Is Aluminum Foil Toxic When Heated?
There is no significant harm in using aluminum foil to wrap food items and heating them in the oven. However, if the foil is overheated or comes in contact with acidic or spicy foods, it can release aluminum ions that may leach into the food and cause health problems such as respiratory issues, kidney problems, and Alzheimer’s disease. Hence, it is recommended to avoid using aluminum foils for cooking purposes.
