A new study conducted by researchers at the University of New Mexico found that the average human brain may contain small plastic particles, with the highest amounts found in those with dementia. The study, published in Nature Medicine, showed that by 2024, the average human brain contained the equivalent of one plastic spoonful, about 7 grams worth. The concentrations of microplastics in brains were higher compared to livers and kidneys, and there was a higher concentration in brains of individuals with dementia.
Researchers believe that the increase in plastic exposure in humans may be behind the rise in plastic particles found in the brain. The particles are believed to enter the body through ingestion, inhalation, or consumption. The small size of the particles allows them to enter the body and potentially accumulate in organs like the brain.
While the presence of plastic in the brain is concerning, it is still unclear whether it poses significant health risks. The researchers found that the amount of plastic in the brain was not significantly different between older and younger individuals, suggesting that the body may clear these particles over time. However, more research is needed to understand the potential implications of plastic particles in the brain.
It is important to note that children and older individuals may be at higher risk due to differences in brain protection mechanisms. Despite the findings, experts recommend not making drastic lifestyle changes to avoid plastic exposure until more is known about the potential risks. Further research is needed to investigate the sources of plastic exposure and its effects on human health.
