Microplastics in human brains could impact mental health

Microplastics, tiny plastic particles pervasive in the environment, have been found to accumulate in the human brain, raising concerns about potential mental health effects, Earth.com reported.

Researchers, including Dr. Nicholas Fabiano from the University of Ottawa, warn that these particles enter the body through diet and air inhalation and may disrupt brain function. Ultra-processed foods are suspected to increase plastic intake due to industrial processing methods introducing synthetic elements.

Studies reveal microplastics can persist in the body, possibly causing inflammation and oxidative stress in sensitive tissues like the brain. Early research explores blood-filtering techniques to remove these particles, though results remain preliminary. Experts urge reducing exposure by avoiding plastic packaging and choosing fresher foods.

While the link between microplastics and cognitive or emotional health is still under investigation, calls for transparent food labeling and stricter packaging regulations are growing. Collaborative scientific efforts aim to clarify exposure risks and health impacts, emphasizing lifestyle adjustments and policy changes to minimize microplastic contamination. The study is published in Brain Medicine.
