MICROPLASTICS: A POSSIBLE DRIVER OF BRAIN DISEASES It turns out the plastic problem might be a lot closer to home than we thought—maybe even inside your head. New research is pointing to a quietly unsettling link: those tiny plastic bits sneaking into your food, water, and even the dust in your house could be fueling brain inflammation and damage tied to Alzheimer’s and Parkinson’s. Most of us don’t realize it, but scientists say the average adult swallows around 250 grams of microplastics every year. That’s about enough to cover a dinner plate. And while our bodies do their best to clear out most of these invaders, some particles hang around—sometimes even winding up in our organs, including the brain. So what’s going on up there? According to a new review led by researchers from the University of Technology Sydney and Auburn University, microplastics may harm our brains in five different ways. They can set off immune cells, ramp up oxidative stress, bust open the blood-brain ba...
