Experts reviewed several studies in which more than 100,000 people participated. Little evidence of protection against heart disease has been found. However, despite the lack of protective effects, consumption of oily fish may be recommended as part of a healthy diet, the researchers say. Most studies have focused on dietary supplements rather than on omega-3 intake of fish. The NHS advises, for example, that people should try to eat two servings of fish a week, at best some should be oily fish like salmon, fresh tuna or mackerel.
