Features of the chemical composition of the diet and nutritional status of indigenous and newcomers in the Russian Arctic

The study of actual nutrition and nutritional status was conducted in 180 residents of the settlements of Tazovsky and Gyda of the Yamal-Nenets Autonomous District. In comparison with the out-of-town population, Arctic indigenous people reliably consume bakery products, meat products (due to venison), fish and fish products, and less - dairy products, vegetables and mushrooms, fruits, berries, dried fruit, vegetable, fruit and fruit juices. When analyzing the chemical composition of the diet, in comparison with the indices of the newborn population, the caloric content of the ration was significantly higher because of its higher protein content (18% of calories). The fat content in the diet of the indigenous population was almost close to the recommended values (30% by caloric content), while in the alien population it exceeded them (33%). The indigenous population, in comparison with the out-of-home population, had a lower content of total and animal fat in the diet, mono- and disaccharides against a background of lower BMI (27.2 kg / m² and 28.8 kg / m², respectively) and fat mass. Body factors also were affected by genetic factors. The indigenous population consumed less Vitamin C (2 times) compared to the alien, which was due to the significantly lower content of vegetables, fruits, berries and fruit juices in their diet, and Ca at an unfavorable ratio of Ca: P (1: 2.5) On the background of insufficient intake of dairy products, and more - sodium due to canned (smoked, dried and salted) fish.
