We are not just polluting the planet with plastic.
We are absorbing it.
Microplastics and nanoplastics are no longer just an environmental issue.
They are a human biology issue.
They’ve been detected in:
Brain tissue
Lungs
Blood
Testicles
Ovaries
Placentas
Breast milk
Even a baby’s first stool
In 2025, researchers from the University of New Mexico reported measurable plastic particles in human brain samples, with higher concentrations observed in individuals with neurodegenerative disease.
The average human brain now contains 7 grams of plastic (!!!), which is roughly the weight of a disposable plastic spoon or five water bottle caps.
Let that sink in.
We are now the filter for a plastic-saturated world.
So, Where Is It Coming From?
It’s not just coming from ocean waste or bottled water.
Microplastics are generated when larger plastics break down over time, including plastic waste produced decades ago.
These particles fragment into microscopic and even nano-sized pieces small enough to circulate through the bloodstream.
They’re in:
Bottled and tap water
Indoor air and dust
Ultra-processed and packaged foods
Synthetic clothing and carpets
Non-stick cookware
Personal care products
Food storage containers
Even if plastic production stopped today, environmental breakdown would continue releasing particles for decades.
Why This Matters For Health
Micro- and nanoplastics are being studied for their role in:
Hormone disruption
Increased oxidative stress
Immune dysregulation
Inflammatory signaling
Potential impacts on fertility
Neuroinflammation
We’re still very early in understanding long-term consequences.
But, we already know this:
The total toxic load on the human body has never been higher.
And, detox isn’t about trends. It’s about your biological capacity.
You Can’t Avoid It All, But You Can Lower Your Load
We cannot fully eliminate plastic exposure.
But, we can meaningfully reduce incoming burden through small, strategic daily swaps.
So, here are 20 high-impact, realistic ways to reduce your exposure starting today.
Eat more real, whole foods—less packaged, less processed.
Stick to fresh, organic produce and unrefined ingredients to minimize exposure to additives, preservatives, chemicals, and other hidden toxins. Shop the perimeter of the grocery store and cook at home as much as possible.
Swap plastic cookware, utensils, and dishware.
Non-stick and aluminum pans often contain PFAS—“forever chemicals”—linked to hormone disruption, inflammation, and metabolic dysfunction. When heated, they can leach into your food, making their way into your body. Opt for wood, bamboo, ceramic, cast iron, or stainless steel instead. I use Xtrema ceramic (MEGHAN15 for 15% off) and/or Lodge cast iron cookware. I also use the Vitamix Stainless Steel Container. Read more about other great non-toxic kitchen swaps here.
Use glass storage containers.
Ditch plastic Tupperware and water bottles, especially if you’re storing anything hot or acidic. Opt for glass jars (like classic Mason jars or even these containers), stainless steel containers, or high-quality silicone (like Stasher food storage bags) for travel. Read more about other great non-toxic kitchen swaps here.
Ditch bottled water.
Most bottled water is just glorified tap water in plastic. Buy spring or mineral water in glass bottles from a trusted source like Alive Water (MEGHAN15 for 15% off) or Mountain Valley Spring Water, or choose a high-quality reverse osmosis filter with a glass carafe like AquaTru instead (discount applied at checkout). What you drink becomes what your cells bathe in. Read more about the importance of water quality here.
Filter your air.
Indoor air is often more polluted than outdoor air due to VOCs from furniture, cleaning products, and artificial fragrances. I use an AirDoctor (discount applied at checkout) in every single room of my house. Clean air leads to a lighter toxic load. Read more about the importance of air quality here.
Wash your hands before meals.
Microplastics and toxins from steering wheels, keyboards, and door handles can end up in your food. A simple 20-second wash goes a long way.
Cut back on synthetic clothing.
Polyester, nylon, and spandex shed microplastics into the air and through your skin. Choose organic cotton, linen, wool, or hemp whenever possible. Read more about what to wear (both brands and fabrics) here.
Go plastic-free with food and drinks.
Choose unpackaged produce and skip plastic-lined coffee cups, especially for hot drinks. Bring your own mug, like this 32 oz MiiR wide mouth water bottle I bring with me everywhere.
Avoid thermal paper receipts.
