Episode description
Story at-a-glance
- Research shows microplastics become trapped in brain blood vessels when consumed by immune cells, leading to reduced blood flow and impaired cognitive function in mice
- Human brain tissue contains seven to 30 times more microplastic contamination than other organs, with particularly high concentrations found in individuals diagnosed with dementia
- Researchers identified a direct pathway for microplastics to enter your brain through your nose, bypassing the blood-brain barrier via the olfactory system
- Polypropylene, a common plastic used in packaging and consumer goods, was found in over 40% of brain tissue samples, highlighting the impact of everyday plastic exposure
- Practical solutions such as water filtration, choosing natural fiber clothing and using non-plastic food packaging help reduce your microplastic exposure
