Long-term treatment of N-3 PUFAS on plasma lipoprotein levels and fatty acid composition of total serum and erythrocyte lipids in hypertriglyceridemic patients.

The low incidence of coronary heart disease in Greenland Eskimos and Japanese fishermen who have high consumption of fish and seafood has called the attention in the role of eicosapentaenoic (EPA = 20:5n-3) and docosahexaenoic (DHA = 22: 6n-3) acids, the major n-3 polyunsaturated fatty acids (PUFAs) in fish oils, in reducing cardiovascular risk. N-3 PUFAs may reduce serum lipids by promoting fatty acid oxidation and decrease VLDL producing from the liver, depress tissue arachidonate synthesis and alter the composition and tissue PUFAs. Plasma lipoprotein and fatty acid composition of total serum and erythrocyte lipids in 9 hypertriglyceridemic patients consisting of 4 males and 5 females aged 39-72 yr who attended the Nutrition Clinic, Ramathibodi Hospital were investigated.
