Omega-3 fatty acids have been the subject of thousands of scientific studies. In the 1970s, a study found that a tribe of Inuit Eskimos in Greenland had almost no cardiovascular disease. Why? Because of the great quantities of fatty seafood they ate. It was a turning point in the scientific understanding of the importance of the benefits of the long chain fatty acids DHA and EPA found in omega-3s.
An important study published recently in the "Journal of the American Medical Association," concluded that adequate omega-3 intake was associated with a 36% decrease in death from coronary artery disease and a 17% fall in the risk of death from any cause. This Harvard study also concluded that omega-3 fats are important for optimal brain health. This study, like previous information, suggested that the optimal dose for cardiovascular benefit is at least 500 mg to 1000 mg of EPA plus DHA per day. Other recent studies have shown that increased omega-3 appears to improve mood and brain function, as well as reduce the risk of sudden cardiac death in adults.
