PHYSIOLOGICAL BASIS OF RATIONAL NUTRITION AND DAILY INTAKE OF NUTRIENTS

Nutrition is the process of intake, digestion, absorption and assimilation by the body of nutrients necessary to build and renew tissues, as well as to replenish the energy costs of the body. Food consists of complex compounds of plant or animal origin (proteins, fats and carbohydrates), from which, after their enzymatic hydrolysis, nutrients (nutrients) are extracted: amino acids, fatty acids, monosaccharides and glycerol, as well as vitamins and mineral salts. The first ancient theory of nutrition was created by Aristotle and Galen.
