March 31st could mark the end of the BPA era—when it comes to your food products, at least. By that date, the F.D.A. will reveal if they’ll ban the toxic chemical bisphenol A (BPA) from food packaging. This ruling would mean that BPA would no longer linger in infant food and formula, canned foods and drinks, or reusable food containers.BPA is a “fake” estrogen found in plastic linings and recycled products, which interrupts the natural functioning of your hormones. In animals, this brings on early puberty in children, and threatens fertility later in life. Beyond that, it can increase risk for cancers of the reproductive organs, and disorders of the heart and brain. Human data is only associated with those, but that is enough for us to avoid it, if at all possible.COLUMN: The Unfriendly, Everyday ChemicalAnd you much more likely than not have BPA in your system right this very moment!We’ve talked about the threats of BPA in previous columns.
