A recent study from the University of New Mexico has revealed that the average human brain contains approximately 7 grams of microplastics—the equivalent weight of a plastic spoon. Alarmingly, the concentration of these tiny plastic particles in the brain has surged significantly between 2016 and 2024, with the highest levels observed in individuals diagnosed with dementia.
While microplastics were also detected in the liver and kidneys, the brain harbored seven to thirty times more, raising serious health concerns. This disparity suggests that the brain may be more susceptible to microplastic accumulation due to its lack of filtering systems akin to those in the liver and kidneys. Additionally, given that the brain is composed of about 60% fat, plastic particles may adhere more readily to its tissues. Despite the protective role of the blood-brain barrier, researchers were surprised to discover substantial amounts of microplastics within the brain.
Dr. Joseph Mercola, author of "Your Guide to Cellular Health," has long warned about the dangers of microplastics. He notes that these particles are not inert; they release endocrine-disrupting chemicals that can interfere with cellular repair mechanisms. Dr. Mercola advocates for prevention as the best strategy, advising individuals to limit their exposure by avoiding plastic water bottles, especially those exposed to heat, and being cautious about plastic containers coming into contact with food. He also suggests that maintaining a healthy body weight may help reduce the accumulation of fat-soluble plastics in the body. Additionally, engaging in activities that raise body temperature, such as using saunas, might aid in eliminating toxins, including microplastics.
