Omega 3 fatty acids from fish has been shown in epidemiological and clinical trials to reduce the incidence of heart disease by lowering cholesterol. Large-scale epidemiological studies suggest that individuals at risk for coronary heart disease benefit from the consumption of fish oil, as it is high in omega 3 fatty acids.
The American Heart Association updated its advice on fish oil supplements and the full article was published in Circulation 106:2747-2757, 2002. Here’s the short version of what they recommend :
People without documented coronary heart disease
Eat a variety of (preferably oily) fish at least twice a week. Include oils and foods rich in alpha-linolenic acid (flax seed oil, canola oil, and soybean oil; flax seed and walnuts)
People with documented coronary heart disease
Consume approximately 1 gram of EPA+DHA per day, preferably from oily fish. EPA+DHA supplements could be considered in consultation with a physician.
People needing triglyceride-lowering
Two to four grams of EPA+DHA per day provided as capsules such as fish oil or omega 3 supplements under a physician's care

In addition, the data support inclusion of vegetable oils (eg, soybean, canola, walnut, flax seed) and food sources (e.g., walnuts, flax seed) high in alpha-linolenic acid in a healthy diet for the general population. Consumption of a variety of fish is recommended to minimize any potentially adverse effects due to environmental pollutants and, at the same time, achieve desired heart health outcomes.
