Microplastics are promoting atherosclerosis, the buildup of plaque inside your arteries that leads to heart attacks and strokes. A new study details exactly how.
What the Study Found
A 2026 study on microplastics and atherosclerosis maps out the mechanisms by which microplastics drive arterial plaque formation. The particles cause endothelial damage, promote lipid accumulation in vessel walls, trigger inflammatory immune responses, and alter cholesterol metabolism.
Atherosclerosis is the leading cause of heart disease and stroke worldwide. If microplastics are accelerating it, the global plastic pollution crisis is directly connected to the global heart disease crisis.
What You Can Do
Reduce microplastic exposure at every opportunity. Filter water. Avoid plastic food containers. Use glass and stainless steel. Eat anti-inflammatory foods. Exercise regularly to support cardiovascular health.