Receipts often contain BPA/BPS and shed microplastics. Say no when possible, choose digital receipts, and wipe down surfaces where dust settles.
Choose natural fiber furnishings and bedding.
Synthetic materials shed microplastics into household dust. Opt for organic cotton, linen, wool, or hemp. I love Parachute Home bedding and also swear by my Birch Living Luxe Natural Mattress, Plush Organic Mattress Topper, and Organic Pillows (MEGHAN25 for 25% off).
Install a shower filter.
Tap water can contain microplastics and other contaminants. A simple shower filter helps reduce direct skin exposure and inhalation while showering. Try Pristine Hydro, Rorra, AquaTru (discount applied at checkout), Vitaclean (MEGHAN10 for 10% off), or Jolie.
Vacuum and dust regularly with a HEPA filter.
Microplastics accumulate in household dust from clothing, furniture, packaging, and flooring. Regular HEPA vacuuming and wiping surfaces with a damp cloth helps reduce what you inhale and ingest. I have this Dyson cordless vacuum, but you can also check out this one or this one. Read more about this here.
Ditch synthetic sponges and scrubbers.
Most kitchen sponges are plastic-based and shed microplastics every time you wash dishes. Switch to cellulose sponges, natural fiber brushes, or compostable scrubbers. I love these Blueland sponges.
Be mindful of tea bags and coffee pods.
Many commercial tea bags and single-use coffee pods are made of plastic that releases microplastics when exposed to hot water. Opt for loose-leaf tea (I adore Magic Hour) and reusable coffee filters or stainless steel pods. I personally ditched coffee and now drink ceremonial cacao every day.Avoid synthetic dryer sheets.
Dryer sheets are made from and coated with plastic polymers that can shed microplastics and deposit residues on your clothes. Choose wool dryer balls (like these) instead.Rethink flooring and furniture.
Vinyl flooring, synthetic rugs, and foam-filled furniture can shed significant microplastics into indoor air and dust. Opt for natural materials like wool rugs, solid wood, and untreated natural fibers whenever possible.Skip single-use packaging.
Pre-cut fruits and veggies, salad kits, and grab-and-go meals are often wrapped in thin, low-grade plastics that easily shed particles. Whole, unpackaged produce drastically cuts exposure. This is one of the reasons I love going to the farmer’s market every Sunday when I’m home in Los Angeles.Limit synthetic textiles in your home.
Beyond clothing, microfiber blankets, fleece, and polyester upholstery are major indoor sources of microplastic dust. Natural fiber fabrics shed less and are better for indoor air quality.
Wash synthetic clothes less frequently (and smarter).
When you do wash synthetics, use a microplastic filter or wash bag to trap particles before they enter waterways. Cold, gentle cycles reduce shedding too.Absolutely don’t microwave plastic (or don’t microwave at all).
Even “BPA-free” plastics can leach micro- and nanoplastics when heated. Always transfer food to glass or ceramic before reheating.
You can’t eliminate every plastic particle.
But, you can:
Lower incoming exposure
Strengthen elimination
Reduce cumulative toxic load
Improve resilience
And, that matters, especially when it comes to fertility, cognitive health, hormonal balance, chronic disease prevention, and long-term health and well-being.
Now, Let’s Talk About The Other Side of Detox
Reducing exposure is step one.
Step two is ensuring your detox pathways are actually functioning properly.
Because plastic particles don’t leave through willpower.
They leave through biology.
Your body eliminates through:
The liver (phase I & II detoxification)
Bile flow
The gut (elimination)
The skin (sweat)
The lymphatic system (movement)
The kidneys (urine)
If those pathways are sluggish, toxins recirculate.
This is why I structure detox in the body’s correct biological sequence when I work 1:1 with clients:
Open drainage pathways.
Optimize bowel function.
Support liver processing.
Then, mobilize deeper stored burden (parasites, pathogens, mold, heavy metals).

Hi!! This is so incredibly informative but I work in regulation (chemical regulation and product safety) and I can confirm you don’t need to be scared of receipts! I’m not entirely sure about what the FDA says but UK and EU regulations stop these harmful ingredients from hitting the market :) FDA, UK and EU are generally harmonised so I am **assuming** that they are safe in the US.
