BPA is a hormone disruptor, of which infants and children are particularly susceptible. BPA is found in canned foods and polycarbonate bottles. Look for the recycling numbers 3 and 7 for its presence. BPA leaching is greatly sped up with heat, so don’t heat food in the microwave in plastic containers or on plastic plates.
The World Health Organization (WHO) just came out with a report calling hormone disruptors a “global threat.” The co-author of the report, Thomas Zoeller, a professor at the University of Massachusetts, Amherst, tells us, “Frankly, for BPA, the science is done. Flame retardants, phthalates . . . the science is done . . . We have more than enough information on these chemicals to make the reasonable decision to ban, or at least take steps to limit exposure.”
