This freaks me out cause I give my kids canned soup all the time:
Maybe switch to making your own (where you have control over salt and fat) or to the packaged Knorr varieties?
a friend posted something similar in FB, it said all canned tomatoes, not just soup.
The only canned foods we eat are tomatoes - there are other options out there I've been researching.....there are some in tetra packs - Pomi out of Italy and Eden Foods has some in glass. Eden Foods also doesn't line their beans etc with BPA.....we've switched to dry beans though to avoid it all together
