after i made my tortilla soup, i saw an article about issues with canned tomatoes. the reason i looked at this again was because i remember reading about this before.
problem with canned tomatoes: “The resin linings of tin cans contain bisphenol-A, a synthetic estrogen that has been linked to ailments ranging from reproductive problems to heart disease, diabetes, and obesity. Unfortunately, acidity (a prominent characteristic of tomatoes) causes BPA to leach into your food.”
it is not yet conclusive how big a problem the toxicity of canned tomatoes can cause in adults but it may be more of an issue with is if you are pregnant, nursing or have young children. but if you do have some, it is not a red flag. even with young kids, once a week should not be a problem, just probably not daily.
