Minerals are inorganic substances that are essential for various bodily functions, including bone structure, fluid balance, and nerve transmission. Unlike macronutrients such as carbohydrates, fats, and proteins, minerals do not contain any calories. Consequently, they provide no energy in the form of calories when consumed. Their roles in the body are crucial, but they do not contribute to the caloric value of the diet. This underscores the importance of minerals in nutrition while highlighting their unique characteristic of having a caloric value of zero.
