Are aluminum foils safe to use?

Aluminum foils are generally considered safe for use in cooking and food storage when used properly. They are non-toxic and do not leach harmful substances into food under normal conditions. However, it's important to avoid wrapping acidic foods or using foil with non-stick coatings at high temperatures, as this can cause the release of aluminum particles. Always use high-quality aluminum foil and follow the manufacturer's guidelines for safe usage.
