The analysis found that hypertensive study participants who received the Omega 3’s DHA and EPA had an average decrease in systolic pressure (the top number in the reading) of 4.51 mm Hg, while diastolic pressure fell an average of 3.05 mm Hg, compared to the placebo group. Small Decreases in Blood Pressure Could Save Thousands of Lives A simple blood test called OmegaCheck™ can measure the balance of fatty acids in a person’s diet. Research suggests that people with lower omega-6 to omega-3 ratios have a reduced risk for such conditions as diabetes and heart disease. Omega-3 fatty acids support brain function, including memory, reduce inflammation, and enhance cardiovascular health. The researchers pooled data from 70 randomized clinical trials (RCTs) examining the effect of EPA and DHA from seafood, fortified foods, or supplements, on adults with and without high blood pressure. Yet only 47 percent of those with HTN have the problem under control, according to the analysis. Defined as blood pressure of 140/90 or higher, HTN is a major risk factor for heart attack and stroke, contributing to about 1,000 deaths a day in the United States, reports the Centers for Disease Control (CDC). That’s good news for the 70 million Americans who suffer from hypertension (HTN). Omega-3 fatty acids EPA and DHA–found in fatty fish and fish oil supplements–reduce blood pressure as effectively as lifestyle changes such as exercising more, cutting back on salt, or limiting alcohol, according to a recent meta-analysis published in American Journal of Hypertension.
