Jane, what is BPA, please?

please?BPA is a chemical that's been used to make plastic since the 1950s, but it turned out in the early 1990s that this chemical leaches out of plastics, and that BPA is a so-called endocrine-disrupting chemical, so it interferes with the hormone system, and it mimics the female hormone estrogen.

And that's [laughs] not something you want to have in food.

And it's recently been banned in the European Union, and the UK is following suit on that.

But it's still being found in food.

It's still been found to migrate, especially out of recycled plastics, for example.

And some containers say BPA free, but because BPA has such great functionality, the industry has replaced it with chemicals that are very similar in their structure to BPA.

Jane, are you worried about microplastics?
