[Use of new products with increased biologic value for nourishment of school aged children].

Rations in which new protein-rich, fat and cultured milk products are included have been worked out. These products made it possible to enrich the rations with a full-value protein, essential fatty acids, mineral substances and vitamins. Under observation were kept 60 schoolchildren, students of specialized and boarding schools aged from 13 to 16 years. The studies covered their health status, the degree of their fatiguability in the course of learning and the state of some factors characterizing metabolic processes proceeding in their organism. The enrichment of the adolescents' ration with products of an elevated biological value had a beneficial influence on the metabolism, physical development and performance capacity. All this justifies recommending wide use of new protein-rich fat and cultivated milk products in the dietary at boarding schools, account being taken of greater academic and teaching requirements.
