Cooking Foods in Their Own Can

EarthTalk:: "As for what metals may be leaching into your canned food, it depends. In the U.S., most food cans are made of steel while beverage cans are usually made out of aluminum. Chromium and nickel can find their way out of steel, but the amounts would be miniscule to nil. Slightly more troubling is the fact that aluminum—large amounts of which have been linked to nervous system disorders and other health problems—could in theory leach out of cans into their food or drink contents."
