The benefit of eating fish isn’t an entirely new discovery. Scientists have known for decades that fish oils have positive health effects. Studies in the 1970s showed that the Inuit had a much lower incidence of cardiovascular disease than most Europeans, as did people who ate a Mediterranean diet. The Japanese, meanwhile, have one of the highest life expectancies. All these diets are particularly rich in omega-3 fatty acids—found in large amounts in most fish. Try one of these healthy fish recipes to give your omega-3s a boost—your heart will thank you!
