Researchers have discovered microplastics in various parts of the human body, including the brain, heart, lungs, and kidneys. The tiny fragments are released from larger plastic items when they break down or shed during use. While studies suggest that microplastics may pose a health threat, it is not yet clear if they contribute to conditions like dementia or increase the risk of heart attacks and strokes.
A recent study found jagged microplastics in carotid artery plaques, which increased the risk of heart attack, stroke, or death. Another review of evidence suggested that exposure to microplastics may harm human digestive and respiratory health, including a potential link to colon and lung cancer.
Experts agree that microplastics could harm human health, particularly for older adults whose bodies are less able to repair damage from plastics. However, more research is needed to confirm the risks.
To reduce exposure to microplastics, researchers recommend cutting back on single-use plastics and choosing alternatives whenever possible. This can include switching to reusable plastic wrap, bags, cutlery, and food containers.
