Since then we’ve learned to limit our exposure to this endocrine disrupter by switching from polycarbonate to stainless-steel water bottles for grownups and from hard to soft plastic milk bottles for babies, and eleven U.S. states and even China have joined Europe and Canada in banning BPA from baby bottles. Those of us beyond babyhood, however, tend to take in BPA mainly through canned food.

Scientists and governments disagree about the magnitude of this problem, and even whether it’s…
