Background . The rational nutrition of the child population is given great medical importance as a factor in preserving the health and development of the child. A complete and balanced diet in terms of the content of basic nutrients ensures the normal growth and development of the child’s body. The aim . To analyze of the actual nutrition of adolescents living in rural areas of the Irkutsk region. Materials and methods . The study involved 69 rural adolescents aged 11–17 years (34 boys, 35 girls). The actual nutrition was studied by the method of 24-hour nutrition reproduction. The energy value of the diet was determined, the nature of the provision of the diet with basic macro- and microelements was studied. The obtained values were compared with the norms of  physiological needs for energy and nutrients in 2008 and 2021. Results . The analysis of actual nutrition revealed deviations from the principles of  healthy nutrition: insufficient energy value of the diet, deficiency of proteins and  fats. The diet of  adolescents was characterized by an insufficient content of the main groups of macro- and micronutrients – vitamins A, C and D, essential trace elements, and a deficiency of dietary fiber. The diet of adolescents was characterized by increased sodium intake. The calculated ratio of proteins, fats, carbohydrates indicated a carbohydrate type of diet. Conclusion . Despite the great attention to the problem of balanced nutrition of adolescents, the question of the impact of nutrition on the health of a teenager, considering the regional factor, remains open. Recommendations for the development of a regional program for the organization of proper nutrition for school-age children are of great practical importance.
