Influence of Variable Quantities of Dietary Energy and Protein on Nitrogen Retention in Adolescent Girls

The ability of any protein to satisfy the physiological needs and the efficiency with which the needs can be met depends upon the amino acid pattern of the protein and the efficiency of its utilisation, which in turn, is dependent upon the level at which the protein is fed and the adequacy of the caloric supply. Numerous other factors also influence nitrogen retention, such as, the ratio of dietary protein to total calories, muscular activity, cooking practices, frequency of meals and the quantity of food needed to give satiety value. The experiment was devoted to study the influence of variable quantities of dietary energy and protein on nitrogen retention in adolescent girls.
