-products, which might be hard to remember except for their most excellent acronym: AGEs. As in, AGEs that accumulate in your tissues — make you age faster.

Aging isn’t just a vanity issue that sells stock image licenses to fashion magazines and anti-wrinkle creams to their readers. It’s a big deal for your overall health because, statistically speaking, the single biggest risk factor for disease and death isn’t your genes, or your diet, or how much you exercise, or whether you live downwind of a Superfund site, or whether you drink enough water or put on sunscreen, or any lifestyle or environmental factor; it’s your age.

Which means that because AGEs can contribute to the development of various age-related diseases and conditions, they can shorten your lifespan.

The good news is, you have a lot of control over the amount of AGEs you consume, which in turn largely determines the concentrations of these compounds that accumulate in your body and how much harm they get to perpetrate.

In this article, we’ll dive into the world of AGEs and their impact on your health. We’ll see how your food choices — as well as various cooking methods — can affect the formation of AGEs. And we’ll discover some simple and delicious ways to minimize AGEs in your diet — so you can increase your odds of a longer, healthier, and happier future.

What Are AGEs?

Advanced glycation end-products are harmful compounds that form through a natural process called glycation. It takes place inside your body when the sugars in your bloodstream react with proteins, lipids (fats), and nucleic acids from the food that you eat.

You can also introduce AGEs into your body fully formed, as it were. They form exogenously (that is, outside the body) when foods are browned and their outer layer becomes crispy and crunchy. This chemical reaction is known as the Maillard reaction, or nonenzymatic browning. The Maillard reaction gives foods a texture, taste, color, and aroma that most people find very pleasing.

You can also introduce AGEs into your body through drinking alcohol and smoking.

As you age, AGEs can start to accumulate in your tissues and organs. The more your blood sugar levels fluctuate, the more AGEs form, and the more the effects of glycation intensify and accelerate the aging process.

AGEs can also cross-link with various proteins in your body, leading to the formation of abnormal structures and interfering with the functioning of important molecules. This further contributes to the aging process.

Why Are AGEs Bad for You?

Advanced glycation end-products have been shown to be toxic, immunogenic (triggering an immune response, typically unwanted and over-the-top), and capable of triggering cellular injury. Another remarkably on-point acronym, RAGE, stands for Receptor for Advanced Glycation End-products. It is a receptor protein for AGEs that plays a role in the inflammatory response and has been implicated in various age-related diseases and conditions, including skin damage, respiratory disorders, neurodegenerative diseases like Parkinson’s and Alzheimer’s, cancer, type 2 diabetes, and cardiovascular disease.

Skin Health

AGEs contribute to skin aging, including the formation of wrinkles and brown spots. They affect how proteins work in the dermis (the middle layer of your skin), leading to lots of problems: decreased elasticity, delayed recovery from wounds, accelerated skin aging, and inflammation that can contribute to skin conditions like dermatitis and psoriasis.

Collagen (a type of protein found in our connective tissue, cartilage, bone, and tendons) is one of the structures most easily attacked by AGEs. Over time, AGEs can accumulate on collagen, causing the skin to turn yellow.

Neurodegenerative Diseases

Autopsies of people who died from or with Alzheimer’s disease have shown accumulations of AGEs have been found in their brain plaques, as well as in their blood serum and cerebrospinal fluid. AGEs can also hasten the ravages of Parkinson’s disease by contributing to neuronal cells’ self-destruction as well as the formation of Lewy bodies (structures associated with abnormal deposits of a particular protein in the brain).

Respiratory Disorders

The more AGEs a person consumes, and the more frequently they eat meat, the more likely they are to experience breathing problems. This includes symptoms of asthma in children, such as wheezing. Kids who consume the most AGEs typically need more asthma meds, have their sleep interrupted by wheezing episodes, and are most limited in their ability to exercise without shortness of breath.

When COVID-19 hit, many of the initial deaths were linked to an immune system overreaction known as a cytokine storm. AGE consumption appears to be linked to worsening outcomes in COVID patients due to more extensive lung damage. AGEs also can lead to severe pneumonitis (inflammation of the lung tissue) by impairing the immune response, triggering inflammation, changing the structure of lung tissue in a way that decreases lung function, and enabling bacteria to adhere more easily to the lungs.

Type 2 Diabetes

The AGEs that are created by cooking certain foods in certain ways (known as exogenous AGEs, to differentiate them from the endogenous AGEs that are synthesized inside our bodies) can be extremely harmful to people with type 2 diabetes. In addition to adding to the inflammation that can trigger the development of the disease, AGEs also contribute to diabetic retinopathy and other related issues that can damage eyesight.

