Currently, there is an objective need to create fortified food products that allow not only to provide the body with energy, but also to replenish the deficiency of essential nutrients. A generalization of the information published by Rospotrebnadzor and the Institute of Nutrition of the Russian Academy of Medical Sciences indicates a deficiency in the diet of Russians of vitamins C, group B and β-carotene and minerals, including calcium and iron, regardless of the season of the year. The identified deviations lead to a violation of the immune status, a decrease in the body’s resistance to infections, and other unfavorable environmental factors, leading to an increase in the level of morbidity and a decrease in working capacity. The main unfavorable climatic factor that the population of the Far Eastern region has to face is low freezing temperatures. Adaptation to cold exposure is a complex process that requires a long period and may be accompanied by functional disorders and morphological changes in body tissues. In connection with the above, the problem of increasing the adaptive capabilities of a person to unfavorable environmental factors by means of correcting daily nutrition, providing the body with essential macro- and micronutrients, which is important in the prevention of possible diseases, is of particular importance. This study is aimed at assessing the effect of Schisandrachinensis extract on the adaptive capacity of rats in conditions of chronic and general cold. It was found that the extracts obtained from the fruits of Schisandra chinensis are characterized by a high content of biologically active substances. In experiments with determining the duration of running on the treadmill, a distinct act-protective effect was observed with the introduction of Schisandra chinensis extracts at a dose of 150 mg/day, against the background of reduced resistance to physical activity due to cold exposure. It was found that exposure to cold significantly reduced the swimming resistance of rats on all days of the study. The introduction of Schisandra chinensis extract into the diet led to an increase in resistance to fatigue and an increase in the duration of swimming on all days of the experiment. Conclusions: in this experimental model, a gradually increasing effect of increasing the physical performance of rats was demonstrated with prolonged (28 days) intake of the developed drinks, which coincides with the literature data on a number of other adaptogens and indicates the presence of cumulative properties of biologically active substances of Schisandra extract.

The population of the Far Eastern region is under stress due to daily exposure to harmful and carcinogenic substances in the air, with average annual levels exceeding health standards. The purpose of this study is to assess the medical and environmental situation in the Far Eastern region and to identify relationships between environmental factors and the incidence in the population. For four years, studies have been conducted to assess the impact of environmental pollution on public health using basic demographic and morbidity indicators for the emissions of harmful substances, according to the data from State reports “On the sanitary-epidemiological situation in the Russian Federation” and statistical data from the Federal Statistics Service of the Russian Federation. In the course of this research, it was found that the increase in the incidence of malignant neoplasms was promoted by an increase in the amount of air-polluting emissions and an increase in the proportion of people employed in heavy work under conditions that do not meet health requirements. Using the regression equation, the impact of the amount of wastewater discharges and the amount of pollutants emitted into the atmosphere demonstrated an increase in respiratory diseases. As a preventive measure against negative environmental factors, the mandatory use of local adaptogens in everyday food products has been proposed.
