I got into this whole space after watching The Plastic Detox documentary. I already cared about seed oils and clean eating, but that film showed me a layer I hadn't really thought about — the plastic itself. Not just the environmental angle, but what these materials are doing inside our bodies, at a molecular level, every single day.
Since then I've gone pretty deep on the research. And honestly? The more I learn, the more I think most people have no idea how much microplastics they're consuming — or what it's doing to them. So let's walk through it. No panic, no selling you a detox kit. Just the information.
What Are Microplastics and How Do They Get in Your Body?
Microplastics are tiny plastic fragments — smaller than 5mm, often microscopic — that break off from larger plastic products. They come from food packaging, synthetic clothing fibers, water bottles, cosmetics, dust, and dozens of other sources. Nanoplastics are even smaller: small enough to cross cell membranes and the blood-brain barrier.
You're exposed through three main routes:
- Ingestion — eating and drinking from plastic containers, eating food wrapped in plastic, consuming seafood that has absorbed plastics
- Inhalation — breathing in microfibers from synthetic carpets, clothing, and household dust
- Skin contact — cosmetics, synthetic fabrics, and personal care products containing plastic-derived ingredients
Studies estimate the average person ingests about a credit card's worth of plastic per week. That number gets debated, but even conservative estimates put it at several grams per month. It's not zero, and it's not trivial.
What Are the Symptoms of Having Microplastics in Your Body?
This is where people want clean answers, and honestly, the science is still catching up. But here's what researchers are finding:
Microplastics in body effects that have been documented or strongly suggested in peer-reviewed research include:
- Gut inflammation and disrupted gut microbiome — microplastics physically irritate the gut lining and alter bacterial populations
- Endocrine disruption — chemicals that leach from plastics (BPA, phthalates, PFAS) mimic or block hormones, especially estrogen
- Oxidative stress — the body's inflammatory response to foreign particles it can't break down
- Reproductive issues — multiple studies link plastic chemical exposure to lower sperm counts, disrupted cycles, and fertility challenges
- Cardiovascular concerns — a 2024 study in the New England Journal of Medicine found microplastics in arterial plaque, with higher levels correlated to increased heart attack and stroke risk
The tricky part: there's no "microplastic poisoning" diagnosis. The symptoms of having microplastics in your body overlap with a ton of other conditions — fatigue, brain fog, unexplained inflammation, hormonal imbalances, digestive issues. You can't point to one symptom and say "that's the plastic." But when you zoom out and look at population-level data, the correlations are hard to dismiss.
Do Microplastics in the Body Go Away?
Partially. Your body can eliminate some microplastics through normal metabolic processes — sweating, urination, and bowel movements clear a portion of what you ingest. But nanoplastics that have crossed into tissue, organs, and the bloodstream are a different story. They accumulate. Researchers have found microplastics in lung tissue, liver, kidney, placenta, and brain tissue in autopsies.
So can you clean plastic out of your body? You can reduce the incoming load and support your body's natural elimination. You can't do a three-day juice cleanse and flush it all. Anyone selling you a "microplastic detox" product is oversimplifying. The real plastic detox is about reducing exposure over time, not a one-time purge.
How to Reduce Microplastics in Your Body
If you're wondering how to remove microplastics from your body naturally, the honest answer is: reduce what's coming in, and support what's going out. Here's what the research and common sense actually support:
1. Fix Your Food Exposure First
Microplastics in food are the primary source for most people. The biggest offenders:
- Bottled water — one study found bottled water contains up to 100x more nanoplastics than previously estimated. This is probably the drink with the most microplastics by volume for most people. Switch to filtered tap water in glass or stainless steel.
- Seafood — shellfish and small fish accumulate microplastics from ocean pollution. They're among the foods that contain the most microplastics.
- Takeout containers — hot food in plastic or styrofoam containers leaches significantly more plastic than cold food. Ask for no plastic lid, bring your own container if you can.
- Tea bags — many brands use plastic mesh bags that release billions of microplastic particles per cup when steeped in hot water. Loose leaf tea or paper-only bags are the move.
- Plastic-wrapped produce — especially when stored long-term or exposed to heat during transport.
Is coffee full of microplastics? It depends. Paper-filtered drip coffee is relatively clean. But single-serve plastic pods (K-cups) and coffee-to-go lids are significant sources. If you're a daily coffee drinker, switch to a French press, pour-over with paper filters, or a stainless steel moka pot. Skip the plastic lid.
