78 views
Aluminum foil itself does not become toxic at any specific temperature. However, when used for cooking at high temperatures or with acidic foods, there is a potential for aluminum to leach into food. The World Health Organization considers safe intake levels of aluminum to be 40 mg per kg of body weight per week. To minimize risks, avoid cooking at very high temperatures or wrapping acidic foods like tomatoes and lemons in aluminum foil.
