New research reveals how anthocyanin-rich fruits and vegetables could help defend your body against toxic microplastic exposure.
If it seems like a weekly occurrence that a new microplastic-filled product is potentially harming your health, you’re right. Between tea bags, lipstick, dishwasher detergent, and gum (among many other things), it’s hard to avoid these tiny toxic particles. But there’s a glimmer of good news: a study published in the Journal of Pharmaceutical Analysis found that colorful fruits and vegetables may combat the negative effects of microplastics in the body.
Fruits and vegetables are known for their abundant vitamins and minerals, but the study examined how anthocyanins — natural compounds found in colorful fruits and vegetables — may protect the reproductive systems from microplastic damage. Specifically, researchers explored how anthocyanins interact with steroid receptors (protein molecules within a cell that bind to hormones such as estrogen, progesterone, and testosterone) which play essential roles in reproductive health, says Angelo Falcone, MD, an integrative medicine physician and founder of Dignity Integrative Health and Wellness. “This isn’t an original research study with experiments, but rather a comprehensive review of existing literature because the study authors looked at how microplastics disrupt our endocrine system and harm reproductive health, then assessed how anthocyanins might counteract these effects through their antioxidant and anti-inflammatory properties.”
What’s particularly striking about this research is how it represents an intersection of environmental and nutritional medicine. “We can’t completely avoid microplastic exposure in today’s world since they’re in our food, water, and air, but we can harness the protective power of colorful plant foods as part of our defense strategy,” Falcone says.
So which fruits and veggies help fight microplastics — and how, exactly, do they do it? Here’s what doctors want you to know.
What are anthocyanins?
Anthocyanins are natural pigments that give fruits and vegetables their vibrant red, purple, and blue color, says Falcone. “There are over 700 varieties, but anthocyanins are a type of flavonoid (a group of compounds known for antioxidant properties) found in foods like blueberries, blackberries, red cabbage, and purple corn.”
These compounds aren’t just responsible for beautiful colors — they’re also biologically active molecules that interact with various systems in the body to promote overall health. “Anthocyanins are among the most potent natural antioxidants we can consume through food because they neutralize harmful free radicals in the body, helping to reduce oxidative stress that can damage cells, proteins, and DNA,” Falcone explains.
Furthermore, due to the powerful antioxidant properties of anthocyanins, they are recognized for their ability to protect the body from inflammation and various stress-related conditions, such as heart disease, neurodegenerative disorders, and cancer, which would otherwise be caused by free radicals, says Nicholas Church, MD, a family medicine physician and founder of Somerset Medical.
How do anthocyanins in fruits and vegetables counteract the adverse effects of microplastics? First, a microplastics primer: Scientists are still exploring exactly how microplastics interact with the human body, but at a basic level, the toxic properties trigger inflammation and oxidative stress, which are both responsible for damaging cells and tissues.
Microplastics also function as endocrine disruptors, interfering with hormonal systems that regulate reproduction, metabolism, and development. “Most concerning, though, is microplastic’s ability to cross protective barriers in our body, including the blood-testis barrier and placental barrier, allowing them to accumulate in reproductive organs, where they can directly damage reproductive cells and interfere with normal fertility and development,” says Falcone.
Your Tea Bag Is Likely Releasing Billions of Microplastic Particles, According to a New Study Fortunately, anthocyanins operate through several mechanisms to protect against microplastic damage. First and foremost, anthocyanins are potent antioxidants, meaning they neutralize the oxidative stress that occurs when microplastics enter the body, thereby minimizing the risk of cellular damage, Falcone says. They also reduce microplastic-induced inflammation, ultimately lowering the risk of gastrointestinal issues, cancer, and organ damage, Church adds.
Additionally, anthocyanins may interact with steroid receptors to regulate hormone functions that microplastics can disrupt, according to Falcone. “Essentially, anthocyanins provide a multilayered defense system against microplastics.”
Which foods are rich in anthocyanins?
The richest sources of anthocyanins are deeply colored fruits and vegetables. “Berries are superstars, particularly blueberries, blackberries, cranberries, raspberries, and bilberries, but other excellent sources include black rice, purple corn, red cabbage, purple sweet potatoes, red grapes, pomegranates, and açai berries,” Falcone says. “The general rule is, the deeper and more vibrant the purple, blue, or red color, the higher the anthocyanin content.”
It’s also worth noting that every colorful fruit and vegetable contains slightly different types of anthocyanins, each providing its own unique health benefit, so Falcone says it’s important to eat the rainbow.
How Microplastics Sneak Into Your Food — and What You Can Do About It Now, as for the quantity of anthocyanins you should consume to enjoy their benefits, there is no standardized recommendation. However, research suggests aiming for 50 milligrams of anthocyanins per day may assist in reducing oxidative stress. According to Falcone, that translates to roughly one cup of blueberries or half a cup of blackberries.
