Recent research from the University of New Mexico suggests that most humans have a teaspoon-sized amount of microplastics in their brains, raising concerns about potential health risks. Pierre Herckes, Professor at ASU’s School of Molecular Sciences, joined Arizona Horizon to discuss the findings. He explained that microplastics, which enter the body through food and liquids, have been detected in vital organs such as the liver, heart, and brain. While the long-term effects remain uncertain, scientists worry about possible links to heart disease, strokes, and neurodegenerative conditions like dementia.

Professor Herckes emphasized that the presence of microplastics in the human body is rapidly increasing, with levels 50% higher in 2024 compared to 2016. He noted that plastics contain various additives, including BPA and other chemicals, which could pose additional risks. To minimize exposure, he advised avoiding plastic bottles, not microwaving food in plastic containers, and using wooden cutting boards instead of plastic ones.
