Microplastics Found in Human Brain for the First Time

For the first time, researchers have found microplastics in the brain. “Our analysis of olfactory bulbs from deceased patients in São Paulo confirmed the presence of microplastics,” physician and principal investigator Thais Mauad told The Epoch Times. This suggests a potential route for these particles to enter the brain.

Mauad also highlighted the uncertainty surrounding the health effects of these findings. “We still don’t know the consequences,” she said, noting that animal studies suggest potential neurotoxicity and links to neurodegenerative diseases. Plastic does not break down completely; it turns into smaller pieces over time, contaminating the air, food, and water.



Mauad said that people are exposed to more plastics when indoors. “We are massively exposed to microplastics,” she said. “We breathe in more indoors than outdoors.

” Nylon/polyamide: Used in clothing, carpets, and industrial products. Polyethylene: Found in plastic bags, bottles, and containers. Polyethylene vinyl acetate (EVA): Used in flexible packaging and some footwear.

She suspects that the microplastics could enter the brain using the same route. This direct pathway may allow plastic particles to enter the brain without passing through the blood-brain barrier, which acts as a protective shield to prevent the brain from harmful substances. The microplastic particles may be able to interact with the olfactory nerves through this tunnel, she said.

Furthermore, “the presence of non-digestible microplastic particles with additives might provoke reactions,” particularly in a developing brain, she added. Limiting use of plastics: Reduce the use of plastic containers and packaging, especially for food and beverages. Choosing natural fibers: Opt for clothing and textiles made from natural materials rather than synthetic fibers.

Avoid heating plastics: Avoid microwaving food in plastic containers or using plastic wrap in the microwave..
