Is BPA in You?

You won't see it on any ingredients list, but you probably ingested bisphenol A today. Used to make the polycarbonate plastics found in many consumer goods - reusable water containers, baby bottles, the inside coating of tin cans - BPA can leach into foods and liquids when the plastic ages or gets heated. While the FDA recognizes the chemical as afe, some studies show low levels can disrupt hormone and immune system function, and cause insulin resistance and birth defects. It's another reason to keep a stainless-steel canteen close by.