Are eggs high in microplastics? Research on this is emerging. Free-range eggs can pick up microplastics from soil and feed contamination, but eggs are generally lower-exposure compared to seafood, bottled water, and heavily packaged foods. Not zero, but not the main concern.
2. Eat Foods That Help Your Body Deal with It
People ask what foods remove plastic from the body — and while no food literally dissolves plastic, certain foods support the detoxification pathways that help your body process and eliminate foreign particles:
- Cruciferous vegetables (broccoli, cauliflower, Brussels sprouts) — support liver detox pathways, particularly phase II detoxification
- High-fiber foods — bind to toxins in the gut and help move them out. Think whole grains, legumes, and leafy greens.
- Berries and citrus fruits — when people ask what fruit removes microplastics, the answer is really about antioxidants. Berries are loaded with polyphenols that combat oxidative stress caused by plastic exposure.
- Fermented foods — kimchi, sauerkraut, yogurt. Support the gut microbiome that gets disrupted by microplastic exposure.
- Garlic and onions — sulfur compounds support glutathione production, your body's master antioxidant.
What to drink to avoid microplastics? Filtered water from a glass or stainless steel bottle. Loose leaf tea. Coffee from a non-plastic brewer. Fresh-squeezed juice if you're feeling fancy. Avoid anything in a plastic bottle, especially if it's been sitting in heat.
3. Consider Targeted Supplements
For people asking what supplements remove plastic from the body — again, nothing literally removes embedded plastic. But certain supplements support the detox pathways that deal with plastic-associated chemicals:
- NAC (N-Acetyl Cysteine) — precursor to glutathione, your body's primary detoxifier
- Chlorella — binds to heavy metals and certain toxins in the gut
- Activated charcoal — used sparingly, can bind toxins in the digestive tract (don't take it daily or with medications)
- Sulforaphane (from broccoli sprout extract) — one of the most studied compounds for upregulating detox enzymes
- Probiotics — help restore gut bacteria disrupted by microplastic exposure
We list clean supplement brands in our non-toxic products directory if you want options that aren't loaded with fillers and additives themselves.
4. Reduce Ongoing Exposure
How to avoid microplastics in food and daily life comes down to practical swaps:
- Store food in glass or stainless steel, not plastic
- Never microwave food in plastic containers
- Use a water filter that catches microplastics (reverse osmosis is the gold standard)
- Switch from plastic cutting boards to wood or bamboo
- Swap Ziploc bags for silicone or beeswax wraps
- Buy loose produce, not plastic-wrapped
Can you avoid eating microplastics entirely? Honestly, no. They're in the air, the water, the soil. But you can cut your exposure dramatically — some estimates suggest 70-80% — by making the swaps above. That's the realistic version of a plastic detox.

What About "Microplastics in Food Health Risks"?
Let's be straight about where the science stands. Microplastics in food health risks are being studied aggressively right now, but we're still early. What we know:
- Animal studies show clear links between microplastic ingestion and gut inflammation, liver damage, and reproductive harm
- Human epidemiological studies show correlations between plastic chemical exposure (measured via urine BPA/phthalate levels) and metabolic disease, infertility, and cardiovascular issues
- The NEJM arterial plaque study in 2024 was one of the first direct human studies linking plastic presence in tissue to clinical outcomes
Is it "proven" in the way pharmaceutical studies prove things? Not yet. But the direction of the evidence is consistent and concerning. The precautionary principle applies here the same way it does with seed oils — when the risk is plausible and the alternatives are available, why not switch?
What Breaks Down Plastic in the Body?
This is a question people search a lot: what dissolves plastic in the body? or what breaks down plastic in the body?
The short answer: your body can't break down plastic the way it breaks down food. Plastics are synthetic polymers that resist biological degradation — that's literally their selling point as materials. Your immune system treats them as foreign bodies, triggers inflammation, and tries to wall them off. Small particles can be excreted; larger or embedded ones stay.
Some emerging research is looking at certain enzymes (like PETase) that can degrade plastics, but that's environmental science, not something happening inside your body. For now, how do you flush plastic out of your body? You support elimination (sweat, fiber, hydration) and you stop adding more. That's the honest answer.
The Bottom Line
Microplastics are real, they're in all of us, and the health implications are looking worse the more we study them. But the answer isn't panic — it's practical change. Fix the biggest sources first (bottled water, food storage, heating food in plastic), support your body's natural detox pathways, and gradually swap to plastic-free products where you can.
The fact that you're reading this means you're already ahead of most people. Start with the food and kitchen — that's where the exposure is highest and the swaps are easiest. Our guide on going plastic free at home walks through exactly how to do it.
