The answer is normal functioning of only a few organs (it should be all the organism).

The food is of animal, vegetable and mineral origins (water, salt).

- the renewal and manufacture of cell structures and therefore of the body. These are the building foods (growth and maintenance of the body).

- the energy allowing the functioning of the organism. To move, one needs energy and to have energy, one must eat energetic foods.

- Protection (mineral salts such as calcium, vitamins that promote cellular reactions).

Their contributions are complementary and contribute to the balance of the diet.
