The study comprised 1,014 people who consumed margarine supplemented with daily recommended doses of Omega-3 fatty acids (either 400 mg/day EPA-DHA, 2 g/day ALA, a combination of all three, or placebo) over a 40-month period.
According to the findings of the study, the group receiving a combined supplementation of all three fatty acids experienced a much (84%) lower incidence than those who received placebo.
The study led by Professor Daan Kromhout of Netherlands-based Wageningen University, Division of Human Nutrition, is being published in journal, Diabetes Care, by the American Diabetes Association.
Professor Daan Kromhout said the study showed the protective effect of Omega-3 fatty acids in high-risk patients with diabetes who were on drug treatment for their heart attack.
