The American Heart Association (AHA) Summary of Recommendations for Omega-3 Fatty Acid Intake as of May 7, 2009.
Patients without documented coronary heart disease (CHD)
Eat a variety of fatty fish at least twice a week.
Patients with documented CHD
Consume about 1 gram of EPA+DHA per day, preferably from fatty fish.
Patients who need to lower triglycerides
2 to 4 grams of EPA +DHA per day, provided as fish oil capsules and always under physician care.
The AHA report suggest that patients taking more than 3 grams of omega-3 fatty acids from capsules can be at increased risk of internal bleeding and suppressed immune system.
What do epidemiological and observational studies show?
The Good News: Epidemiologic and clinical trials have shown that omega-3 fatty acids reduce CVC incidence. Large-scale epidemiologic studies suggest that people at risk for coronary heart disease benefit from consuming omega-3 fatty acids from plants and marine sources.
However, the ideal amount to take isn't clear, and neither the AHA or the Institute of Medicine recommend more than 500 mg per day (3,500 mg per week) for disease prevention. Evidence from a few prospective secondary prevention studies suggest that taking 2 grams of EPA / DHA per day (fatty fish or supplements) reduces deaths from heart disease. Other retrospective studies suggest not.
Fish Oil is the largest selling product in the supplement industry and agressive marketers are not shy about recommending 2 or more grams of EPA/DHA a day for disease prevention. The American Heart Association clearly recommends physician care for those taking over 3 grams of Omega-3 EPA /DHA on a daily basis.
We at Biosyntrx strongly support fish consumption and fish oil supplementation, but it is not the be-all-end-all magic bullet that some suggest. Excessive amounts of supplemental fish oil may inhibit the body's ability to mount a lifesaving inflammatory response if needed.
Good health and certainly eye health is dependent on adequate consumption of the the full-spectrum of nutrients including fatty acids, portion and weight control, shades when in the sun, committment to regular exercise and loving friend and family relationships.
