Features essential omega 3 polyunsaturated fatty acids content and glucose level in adult residents of the Arctic region

The study aims to determine the level and identify the nature of the relationship between the content of ω-3 polyunsaturated fatty acids (PUFA) and the glucose level in practically healthy people of mature age in the Arctic region. Materials and methods: The study covered 1,689 individuals, of whom 939 are residents of the Arctic Region and 750 of the sub-Arctic Region. The content of essential omega-3 PUFA was determined by gas-liquid chromatography in serum, while the level of glucose was determined by spectrophotometry. Results: Regardless of region of residence, the age-related increase in glucose levels, their values in the Arctic region being abnormally high, are associated with an increase in the content of essential ω-3 PUFAs, which is confirmed by the majority of direct correlations between glucose and omega-3 PUFAs C18: 3n3, C205n3, C226n3), compared with sub-Arctic region (C226n3).
