Are there any types of food that shouldn't be cooked in aluminum foil facing?

There are certain types of food that should not be cooked with aluminum foil facing. Acidic foods, such as tomatoes and citrus fruits, can react with the aluminum and potentially release harmful compounds. Foods high in salt or spices can also cause a reaction with the aluminum, leading to the leaching of aluminum into the food. Additionally, cooking acidic foods at high temperatures can increase the risk of aluminum contamination. It's best to avoid wrapping these types of foods in aluminum foil when cooking, or to use the dull side of the foil facing away from the food.
