While aluminum foil is widely used in cooking and food storage, there is limited evidence to suggest significant health risks. Some studies have linked aluminum exposure to neurological conditions like Alzheimer's, but the connection is not conclusive. The body does not absorb significant amounts of aluminum from foil, especially when used properly. However, it's important to avoid wrapping acidic or highly acidic foods in aluminum foil, as this could potentially lead to increased aluminum leaching. Overall, using aluminum foil in moderation and following proper food handling practices can minimize any potential risks.
