An article in USA Today says that fish oil supplements don't do anything to prevent heart attacks; yet, sales of it have gone up over the years with that particular promise in mind.
The researchers reviewed 20 well-designed clinical trials that looked at the health outcomes of people taking omega-3 polyunsaturated fatty acid supplements derived from fish oils. The trials dated from 1989 to 2012 and included 68,680 people who were studied for at least a year. They found no statistically significant association between all deaths, cardiac-related deaths, sudden deaths, heart attacks and strokes among people taking the supplements. The review was led by Evangelos Rizos, a professor of medicine at the University Hospital of Ioannina in Greece.
The medical world long ago noted that societies in which diets were high in fatty fish such as salmon, sardines, mackerel and others had lower rates of heart disease. A large 1989 study found that men who had already had a heart attack and changed their diets to include more fatty fish rich in omega-3 polyunsaturated fatty acid were 29% less likely to die in the next two years. Because of these and other findings, many medical groups suggest that people at risk for heart disease either increase their fatty fish intake or take omega-3 supplements.
The message Americans may not want to hear is that eating healthy foods, not taking pills, is what helps heart health, says Richard Karas, director of the preventive cardiology center at Tufts Medical Center in Boston.
True enough. In this case it only shows that pills don't work as well as a healthy diet. The message here is that it is far better to eat more fish containing omega-3 polyunsaturated fatty acid. More important, well-cooked fish is delicious and tastes wonderful.
