Many canned foods and obviously found in cans. Most cans are lined with a chemical called bisphenol-A or BPA. Study about 2 years ago showed that BPA’s affect the way genes worked inside rats’ brains. The FDA seems to agree this is a problem and is supporting efforts to reduce, replace or eliminate the amounts found in canned foods. The high acidity leaves tomatoes more dangerous because they can leech the BPA more readily from the can lining.
Perhaps the moral of our story is if you dont know what is in your food and it isnt non-processed then do your research on it and think twice for a healthy lifestyle.
