The article shows the value of macronutrients, which, along with other food ingredients, form various structures of the body. The data on the content of macronutrients in the diets of the population of different age groups for the period 2004-2020, living in the settlements of the Kyiv region and exposed to the impact of the consequences of the Chernobyl accident, are presented. Aim of the Research. The aim of the study was to summarize data on the content of minerals in the diet of the population living under the influence of radiation exposure. The main attention is paid to organic elements (phosphorus, potassium, sulphur, chlorine, calcium, magnesium and iron), which form almost 98% of the chemical composition of the cell. Their total content is up to 1.9 % of the mass of the human body. Material and Methods. To achieve this goal, a set of methods was used, in particular: bibliographic — a theoretical analysis was carried out and the data from scientific literature was generalized; questionnairesurvey — the actual content of macronutrients in the diets of different age groups and mathematics were analyzed. Statistical data processing was carried out using modern methods of medical statistics. Results and Discussion. Regular provision of the body with all the necessary nutrients is of great importance for maintaining health, performance and active longevity of a person. Our longterm research conducted among the population of ecologically dangerous territories of Ukraine found that the content of macronutrients in the diets of adults, children and pregnant women did not meet physiological needs. Conclusion. The content of macronutrients in the diet of the surveyed population was unbalanced. Diets deficient in the content of calcium (Ca) and magnesium (Mg), the optimal ratio between macronutrients is disturbed, which can be the cause of premorbid conditions and be the reason for the formation of alimentary and alimentary-dependent diseases. The article is relevant for family doctors, hygienists, nutritionists, nutritionists and individuals interested in nutritional problems.
