(WebMD) The benefits of omega-3s in fighting heart disease may be only so-so, according to a new review of research on the fatty acids found in fish and some plant and nut oils.
The study doesn’t rule out an important effect of omega-3 fatty acids on health, but the results indicate that the evidence behind the fishy fats is less conclusive than previously thought.
Eating foods rich in omega-3 fatty acids, such as fatty fish and some plant and nut oils, such as olive and walnut, is thought to lower the risk of heart disease, and several public health organizations have recommended that people to eat more oily fish, such as salmon and tuna.
But in a review of 89 studies that measured the effect of omega-3 fatty acids on heart attack, death, cancer, and strokes, researchers didn’t find any clear benefit of omega-3s in reducing the risk of these health hazards.