Just remember that consistency is key. “The benefits of anthocyanins tend to be cumulative, so long-term, consistent intake (weeks to months) is necessary to see measurable effects on combating the damage from microplastics,” Church says. “Think of anthocyanins as an ongoing protective strategy rather than a one-time remedy,” adds Falcone.
What are the additional health benefits of anthocyanins?
Beyond their role in combating microplastics, studies suggest that anthocyanins support heart health by enhancing blood vessel function and reducing inflammation. They also show promise in promoting brain health, potentially delaying cognitive decline. Some research even indicates that anthocyanins may reduce the risk of skin cancer, colorectal cancer, and chronic obstructive pulmonary disease.
On top of that, the powerful compound supports reproductive health in both men and women, with recent research indicating that they balance hormone levels and protect reproductive organs from oxidative damage. “In men, certain anthocyanins appear to safeguard testicular tissue and maintain healthy testosterone production, and in women, anthocyanins may help protect ovarian function,” Falcone says. “What’s fascinating, though, is how anthocyanins seem to modulate steroid receptors — the cellular components that respond to reproductive hormones — helping maintain proper hormonal signaling.”
How else can you counteract the harmful effects of microplastics? Beyond consuming anthocyanin-rich foods, Falcone and Church suggest the following to reduce microplastic exposure and counteract their effects:
Eat a balanced diet. Fiber-rich foods (like berries, lentils, apples, sweet potatoes, chia seeds, and walnuts) and cruciferous vegetables (like broccoli, cabbage, cauliflower, and kale) bind to the digestive tract and boost liver detoxification to reduce microplastic toxicity. Probiotics in kimchi, miso, tempeh, and kefir also help maintain a healthy gut and reduce the presence of harmful chemicals.

YW
Berries; Blueberry, Viking Aronia, Black Raspberry, Blackberry etc
Why does it always have to be vegetables?
This is berries, actually
I quit chewing gum once I heard about microplastics.
Is that right next to your sock drawer?
Oh, thanks. Things are looking up. Now I can go back to doing taxes
Thanks.
Not fond of most of these foods, though often have yogurt with fruit for dessert.
Kombucha contains probiotics. I drink a lot of it, favorite flavor is Mojita, because it’s not sweet. Tastes a lot like a Mohito. 0.06% alcohol. My friend who leads largest daily AA group in the city likes it, says that much alcohol isn’t enough to hurt him.
Pomegranate juice is dark purple and delicious. It should of course be kept in glass bottles and always refrigerated. I get mine at Walmart, where they have the best in town.
We just saw a week ago that there was an article stating carrots and apples were really bad. Loaded with micro-plastics.
Never know which study to believe. I think every one is suspect. Unless it agrees with my own preconceived notions of right or wrong.
Well, we need a lot more research, that is for sure.
Will let you know when I get the results. My cellular health is excellent and I only started eating blueberries. :) So if the main toxicity of Micro/nano plastics is induction of oxidative stress anything to reduce that should help. The vast majority of plastics from what I understand are excreted in any case (which the Millionmarker test for chemicals in urine is expected to test).
The problem has been known about for years but on a more positive note the research at last is starting to follow.
We harvest GALLONS of wild Black Cap Raspberries each summer - sometimes Blackberries too, if we’re lucky. I freeze them, loose, on cookie sheets, then bag them and keep them frozen.
We eat them nearly every day on yogurt or cottage cheese.
I Picked 3 gallons of viking aronia, all frozen. Lots of antioxidants, but its not a really a tasty out of hand type of berry. I cut them up and use it to brew hot ginger / green tea.
The children are all grown and I have not been to the U-Pick blueberry patch in a number of years. The owner passed and I do not know if the Mrs. will continue the running the patch. I think that I will go this year and get 10 or 15 pounds to freeze if she is open.
Pomegranate juice is good stuff, I agree.
While I enjoy juice as a beverage, a lot of the flavonoids, phenols, and polyphenols at issue are frequently in the pulp and also require such high dosages to be effective that dried fruit is a more realistic option, or supplements that take out the sugar and just leave the bio active substances.
I have no clue if pomegranate juice keeps the good stuff. Hope it does.
Long way of saying, whole fruit, dried fruit, and supplements is the safe way to go for health benefits.
I try to take supplements by color, believe it or not: green (broccoli, olive leaf, whatever), red (lycopene), yellow (quercetin, cumin), white (spermatin, fistein, hesperin, blue/purple (berries, reveretol), plus Vitamin D and C and zinc/magnesium. Then high dosage fish oil and a couple others.
The above is not comprehensive. I vary my groupings, sticking to the color scheme.
Collagen of various kinds, but that’s because I’m a power lifter and my joints get banged up. Plus I don’t like dark bird meat.
Creatinine, too.
In top of that I eat a healthy diet heavy on protein and veggies and fiber.
My numbers and health are great. Look like I’m in my 30s, when I’m an old Gen X, banged up Iraq vet. My grey hair even partially went back to black.
