Can microplastics raise heart health concerns?

What microplastics are
Microplastics and nanoplastics are tiny plastic pieces. People can take them in through food, drink, air, and dust.
The heart-health question is still new. Scientists are studying whether these particles affect blood vessels and inflammation.
What the research says
A 2026 review in Annual Review of Pharmacology and Toxicology explains possible mechanisms linking microplastics and cardiovascular health.
The review says microplastics and nanoplastics can disrupt biological processes such as autophagy, inflammation, oxidative stress, immune activation, and vascular dysfunction. It also says the link with cardiovascular disease remains unclear and needs stronger prospective studies.
What to do at home
Use measured caution. Reduce plastic contact where the swap is easy. Store food in glass, avoid heating food in plastic, and choose reusable kitchen materials that do not shed or break down quickly.
