“While most Americans eat way too much of the the omega-6 oils found in meats and most vegetable oils, they suffer a relative deficiency of the omega-3 oils — a situation that is associated with an increase risk for heart disease and about 60 other conditions including cancer, arthritis, stroke, high blood pressure, skin diseases, and diabetes.

Particularly important to good health are the longer chain omega-3 fatty acids such as eicosapentaenoic acid (EPA) and docosahexanoic acid (DHA) found in fish, especially cold-water fish such as salmon, mackerel, herring, and halibut. Although the body can convert alphalinolenic acid, a short-chain omega-3 fatty acid, from flaxseed oil it is much more efficient to get them from fish oils. Furthermore, there is evidence that many people have a difficult time converting alpha linolenic acid to EPA and DHA.” This quote is from DoctorMurray.com.
