Fish oil supplements do not prevent heart attacks or strokes in those with type 2 diabetes, according to research published in the New England Journal of Medicine. Researchers gave 15,480 type 2 diabetes patients without heart disease fish oil supplements or a placebo and compared cardiovascular event occurrences, including heart attacks, strokes, or death from heart disease. The results showed no significant difference between groups for cardiovascular disease events. These results support previous findings that showed no benefit of omega-3 fatty acid supplementation for heart disease prevention. The authors suggest removing recommendations for fish oil supplements in current clinical guidelines.
