Given our exposure to microplastics, one Spanish-speaking listener asked us, Which basically means, how does consuming microplastics affect cardiovascular health? A question to which we'd like to add, how do microplastics impact health more broadly? Here's Heather Leslie again.

Microplastics are a large group of contaminants and they carry many different chemicals.

Which chemical cocktails are present in these particles that we're consuming will determine their toxic effects.

We don't have the weight of evidence yet to determine that such and such.

Microplastics exposure will result in this sort of health outcome, but we do see on a cellular level that cells don't like microplastics that much.

And they are an inflammatory type of contaminant.

And the chemical sauce that's leaching out of microplastics has, depending on the nature of the sauce and the ingredients in there, they can have hormone or endocrine disrupting effects.

How can we reduce our microplastics exposure? Let's listen to Heather Leslie's answer.
