Q: I read not so long ago that BPA may cause childhood obesity. Can you tell me if that is true and what should I do to limit my child’s exposure to BPA?
A: BPA is the abbreviation for Bisphenol A, a breakdown product of coatings that prevent metal corrosion in food and beverage containers. It is used to manufacture polycarbonate resins. For a number of years, experts have become increasingly concerned that it may be unhealthy – especially to the very young. BPA was banned from baby bottles and sippy cups a few years ago.
