A recent research study performed on the Eskimos has established the links between various individual fatty acids and components of the metabolic syndrome, such as dyslipidemia and glucose control.

Eskimos

Researchers across the world have been conducting several studies on the fatty acid related impacts on the cardio-vascular system specifically in extremely cold environmental conditions The Eskimo population therefore has long attracted the attention of researchers because of its low rates of the metabolic syndrome and cardiovascular disease, owing to consumption of high amounts of omega-3 fatty acids.

The current study, known as the “Genetics of Coronary Artery Disease in Alaska Natives” (GOCADAN), sought to take these research findings a step ahead by attributing specific fatty acids to specific changes in features of the metabolic syndrome.

Sven Ebbesson and colleague researchers at the “Norton Sound Health Corp, Fairbanks, Alaska, USA” conducted this study in controlled conditions. The study involved 691 Inupiat Eskimos from the Northwestern Alaskan area, aged 34-75 years. Findings of this research study and the results analysis have been published in “The Journal of the Cardio metabolic Syndrome” recently.

Data collected from physical examination, blood testing, and dietary questionnaires under this study showed that high consumption of long-chain omega-3 fatty acids, averaging 6 g a day and coming mainly from fish and sea mammals, significantly reduced blood pressure and serum triglyceride levels, and significantly improved glucose control and high-density lipoprotein cholesterol concentrations.

On the other hand, the increasing consumption of saturated fat was linked to rising triglyceride levels and blood pressure, and high intake of trans-fatty acids was linked with significant increases in blood pressure. Interestingly, ?-linolenic acid consumption had no effect on any component of the metabolic syndrome tested.

Based on these research study findings, Sven Ebbesson at the ‘Norton Sound Health Corp, Fairbanks, Alaska, USA’ and colleagues suggest that the well-established link between increased consumption of fish oils and reduced risk of cardiovascular disease is at least partly due to the attenuation of components of the metabolic syndrome.

Sven Ebbesson further added in the conclusive remarks of the published study report, “Our finding that ?-linolenic acid had little or no effect on any metabolic syndrome component supports the finding that a-linolenic acid intake has no effect on risk of incident coronary artery disease through these mechanisms”.
