According to a medical expert, exposure to this metal might cause mental decline and loss of memory, bodily control, coordination, and balance. Moreover, when using aluminum foil for cooking, the bones are negatively affected as metal gathers in them and causes loss of calcium. As you probably already know, calcium is pivotal for proper bone health.
To make matters worse, cooking with aluminum foil was found to cause pulmonary fibrosis and other respiratory issues. When this foil is exposed to high temperatures through grilling or baking, the small bits of metal penetrate the food. Even if they’re not released, additional spices or lemon juice may lead to chemical leaching of aluminum.
A chemical engineering researcher at the American University of Sharjah, Essam Zubaidy,did a study in which he examined the effects of aluminum on cooking and found that a meal cooked in aluminum foil might have up to 400 mg of aluminum. He explained that the higher the temperature, the more the leaching. He also added that aluminum isn’t a safe option for cooking and he recommends avoiding it when cooking with tomatoes, citrus juices, or spices.
All in all, this foil can have detrimental effects on the brain, bones, and lungs. Therefore, avoid cooking with it as much as possible
