Fish, Fish Oil, Omega 3 fatty acids and Heart Disease

Omega 3 fatty acids from f.i.s.h 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
