The method of daily ration reproduction was used to study the actual nutrition of 25% of male subsampling comprising 674 subjects, during the epidemiological investigation of unorganized male population in a region of Ufa. The results of the study have shown that the caloric value of their nutrition does not exceed the established standards and is diminished with age. Protein consumption meets the physiological requirements, animal proteins prevail in their structure. Carbohydrate consumption is low, mainly at the expense of starch, while the share of sugar is high. Fat consumption exceeds the values recommended, mainly at the expense of saturated fatty acids. Cholesterol consumption is excessive. The established nutrition imbalance of the main food substances has evidenced the atherogenic character of the population nutrition, prevalence of animal food products in its structure, that should be taken into consideration when measures for the prevention of coronary heart disease are elaborated.
