Plastic Isn’t Just a Pollution Problem—It’s a Health Crisis
by Mark J Kaylor
Microplastics have infiltrated nearly every part of our environment, from the food we eat to the air we breathe. While research into their long-term health effects is still in its early stages, evidence suggests that these tiny plastic particles can accumulate in human tissues, potentially leading to oxidative stress, inflammation, and various health complications. Given the ubiquity of microplastics, the question arises: can we actively support our body’s ability to eliminate them? While there is no single method to remove microplastics from the body, emerging research suggests that optimizing detoxification pathways, supporting gut and lung health, and minimizing exposure can make a significant difference.
What Are Microplastics?
Microplastics are tiny plastic particles measuring less than 5 millimeters in size, often invisible to the naked eye. They originate from the breakdown of larger plastic waste (secondary microplastics) or are intentionally manufactured at small sizes for use in cosmetics, industrial processes, and synthetic textiles (primary microplastics). These particles are highly persistent in the environment and can absorb toxic chemicals, making them a growing concern for human health and ecosystems. Due to their minuscule size, microplastics have been found in oceans, soil, drinking water, food, and even the air we breathe.
Understanding Microplastic Exposure
Microplastics enter our bodies primarily through three main routes:
- Ingestion – Microplastics are found in food, drinking water, and even salt. Processed and packaged foods are particularly vulnerable to contamination. Studies have found microplastics in seafood, fruits, vegetables, and even honey and beer.
- Inhalation – Airborne microplastics, particularly from synthetic clothing, carpets, and urban pollution, accumulate in our lungs and bloodstream.
- Dermal Absorption – Although less studied, microplastics may penetrate the skin through cosmetics, lotions, and personal care products that contain plastic-derived ingredients.
Researchers have detected microplastics in human lungs, liver, kidneys, and even the brain. A study published in Nature Medicine found increasing levels of microplastics in brain tissues over the last decade. Another study revealed microplastics in 80% of lung samples examined. Given their ability to persist in our bodies, it is crucial to take proactive steps to limit their impact.
Microplastics in the Brain: A Growing Concern
Recent studies have shown that microplastics can cross the blood-brain barrier, a protective shield that prevents harmful substances from entering the brain. This discovery raises significant concerns about potential neurological effects, including cognitive decline, neuroinflammation, and increased oxidative stress in the brain.
- How Microplastics Enter the Brain:
- Inhalation and Circulatory Transport – Once microplastics enter the bloodstream via the lungs, they may travel to the brain and accumulate in neural tissue.
- Gastrointestinal Absorption – Ingested microplastics may cross the gut barrier and enter systemic circulation, eventually reaching the brain.
- Nasal Inhalation and Olfactory Pathway – Some microplastics may bypass the blood-brain barrier entirely by traveling through the olfactory nerves, directly affecting brain tissue.
- Potential Brain Health Effects:
- Increased neuroinflammation (linked to neurodegenerative diseases like Alzheimer’s and Parkinson’s).
- Increased oxidative stress and mitochondrial dysfunction.
- Potential disruption of neurotransmitter function, affecting mood, memory, and cognition.
- Protecting Brain Health from Microplastic Exposure:
- Antioxidants such as Curcumin, Resveratrol, and Ergothioneine to reduce oxidative stress.
- Omega-3 Fatty Acids from fish oil and flaxseeds to support brain cell integrity.
- Sulforaphane (from broccoli sprouts) to enhance detoxification pathways in the brain.
How to Reduce Microplastic Accumulation in the Body
1. Support Gut Health for Elimination
The digestive tract serves as a primary pathway for excreting microplastics. Optimizing gut health may enhance the body’s ability to expel them efficiently.
- Increase Dietary Fiber – Fiber binds to waste materials and promotes excretion. Best sources include:
- Psyllium husk
- Flaxseeds & chia seeds
- Oat bran & leafy greens
- Consume Fermented Foods – A robust microbiome may help degrade microplastics. Beneficial sources include:
- Sauerkraut
- Kimchi
- Kefir & yogurt
- Use Natural Binders – Certain compounds may help trap and remove microplastics:
- Activated Charcoal & Bentonite Clay – Bind to toxins and plastic particles in the gut.
- Chlorella & Spirulina – Known for their detoxifying properties against heavy metals and pollutants.
2. Enhance Liver Detoxification
The liver is a crucial detoxification organ, helping to break down and eliminate harmful substances, including plastic-derived chemicals.
- Boost Glutathione Levels – This antioxidant is essential for detoxification. Increase levels through:
- N-Acetylcysteine (NAC) – A powerful precursor to glutathione, NAC helps protect the liver from oxidative stress and supports toxin breakdown.
- Alpha-lipoic acid (ALA) – A potent antioxidant that regenerates glutathione and supports detoxification by reducing oxidative damage in the liver.
- Milk thistle – Contains silymarin, which has been shown to support liver function, promote detoxification, and protect against environmental toxins.
- Eat Cruciferous Vegetables – Support liver detox pathways with:
- Broccoli
- Brussels sprouts
- Watercress
- Promote Bile Flow – Bile helps remove fat-soluble toxins. Enhance bile production with:
- Beets
- Dandelion root tea
- Turmeric
3. Reduce Overall Exposure to Microplastics
Prevention is just as important as elimination. Limit exposure by:
- Switch to Glass or Stainless Steel for Food Storage – Avoid plastic containers and bottles, especially for hot foods and liquids.
- Filter Drinking Water – Use reverse osmosis or activated carbon filters to remove microplastics from tap water.
- Never Microwave in Plastic – Heating plastic containers releases microplastic particles and harmful chemicals such as phthalates and bisphenol A (BPA), which can leach into food. Instead, use glass, ceramic, or stainless steel containers when reheating food.
- Reduce Use of Synthetic Textiles – Polyester, nylon, and acrylic shed microplastics; opt for organic cotton, wool, or hemp. Wash synthetic clothes in a microplastic-catching bag like the Guppyfriend.
- Avoid Ultra-Processed Foods – Packaging materials may leach microplastics into food. Fresh, whole foods are the safest option.
- Choose Natural Personal Care Products – Many cosmetics, toothpaste, and lotions contain plastic-derived ingredients. Opt for brands that avoid microplastics.
- Use HEPA Air Filters in Your Home – Helps reduce airborne plastic particles from carpets, textiles, and household dust.
- Avoid Plastic Kitchen Utensils and Cookware – Plastic spatulas, cutting boards, and non-stick cookware may introduce microplastics into food. Choose wood, stainless steel, or cast iron alternatives.
- Be Mindful of Tea Bags and Coffee Pods – Many tea bags and coffee pods contain plastic fibers that release microplastics when exposed to hot water. Use loose-leaf tea and stainless steel or glass coffee brewers.
- Reduce Single-Use Plastics – Straws, plastic wrap, takeout containers, and disposable cutlery contribute to microplastic pollution. Bring reusable alternatives when possible.
By making these changes, you can significantly lower your exposure to microplastics and lessen their accumulation in your body.
