Omega-3 May Reduce Risk of Heart Disease
28 October 2002
by Wyn Snow, Managing Editor

Omega-3 fatty acids can reduce high blood pressure and thereby reduce the risk of heart disease, according to a study published in the American Journal of Clinical Nutrition. The study examined the effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on the elasticity of large arteries. Increased stiffness in these arteries can lead to hypertension and increased pulse pressure (the difference between diastolic and systolic pressure). These factors are believed to contribute to heightened risk of heart disease.

Normally found in fish, omega-3 fatty acids are also available in supplements. In the 7-week study, 38 middle-aged men and women with high levels of blood cholesterol were given an EPA supplement, a DHA supplement, or a placebo. While the placebo group showed no changes, improvements in systemic arterial compliance and triacylglycerol concentrations were seen in both supplement groups.
