  5. Minerals: They are essential for the proper functioning of the body’s metabolism. They are found in foods like meats, dairy products, and leafy green vegetables. Different minerals have different functions, such as helping the body form strong bones, carrying oxygen in the blood, and regulating the body’s fluid balance.
