There are two types of nutrients, simple or micronutrients (the body needs them in small doses) and macronutrients (they are required in large quantities).

Proteins, fats, carbohydrates, vitamins and minerals are the five groups in which the essential nutrients of any diet are classified. In total, these groups comprise between 45 and 50 substances that are considered essential for proper growth and maintenance of health.

The type of food that is most abundant in the world are carbohydrates, with fats being the easiest to accumulate. If our body depletes its reserves of fats and hydrates, it will directly use the dietary protein or glycogen stored in the muscles, breaking it down to form its own fuel.
