Can aluminum foil be used for storing food?

Yes, aluminum foil can be used for storing food, particularly for wrapping and protecting it from air and moisture. It's often used to cover dishes for reheating in the oven or microwave, or to wrap food for freezing. However, it's not recommended for cooking acidic foods as they can react with the foil. Always ensure the foil does not touch any heating element directly to avoid fire hazards.
