There's a problem with toxic chemicals in our canned food. The problem is bisphenol-A (BPA), a common additive in plastic products, including the plastic inner linings of food cans. BPA is an endocrine disruptor that has been linked to an array of health problems. The Breast Cancer Fund have published the results of a new study that found BPA lurking in a number of the staples of a Thanksgiving table, having leached from the can-linings into the food itself.

They tested canned foods like turkey gravy, creamed corn, cranberry sauce, canned pumpkin, evaporated milk, green beans, and cream of mushroom soup. They found that single servings of nearly half of the tested products showed BPA levels linked to adverse health effects. The study also found high variability in BPA levels even among cans of the same product. Their conclusion: Until BPA is phased out entirely from can linings, consumers can never be sure if their canned food contains BPA or not. The solution: Make your own gravy, use fresh or frozen ingredients, and buy food packed in glass jars if you can.
