It was in the late 1970’s when the nearly nonexistent incidence of heart disease was studied among the Greenland Eskimos, despite their very high fat diet. The answer to the puzzle lay in their universally large consumption of cold water fish. The reason oils from cold water fish are so beneficial is because they contain substanial amounts of Omega-3 fatty acids; namely eicosahexaenoic acid (epa) and docosahexaenoic acid (dha). EPA and DHA keep deposits of saturated fatty acids and cholesterol from gluing up our arteries. They also keep platelets from getting sticky and lower LDL cholesterol (bad cholesterol) while increasing HDL cholesterol (good cholesterol). Fish oil also makes a useful, completely natural adjunct to the treatment of arthritis. A group of eicosanoids called leukotrienes have been idetified as mediators of inflamation and the pain which accompanies this affliction. By supplementing the diet with Omega-3 rich fish oil, formation of these leukotrienes is remarkably suppressed.
