Don't: Overstock Canned Foods
Unfortunately, plastics aren't the only packaging that leach chemicals into foods. The lining of cans also contains the suspect chemicals bisphenol-A and phthalates, both of which can mimic human hormones. A recent analysis found that families can reduce their exposure to the two chemicals by more than 50% simply by steering clear of canned foods, like soups, tuna and beans. Canned foods are an important part of emergency preparedness, though, so you'll probably want to keep some on hand just in case. Eden Organic is one brand that uses BPA-free cans.
