Many people are wondering whether aluminum foil containers are safe or not. Zhengzhou Eming Aluminum Industry will show you something.
The amount of aluminum that leaches into food, however, is minimal. In lab tests, tomato sauce that we cooked in an aluminum pot for two hours and then stored in the same pot overnight was found to contain only .0024 milligrams of aluminum per cup. (A single antacid tablet may contain more than 200 milligrams of aluminum.) Our science editor reports that the consensus in the medical community is that using aluminum cookware poses no health threat.
In short, while untreated aluminum is not unsafe, it should not be used with acidic foods, which may ruin both the food and the cookware. Also note that aluminum cookware that has been anodized (hardened through a process that renders it nonreactive) or clad in a nonreactive material, such as stainless steel or a nonstick coating, does not leach into or react with foods.
