There may be a plastic spoon’s worth of microplastics in your brain. And if you have dementia? Research suggests you might have even more.

So how are these tiny plastic particles ending up inside us—and what are they doing to our health?

Dr. Hana Kahleova joins Chuck Carroll to break down the latest science on microplastics: where they come from, how they’re infiltrating everything from food to arteries, and what you can do to protect yourself.

In this episode, you’ll learn:

- What microplastics are and why they’re everywhere

- How microplastics get into the human body

- The surprising link between microplastics and heart disease

- Why seafood is one of the biggest sources of exposure

- How to spot avoid foods containing microplastics

- Why plastic containers and coffee cups are riskier than you think

- The powerful role plants play in helping your body eliminate plastic
