Pay attention to the food you eat, and cut out the crap, especially processed items. Lots of canned goods contain bisophenol a (bpa), which is used to line cans, including soda. The highest concentrations have been found in chicken soup, ravioli: and surprisingly: infant formula. Bpa is linked to certain types of cancer in lab animals. To avoid exposure, cut down or eliminate canned goods altogether, use powdered formula, and stay away from polycarbonate plastic food containers.
