If you use hard plastics for just about anything, you've probably been exposed to the chemical BPA. It's in Tupperware, water coolers, some baby bottles. It can leach(ph) into foods. Almost all of us have some traceable amount of it in our bodies. And now the FDA is saying that it's dangerous, but not dangerous enough to ban it - dangerous enough to try to reduce our exposure to it. But how do you do that when it's just about everywhere? And if it's such a problem, why did the FDA wait so long to warn us about it?
