[Urgent problems of rational nutrition for the immigrant population in Arctic regions and for the natives of the North].

Metabolic changes in newcomers to the Asiatic North have been revealed during their adaptation to a complex of the climatic and geographic factors of high latitudes. The changes were marked by making the most of lipids and less utilization of carbohydrates in energy supply to the adaptation processes. An important role of proteins in energy supply is discussed with emphasis on the changes in vitamin metabolism. The specificity of metabolic changes during adaptation is not taken into account in the nutrition program of the newcomers. This leads to the development of disadaptation shifts in the body. An important role of nutrition in adaptation of both the newcomers and aborigines of Siberia and North is suggested. The many-century experience gained in the nutrition of aborigines should be regarded in the newcomers' nutrition programs that are recommended to be based on protein-lipid diets.
