Are microplastics and BPA driving blood vessel damage?
Yes. Peer-reviewed research confirms that microplastics in the bloodstream can cause cell blockages and lead to serious vascular conditions like atherosclerosis.
What's actually in it
Microplastics are tiny pieces of plastic that end up in your body through the food you eat and the air you breathe. When these particles enter your bloodstream, they don't just pass through. They can physically obstruct your cells, according to a 2025 study in Sci Adv.
These particles often carry other harmful substances. For example, a 2026 study in Environ Pollut found that polycyclic aromatic hydrocarbons (toxic chemicals often found in pollution) can bind to microplastics. This combination makes them more toxic and causes damage to your cells.
What the research says
The link between plastic particles and blood vessel health is clear. A 2026 study in Annu Rev Pharmacol Toxicol highlights the direct connection between microplastics and atherosclerosis, which is the hardening and narrowing of your arteries.
When these plastics reach your blood, they can cause cerebral thrombosis, which is a blood clot in the brain. A 2025 study in Sci Adv shows this happens because the particles physically block cells from moving correctly. This can even lead to changes in how your brain functions.
Other types of plastic, like PTFE (Teflon), are also linked to internal damage. A 2025 study in J Hazard Mater found that these microplastics cause oxidative stress and damage the mitochondria, which are the power plants of your cells. This research proves that these materials are not safe for your body.
