According to the FDA and a study from the University of Clemson, aluminum from pots can leech into food. It depends on what and if the pot was coated with another material and the type of food. Certain acidic foods can react with the pot and cause more leeching. Scratches on the surface of the pot can also increase the leeching. Aluminum is a soft metal--that is why it can be made into foil.
