Study Identifies Minimum Daily Consumption of Omega-3 Required to Reduce Cardiac Risks
A meta-analysis has concluded that daily intake of at least 250 mg of omega-3 fatty acids is required to reduce sudden cardiac deaths. The review was conducted by researchers at the University of Toronto.
The findings were published on May 31, 2011 in the British Journal of Nutrition online ahead of print.
The researchers looked at 8 studies for their analysis. All of the studies indicated that daily consumption of at least 250 mg of omega-3 fatty acids resulted in a noticeable reduction in sudden cardiac death and in reductions in total fatal coronary events.
Specifically, the researchers noted a 35% reduction in the risk of sudden cardiac death and a 17% decrease in the risk of total fatal coronary events.
The researches stressed that their finding show that a minimum of 250 mg of omega-3 fatty acids a day is required to obtain the desired heart health effects. The 2010 United States Dietary Guidelines recommends consumption of 8-12 ounces of seafood per week, which would provide an average consumption of 250mg of omega-3’s per day.
A number of other benefits have been linked to omega-3’s, including reducing the risk of age-related cognitive decline, improving mood and reducing the risk of age-related vision loss.
You can increase your omega-3 intake by eating more fatty fish such as mackerel, salmon and cod. If you don’t care for fish, or are concerned about high mercury levels that may be present in fish, a high quality fish oil supplement will work as well. Look for one that’s certified for purity and potency so you can be sure it doesn’t contain dangerous contaminants.