Some of the vascular dysfunction associated with diabetes can be prevented by blocking the RAGE receptors. And proactively consuming a diet low in AGEs can increase insulin sensitivity, which can reduce the risk of developing type 2 diabetes in the first place.

Cancer

With cancer, AGEs can act like gasoline thrown on a fire, increasing carcinogenic processes in a wide range of cancers and promoting their malignant behaviors. A 2015 study of male members of the US-based AARP found that the more AGEs they consumed, the greater their risk of developing pancreatic cancer. And a 2022 study of over 14,000 Japanese men found that high AGE intake was significantly associated with an increased risk of liver cancer.

AGE-Forming Foods

I hope by now you’re motivated to find out where these AGEs are hiding, so you can consume as little of them as possible. So here are the five main categories of AGE-forming foods.

Meat

In the standard industrialized diet, meat is typically the largest contributor to AGE formation. They’re created when the proteins in meat get a little too friendly with sugars, particularly glucose and fructose, that can be added during processing (some examples are many forms of bacon, hot dogs, and corned beef) or via marinades.

When meat is cooked at high temperatures, especially over an open flame or on a grill, it can produce harmful compounds that contribute to AGE formation. Some of the worst offenders are heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs), which are classified as potential and known carcinogens, respectively.

Regardless of the cooking method, any blackened or charred meat will contain these compounds. The levels depend on the type of meat (beef is worst), cooking conditions, and final internal temperature.

If you’re wondering why humans tend to love the color, smell, texture, and taste of something that’s so bad for us, it’s probably because the Maillard reaction is a good indicator that the meat has been cooked enough to kill the pathogens that could kill you. From an evolutionary perspective, the AGEs that keep us from reaching old age are far preferable to the germs that could end your life in the next few hours or days.

Fried Foods

Frying and other high-heat cooking methods also increase the AGEs in foods. A big culprit here is the repeated heating and use of cooking oil in commercial settings. That oil accumulates large amounts of AGEs, which get transferred to those fries or mozzarella sticks when they’re submerged in their fryer basket.

The longer the food is exposed to high-temperature frying, the more opportunity there is for the Maillard reaction and AGE formation to occur. Even changing the cooking oil daily leaves room for lots of AGEs. Swapping out large containers of hot oil is a dangerous and not very fun job, so some restaurants or commercial kitchens schedule the task only every few days. (I asked a friend’s son who once worked in a local restaurant how often they changed their cooking oil, and he responded, puzzled, “I have no idea if they ever do.” Sometimes I’d rather not know certain things.)

Cheese

The highest concentrations of AGEs are found in aged and hard cheeses in particular, probably because they’re pasteurized and/or they spend a lot of time aging or curing at room temperature — conditions that make up a veritable AGE factory. But all dairy cheeses are potential sources of AGEs, perhaps because dairy contains large amounts of fat along with natural lactose sugar.

Processed and Packaged Foods

Processed and packaged foods are often high in AGEs. Many of them contain added sugars, and undergo high-temperature processing as they’re baked or fried. They’re high in AGEs via that good old Maillard reaction, which is responsible for the browning and flavor development in cooked foods, and which can also extend shelf life.

Sugary Foods

Since AGEs form via glycation (essentially, sugarcoating proteins and fats), foods high in added sugars, such as candies, pastries, and sugary beverages, can provide fodder for the glycation process and contribute to the formation of AGEs.

There’s data that suggests that the glycation process following high sugar intake may be a key player in the development of metabolic disturbances.

Foods and beverages with a high fructose-to-glucose ratio may promote AGE formation. These can include anything with high-fructose corn syrup, agave nectar, honey, and filtered fruit juices. A glaring exception to this rule is fruit, which is actually protective against AGE-related disease thanks to its high fiber content.

Especially worrisome are commercial soft drinks sweetened with high-fructose corn syrup, which are often high in an intermediate product of the Maillard reaction called methylglyoxal.

Why Eating a Whole Food Plant-Based Diet Is the Best Way to Avoid AGEs

You can’t avoid AGEs entirely — pretty much every food contains some. But whole plant-based foods, including fruits, vegetables, whole grains, legumes, nuts, seeds, and herbs and spices, naturally have lower levels of AGEs than animal-derived foods. And some cooking methods commonly used on plant foods — steaming, boiling, and baking — produce fewer AGEs than the higher-temperature methods like frying, grilling, and broiling that are commonly used for foods of animal origin.

It’s definitely possible to get exposed to significant quantities of AGEs on a plant-based diet if you routinely fry starchy foods like potatoes (I’m looking at you, potato chips and french fries!). These foods also produce acrylamide, another compound that may be problematic for some people when consumed in large quantities.

