Recent research has found that an adult human brain contains microplastics equivalent to the weight of a disposable plastic spoon. These tiny plastic particles, which come from sources like food packaging, bottled water, and even the air we breathe, are accumulating at alarming rates. Between 2016 and 2024, microplastic levels in human brains surged by 50%. The concentrations are particularly high in people diagnosed with dementia, raising serious concerns about their potential health effects.

 How to Reduce Microplastic Exposure

Microplastics enter the brain through common sources like bottled water, plastic food containers, and even tea bags. Switching to filtered tap water, using glass or stainless steel containers, and avoiding ultra-processed foods can help reduce exposure. HEPA air filters may also limit inhaled microplastics.

Can We Remove Microplastics from Our Brains?

Scientists are still unsure how the body clears out microplastics, but some research suggests they might be expelled through sweat, urine, or feces. More studies are needed to determine effective ways to remove them. In the meantime, experts urge people to limit their exposure as much as possible.
