Is BPA found in all canned foods or just some of them?
One way to keep this from bothering you is to use only fresh, dried or frozen products. (This also removes a lot of sodium from your diet. First thing I learned after having heart problems)
It's in a lot of canned foods and the list of ones that don't have it isn't very big. There is a good list on this site.
