A Word on Canned Foods:
The U.S. Food and Drug Administration allows BPA to be used in food cans. According to the Environmental Working Group, levels of BPA vary greatly, even in different cans of the same food, making it difficult to label any canned foods as better or worse than others. However, a few canned foods sometimes measure high in BPA: beans, green beans, green peas, and chili. Others, mainly fruits and beverages, tend to have low concentrations of BPA.
