How do I avoid getting metal flakes from aluminum foil facing into my food when using it?

To avoid metal flakes from aluminum foil getting into your food, first ensure you're using heavy-duty aluminum foil, which is less likely to tear. Avoid using foil for acidic or highly acidic foods as they can cause the foil to break down. When handling foil, use utensils instead of your hands to prevent oils and salts from your skin causing the foil to flake. Also, do not use foil in broiling or high-heat situations as it can cause the foil to break down and release flakes. Finally, consider using parchment paper or silicone baking mats as alternatives to aluminum foil for certain recipes.
