Omega-3 May Reduce Risk of Heart Disease
by Wyn Snow, Managing Editor
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.
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.
