Microplastics linked to higher dementia risks in brain

A new study reveals that the human brain contains about a teaspoon of microplastics and nanoplastics, with levels three to five times higher in individuals with dementia. This finding raises concerns about the potential health impacts of plastic consumption. Researchers found that microplastics in the brain are significantly more concentrated than in other organs. Participants with dementia had up to ten times more microplastics compared to those without the condition, indicating a possible link between plastic exposure and brain health. The study highlights that bottled water, air, and seafood are major sources of microplastics. It suggests that switching from bottled to tap water could greatly reduce microplastic intake. Additionally, using non-plastic food storage options and avoiding heating food in plastic containers may help minimize exposure.
