The study in question involved 7,000 participants who had been diagnosed with heart failure, half of whom were given a daily capsule of omega-3 in addition to their other daily medications and half of whom were given a placebo. The volunteers were followed for around four years, during which 27 per cent of the group taking omega-3 died of heart failure or were admitted to hospital with cardiovascular issues, compared to 29 per cent in the placebo group.
The study has added further weight to previous studies suggesting the benefits of omega-3 and in light of the findings Dr. Douglas Weaver, president of the American College of Cardiology believes that changes will soon be seen in U.S. guidelines so that it is recommended heart patients take supplements or eat more fish.
As it stands public health organisations recommend that individuals try to eat fish twice a week. Oily fish such as mackerel, salmon and anchovies are particularly good sources of omega-3 though those who do not like fish can obtain omega-3 through supplements, walnuts, flaxseed and various vegetables such as spinach, broccoli and cauliflower.
