Detoxing From Microplastics

Micro and nanoplastics (MNPs) have been studied as an environmental issue for a while now (about 20 years) but researchers are only just beginning to truly understand their vast impact on human health. 

In 2022, researchers discovered that MNPs have the ability to break the blood-brain barrier; an animal study published by https://www.mdpi.com/2079-4991/13/8/1404  clickable link (Very long read!) 


Microplastics & the blood-brain barrier

The blood-brain barrier (BBB) is a protective wall that prevents toxins or pathogens from entering the brain. If these unwanted compounds are small enough, however, they can breach the barrier and impact neurological function. 

MNPs ingested from an individual's diet (i.e., via food and water) have been found to break through the BBB. Over time, the presence of these plastic particles can increase inflammation in the brain and even contribute to neurological conditions, such as Alzheimer's and Parkinson's.

 

In the study, researchers orally administered MNPs made of polystyrene (a food-grade plastic used to make Styrofoam takeout containers and meat packaging) to mice via an aqueous solution. They discovered that plastic particles were able to breach the BBB (thanks to a surface structure called a biomolecular corona) and enter mouse brains in just two hours following ingestion. 

 

How to detox from microplastics 

Until further research is conducted outlining the specific health consequences of MNPs in the brain, scientists suggest limiting exposure and restricting usage as much as possible. Avoiding single-use plastic and plastic food packaging is a good place to start. 

Avoid other environmental toxins as well (e.g., heavy metals, harsh chemicals in common household cleaners, pollutants, mold, etc.), as an increased toxic burden makes it more difficult for your detox organs to filter, bind to, and eliminate all unwanted compounds. 

While MNPs cannot be avoided entirely, there are natural ways you can strengthen your body's natural detox pathways on a daily basis—such as...

  • Eating a plant-rich diet with detoxifying herbs and micronutrients
  • Sweating regularly (e.g., through physical activity, sauna usage, and hot baths)
  • Hydrating properly (but remember—tap water has far fewer plastic particles than bottled water!)

You can also consider taking a targeted detoxification supplement that delivers antioxidant ingredients

  • Glutathione
  • Vitamin C
  • Milk thistle 

These can promotes optimal function of your elimination organs (i.e., the liver, kidneys, gut, lungs, skin, and lymph), and further bolsters your body's natural detox pathways.

 

The takeaway

 

Micro- and nanoplastics can wreak havoc on the body, including the brain. While avoiding them entirely is virtually impossible, incorporating daily detoxification methods into your well-being routine can help support your liver and other elimination organs to rid yourself of MNPs and other unwanted toxins.
