Microplastics drastically increase heart disease risk in male mice by accelerating artery plaque buildup, but not in females, researchers say.
A new study links microplastic exposure to a significantly increased risk of heart disease by accelerating atherosclerosis in male mice, with up to 624% more arterial plaque, though no similar effect was seen in female mice.
Researchers found no changes in weight or cholesterol, suggesting microplastics may directly damage arteries.
The particles, found in food, water, air, and human tissues, are nearly impossible to avoid.
Experts urge reducing exposure through lifestyle changes and call for more research to determine if similar effects occur in humans.
