Can aluminum foil be used for cooking?

Yes, aluminum foil can be used for cooking. It's versatile for wrapping foods, covering dishes to retain moisture, or lining baking sheets to prevent sticking. However, it's important to avoid using it with acidic or high-sodium foods, as these can cause the foil to break down and potentially release aluminum into the food. Additionally, do not use aluminum foil on high heat or in broilers, as it can melt and produce toxic fumes. Always use heavy-duty aluminum foil for cooking to ensure it can withstand the heat and conditions.
