what are the six essential nutrients?
There are, however, some 45 or so nutrients that the human body is incapable of manufacturing. These nutritional elements are called essential because it is essential for humans to incorporate them into their diets. The essential nutrients can be divided into six general categories: water, proteins, carbohydrates, fats, vitamins, and minerals. Strictly speaking, fiber is not an essential nutrient, but it is also extremely important in prevention of certain diseases.
