Multiple micronutrient deficiency (simultaneous insufficient supply of the organism with several vitamins at once (vitamin D, B group), as well as calcium, magnesium, zinc and iodine, and not an isolated deficiency of any one micronutrient is characteristic of a significant part of the Russian population throughout the year, regardless of places of residence. The growing need of the organism at different periods of life (puberty, pregnancy, breastfeeding, aging), various diseases, drug therapy, the period of convalescence, stress, the use of various diets, enrichment of the diet with polyunsaturated fatty acids and dietary fiber, religious observance, adverse environmental factors further increase the risk of multiple micronutrient deficiencies. Micronutrients (vitamins and essential minerals) are closely interconnected into complex metabolic networks, which provide maintaining homeostasis and health. Deficiency of each of the essential micronutrients is a risk factor for the development of a particular disease, and simultaneous multiple micronutrient deficiency creates a “causality network” of not just one, but several diseases at once. Conversely, an adequate or optimal sufficiency of the body with all micronutrients, respectively, creates a “network of conditions ensuring the prevention of the disease”, due to the full implementation of all processes dependent on them in the body. This means that replenishing inadequate food intake of scarce micronutrients is an important way to maintain health and longevity. Given the variety of vitamin-mineral supplements, it is important to choose the right supplement. The maximum effectiveness to maintain the body’s vitamin and mineral status at the optimum level will be ensured by the intake of not individual micronutrients, but vitamin and mineral supplements containing a complete set of vitamins in doses close to the physiological needs of the body and basic minerals (calcium, magnesium, zinc and iodine), the deficit of which is characteristic for the Russian population.

Introduction. A healthy diet has a multi-component protective effect on the state of health, ensures the optimal functioning of all processes in the child's body, especially during a pandemic. Objective of the study: to study the actual nutrition of middle-level schoolchildren during the period of quarantine restrictive measures for COVID-19, studying remotely. Material and methods. A sample study was conducted to assess the actual nutrition of middle school students in grades 5–7 at the age of 12–13, living in different single-industry towns of the Kemerovo region, whose parents agreed. Actual food intake was studied by 24-hour nutrition reproduction (n = 40). The comparison of qualitative and quantitative characteristics of the composition of the food diet was carried out on the basis of the current norms of sanitary legislation and the newly issued methodological recommendations of the Federal State Budgetary Institution «Federal Research Center for Nutrition, Biotechnology and Food Safety». Results. In the nutrition of children there is a shortage of consumption of fish and seafood, eggs, milk and dairy products, vegetables, fruits, juices. In daily diets in excess bakery and pasta products, sausages and confectionery products, sugar. The energy value of the diets of school students exceeds the norms of physiological need recommended during the quarantine period. Nutrition is unbalanced in terms of the content of macronutrients: against the background of the sufficient contribution of proteins and carbohydrates to the total calorie content of the diet, an excess of fats and a lack of a quota of vegetable fats were revealed. The diet model of school students formed at home led to a shortage of intake with a diet of micronutrients: vitamins В1, В2, PP, A, as well as an imbalance in the consumption of phosphorus, calcium, magnesium and sodium. Conclusion. Studies have revealed that the diet of school students during their stay at home in quarantine does not meet the principles of a healthy diet, is unsustainable in terms of food set.
Introduction. The analysis of actual nutrition on weekdays of children attending preschool educational institutions of Mezhdurechensk, one of the monotowns of Kuzbass, is carried out.Material and methods. The actual food consumption in kindergarten was studied by the weight method (21240 individual servings), at home it was studied by the 24-hour nutritional method. 358 preschool children were examined.Results. An increased caloric diet due to excess fat content was established (37.3% higher than physiological consumption standards). A deficiency of 11.5% of the norm of dietary fiber was revealed. The average daily diets of preschoolers provided age-related needs for macronutrients (107-137%), vitamins (119-158%), and minerals (109-157%). However, during the stay of children in kindergarten, the caloric value of their diets did not cover the age-related physiological needs of the child’s body, which was established by the weight method. Diets were not balanced by micronutrient composition.Discussion. The reasons for the possible refusal of children to eat in kindergarten or the appearance of poor appetite in children were a violation of the daily routine: replacing outdoor walks with group exercises, individual lessons with a speech therapist; dinner transfer. The excess caloric value of daily diets is formed due to the contribution of home nutrition in the evening (an average of 45.0% of the physiological norm of a child with the necessary norm of 20-25%). In the structure of the food set, a deficit of more than 10% of rye bread, fish and seafood, the excess of legumes and cereals (by 28% of recommended consumption standards), pasta (by 83%), sausages (by 135%) and confectionery products (by 51%) were revealed.Conclusions. The findings suggest that the main eating disorders of preschoolers are formed in the family.
