A shocking new study has claimed that the human brain is becoming contaminated with growing amounts of microplastics, with concentrations skyrocketing in just the past few years. However, some have cast doubts on the study's underlying methods.
The research, published Feb. 3 in the journal Nature Medicine, found that concentrations of tiny micro and nanoplastics in healthy human brain tissue rose by roughly 50% between 2016 and 2024. The analysis also found that the plastic concentration in people who died with dementia was even higher — about six times higher than that seen in healthy brains.
