Effects of fish-oil ingestion on cardiovascular risk factors in hyperlipidemic subjects in Israel: a randomized, double-blind crossover study.
1990
Effects ofa daily fish-oil supplement on serum lipids, apolipoproteins, and some platelet functions and he- morheologic variables were examined in 27 hyperlipidemic sub- jects in a randomized, controlled, double-blind, crossover fashion with an identically encapsulated vegetable oil serving as the con- trol treatment. Despite the habitual high linoleic acid intake of the study population, significant incorporation ofn-3 (�,-3) fatty acids into the serum, platelet, and erythrocyte lipids was observed after the fish-oil supplement. Ingestion of fish oil resulted in a 40% decrease in the triglyceride concentration, a 12% increase in HDL cholesterol, and a significant decrease in plasma vis- cosity, whereas the vegetable-oil placebo had no significant effect. We conclude that a moderate intake of fish oil (1 5 g/d) is a feasible treatment for hypertriglyceridemia even in patients with a background of high linoleic acid intake and that it may have a beneficial effect on several cardiovascular risk factors.
