Below we have listed information concerning Omega 3 and its benefits for a healthy heart. It shows you why eating a regular intake of delicious oily fish can make a difference.
Systematic reviews of available literature shows evidence that long chain omega-3 fatty acids, the beneficial component ingested by eating fish or taking a fish oil supplements, reduce heart attacks and other problems related to heart and blood vessel disease in persons who already have these conditions, as well as their overall risk of death. Although omega-3 fatty acids do not alter total cholesterol, HDL cholesterol, or LDL cholesterol, evidence suggests that they can reduce levels of triglycerides, a fat in the blood that causes heart problems.
The Journal of the American Medical of Association, investigators from the Harvard School of Public Health reported that women who consumed more fish and fish oil (omega-3 fatty acids) significantly reduced their risk of heart disease.
In this study, among 85,000 women enrolled in the Nurses' Health Study, those who ate fish 2 to 4 times per week reduced their risk of coronary heart disease by 30%, compared to women who rarely ate fish.
Similarly, investigators from Massachusetts General Hospital reported that men in the Physicians' Health Study (men who had no evidence of prior coronary heart disease) who consumed omega-3 fatty acids had a significantly reduced risk of heart attacks, heart failure & sudden death.
The evidence that omega-3 fatty acids benefits the heart, thanks to these two studies, is now nearly irrefutable.
While a major benefit of fish oil in these studies appears to be a reduction in sudden death from cardiac arrhythmias, omega-3 fatty acids also appear to reduce triglyceride levels, reduce blood pressure, and stabilize the blood clotting mechanisms. Thus, there are several pathways in which fish oil can potentially benefit the cardiovascular system. The evidence that omega-3 fatty acids benefits the heart, thanks to these two studies, is now nearly irrefutable, and will no doubt become widely accepted by the medical community. (The American Heart Foundation, however, is waiting for yet more evidence before changing its official recommendations.)
AHRQ Evidence Reports Confirm That Fish Oil Helps Fight Heart Disease
A review by AHRQ found evidence indicating that fish oil can help lower high blood pressure slightly, may reduce risk of coronary artery re-blockage (Heart Attacks) after angioplasty, may increase heart exercise capability among patients with clogged arteries, and may possibly reduce the risk of irregular heart beats particularly in individuals with a recent heart attack.
"These findings will help health care professionals and the public understand which benefits of omega-3 fatty acids have been scientifically proven and pinpoint areas where additional evidence is needed," said Carolyn M. Clancy, M.D., AHRQ's Director. "Translating scientific evidence into information that can be used to improve health and heath care is key to AHRQ's mission."
AHA Recommendation
Omega-3 fatty acids benefit the heart of healthy people, and those at high risk of or who have cardiovascular disease.
Improve Heart Health, we recommend eating fish (particularly fatty fish) at least two times a week. Fish is a good source of protein and doesn't have the high saturated fat that fatty meat products do. Fatty fish like mackerel, lake trout, herring, sardines, albacore tuna and salmon are high in two kinds of omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
