Part: They are part of healthy diet best obtained by a diet of unprocessed grains (not wheat or corn) like brown rice or quinoa, vegetables (not potatoes), beans, fruit, nuts like walnuts/pecans/almonds), or seeds + wild caught game (fish or free range chicken or cage free eggs). This is the correct food intake for the human biology. www.thepmc.org.

Good for heart: There are many observational studies that suggest that high consumption of omega 3 reduces risk of cardiovascular deaths including sudden deaths . In concentrated form as ethyl ester it lowers triglycerides.
