Yes, aluminum can be used to make cookware that is safe for cooking food. Aluminum cookware is widely used due to its lightweight, durability, and good heat conductivity. While there were concerns about aluminum's potential health effects, current research indicates that the amount of aluminum leached into food during normal cooking is minimal and not harmful to health. However, it's important to avoid using abrasive cleaners or utensils on aluminum cookware to prevent scratching, as this could increase the amount of aluminum that might be released into food.
