Bisphenol A (BPA) has been in the news again recently. There are also pthalates in PVC and many soft plastics and ammonium perfluorooctanoate from teflon. In our house, we stopped buying polycarbonate bottles years ago (before we moved to California) and use BPA free bottles for our kids. With the latest news cycle, though we realized that most canned foods are also lined with BPA containing materials.
It's a scary world out there right now. The biggest thing we can see to do is to limit the amount of prepared food we eat and remove the obvious toxins from our immediate environment. We've already dropped the hard plastic Nalgene and Avent bottles. Although both are starting to make non-BPA versions, I still feel more comfortable going back to the old polypropylene ones. They're not as pretty but pretty well tested. Most research labs store at least some things in polypro bottles. Someone would have noticed something by now. That's how BPA was recognized as a problem.
We are also going to try to limit canned food until we figure out how to tell which don't use BPA. Apparently it's banned in Canada. Maybe we'll make a monthly trip to Montreal to stock up. That gets at one of the problems we're facing. Last winter we decided to make do with canned veggies instead of fresh imported ones in an attempt to reduce our food-miles. Maybe we'll have to start canning our own stuff in glass jars with what's left of our free time.
