Daily doses of omega-3s of at least 250 milligrams are required to reduce the risk of sudden cardiac death and other heart conditions, says a new review and meta-analysis.
According to findings published in the British Journal of Nutrition, at least 250 mg of the long-chain omega-3 fatty acids (LCFA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), was associated with a 35 percent reduction in the risk of sudden cardiac death.
In addition, such doses were associated with a ‘near-significant’ 17 percent decrease in the risk of ‘total fatal coronary events’, according to a team of researchers from academia and industry.
“Thus, the intake of 250 mg omega-3 LCFA per day may, indeed, be a minimum target to be achieved by the general population for the promotion of cardiovascular health,” wrote authors led by Kathy Musa-Veloso from Cantox Health Sciences International.
The study’s authors were affiliated with Cantox, the University of Toronto, the Global Organization for EPA and DHA Omega-3s (GOED), Denomega Nutritional Oils AS, Ocean Nutrition Canada, and Monsanto.
The European Food Safety Authority (EFSA) concluded in 2009 that 250mg should be the labeling reference intake value for long-chain omega-3 fatty acids.
In the US, the recently released 2010 Dietary Guidelines for Americans did not include specific EPA/DHA recommendations, but instead recommended consumption levels of seafood of 8-12 ounces per week, “which provide an average consumption of 250 mg per day of EPA and DHA”.
The new meta-analysis and review sought to test such recommendations. The reviewers identified 8 prospective studies to include, and these indicated that consuming at least 250 mg was associated with a significant reduction in sudden cardiac death and near-significant reductions in the risk of total fatal coronary events.
Researcher said that the results suggest that 250mg/day EPA+DHA should be considered a minimum, not an optimum, level of consumption.
