What are the health effects of using aluminum foil facing to cook food?

Cooking with aluminum foil can potentially lead to the leaching of aluminum into the food, which may have health implications. While the body naturally eliminates small amounts of aluminum, excessive intake can be harmful. Aluminum has been linked to neurological disorders, including Alzheimer's disease, although the connection is not definitively proven. It's also important to note that the amount of aluminum that leaches into food during cooking is generally considered to be low. However, for those concerned about aluminum exposure, it's advisable to minimize the use of aluminum foil in cooking, especially for acidic foods which can increase the rate of aluminum leaching.
