I've been worrying about BPA a bit -- I never liked the taste of water in nalgene bottles and switched to aluminum awhile ago, but was not sure what exact types of products contain this harmful chemical. So in case you've been worried too,
here is a link to a New York Times article that I thought was helpful on the subject.
Main take-away for me:
1) BPA lines most canned goods, so stop cooking with canned beans (Soaking dried beans takes longer but cheaper so that's ok) or other canned fruits/veggies
2) The #7 inside that recycle tryiangle on the bottom of plastic packaging MAY indicate BPA if the plastic is clear and hard (but it may be a harmless plastic b/c that's a catch-all)
Better for the environment to avoid all this packaging anyway. Happy Earth Day BTW!
