1 aluminum has been proved to be a major factor in Altzimers (no I do not sell cookware) 2 Teflon is so bad that it is being banned from cookware (where do you think the Teflon goes that comes off the pan) 3 If you guys do research you will find out why some beer companies are coating the insides of the cans.I told my husband about Keystone beer having this can but he will not drink it so i buy him miller in bottles.This will be a law in the near future 2010 that all aluminum cans be coated on the inside.