But even when fried or broiled until brown and crispy, most whole plant-based foods offer compounds that can mitigate the damage caused by AGEs. Many are rich in antioxidants, such as vitamins C and E, the provitamin beta-carotene that your body converts to vitamin A as needed, and various phytochemicals that help neutralize the free radicals that can contribute to AGE formation and oxidative stress in the body.

Also, the soluble fiber available from plants helps regulate blood sugar levels and can reduce the glycation process by slowing down the absorption of sugars in the bloodstream.

5 Foods (and 1 Beverage) That Prevent Glycation

You can go a long way toward reducing AGEs and RAGE in your body by avoiding or limiting highly processed foods and those of animal origin, and by using lower-temperature cooking methods that don’t produce crispy, crusty browning on the outside.

In addition to those strategies, you can also consume some specific foods that contain compounds that inhibit the glycation process, so that the AGEs you do inevitably consume have less risk of causing aging and accompanying health problems.

Berries

The antioxidants in berries help reduce the conditions that lead to glycation by scavenging and neutralizing free radicals. Polyphenols found in berries, especially anthocyanins and quercetin, may directly inhibit the formation of AGEs. And extracts made from the skins of red grapes (which are, botanically speaking, berries) were able to inhibit the creation of AGEs in a test tube containing fructose-glycated proteins.

Berries also deliver anti-inflammatory and blood sugar-balancing effects.

Spices

Many spices, some commonly used in modern kitchens and some still awaiting their turn as superfood du jour, have been shown to prevent AGE formation through their powerful antioxidant activity. Examples include star anise, cinnamon, allspice, and cloves, which are staples in many traditional cuisines around the world. And good old black pepper also performed well at this task.

Other powerful anti-AGE spices include garlic and turmeric which contains the powerful antioxidant curcumin.

Nuts

Nuts, led by walnuts and pistachios, are great at inhibiting the glycation process in early and intermediate stages, before they even have a chance to reach the end stage indicated by “AGEs.” They are also powerful anti-inflammatories, helping to prevent damage related to any glycation that still occurs. Additionally, nuts have high antioxidant capacity (thanks to their concentrations of vitamin E) and are rich in phenolics and flavonoids that fight free radicals.

Cruciferous Vegetables

Cruciferous vegetables contain the powerhouse antioxidant and anti-inflammatory sulforaphane, which is famous not just for giving cabbage and broccoli their distinctive odors, but also for being one of the most effective cancer fighters ever identified.

One of the ways sulforaphane delivers its massive health benefits is by inhibiting AGE-induced damage. In this way, it may prevent cardiovascular and diabetes-related complications. Broccoli sprouts, in particular, may play a protective role against vascular injury by inhibiting the AGEs’ (and their receptors’) axes and exhibiting anti-inflammatory actions.

Citrus

Perhaps the OG antioxidant, and certainly the one with the most publicity, vitamin C lives up to its reputation by helping to inhibit glycation processes. When researchers marinated lean beef in lemon juice for an hour before cooking, it ended up with half the AGEs as the same cut of beef marinated in vinegar.

It’s not just the vitamin C in citrus foods that deserves the credit. Flavonoids such as hesperidin, naringin, and quercetin have anti-inflammatory effects and help reduce the conditions that promote glycation. Hesperidin in particular is being studied for its potential to treat glycation-induced neurotoxicity involved in Alzheimer’s disease.

Citrus fruits also support healthy endothelial function. The endothelium, a layer of cells that lines your blood vessels, can contribute to the development of AGEs when it isn’t working properly, so the support of compounds in citrus fruits can go a long way in keeping glycation in check.

Green Tea

There’s a compound found in green tea called epigallocatechin 3-gallate, which goes by its fun acronym EGCG, which sounds like the name of a trendy dance club from the 1980s (there may be an alternate universe in the multiverse in which I know very little about nutrition and a great deal about house music). EGCG helps protect proteins and other molecules from glycation by neutralizing free radicals before they have the chance to party and form AGEs. In this way, green tea consumption may help prevent neurodegenerative disease.

Through the same pathways, EGCG may also reduce plasma glucose and alleviate complications of diabetes.

AGEs can Age You!

AGEs contribute to a number of health conditions, from skin aging and respiratory disorders to neurodegenerative diseases and cancer. Although AGEs occur naturally as you age, and are found in food and produced in your body, you do have a lot of control over how much you’re exposed to them through diet. By avoiding AGE-forming foods such as animal products and processed foods, you can minimize your intake and protect your body from further harm. You can also reduce your exposure by embracing healthier cooking methods, reducing or eliminating added sugars, and choosing antioxidant-rich plant foods like berries, spices, nuts, cruciferous vegetables, citrus fruits, and green tea.
