How do you prevent aluminum from leaching into food when using aluminum foil facing?

To prevent aluminum from leaching into food when using aluminum foil facing, avoid direct contact between the foil and acidic or salty foods, as these can cause the aluminum to leach. Do not use aluminum foil at high temperatures, as it can degrade and release aluminum particles. Opt for aluminum-free alternatives like parchment paper or silicone baking mats for lining pans or wrapping foods. When using aluminum foil, ensure it's the heavy-duty type, which is less likely to break down and release aluminum. Always wash hands and utensils that have come into contact with aluminum foil to minimize ingestion of any residual aluminum.
