A recent study found that humans tend to have higher concentrations of microplastics in their brains compared to other bodily organs. Researchers analyzed post-mortem brain tissue samples from 2016 to 2024 and discovered that people with dementia had up to 10 times more microplastics present in their brains than those without the condition.
The study, led by researchers at the University of New Mexico, used a special method to identify 12 different polymers in brain tissue samples. The findings suggest that the brain may be uniquely vulnerable to micro- and nanoplastic accumulation due to its high metabolism and lipid-rich composition.
However, the study also found an absence of higher concentrations in older individuals, suggesting that the human body may be able to eliminate or excrete these particles over time. This suggests that reducing exposure could directly impact microplastic accumulation in the body.
The researchers emphasize the need for further research to understand the relationship between microplastics and neurological conditions. While the study highlights the importance of effective environmental policies, it also raises questions about the potential origins of microplastics in the brain.
To protect their bodies and brains from microplastics, experts recommend cutting back on plastic use when possible, avoiding single-use plastics, and opting for filtered tap water instead of bottled water. They also suggest focusing on good sources of food, reducing ultra-processed foods, wearing natural fiber clothing, and maintaining good air ventilation systems in homes and workplaces.
