Additional information regarding the benefits of omega fatty acids:  

Medical research shows omega fatty acids have health benefits.
Scientists made one of the first associations between omega-3 fatty acids and good health while studying the Inuit (Eskimo) people of Greenland in the 1970s. As a group, the Inuit suffered far less from certain diseases (coronary heart disease, rheumatoid arthritis, diabetes mellitus, psoriasis) than their European counterparts. Yet their diet is very high in fat from eating whale, seal, salmon and other fish.

Eventually researchers realized that these foods were all rich in omega-3 fatty acids, which provided real disease-countering benefits.

Omega 3s help prevent discomforts related to inflammation.
Rheumatoid arthritis, lupus, Raynaud's disease and other autoimmune diseases greatly decrease quality of life. Diets high in omega-3 fatty acids (such as fish oils) have been shown to increase survival in people with autoimmune diseases. This is probably because the omega-3s help the arteries - as well as many other parts of the body - stay inflammation free. EPA and DHA are successful at this because they can be converted into natural anti-inflammatory substances called prostaglandins and leukotrienes, compounds that help decrease inflammation and pain.

In 1998, an exciting review of well-designed, randomized clinical trials reported that omega-3 fatty acids were more successful than a placebo ("dummy drug") in improving the condition of people with rheumatoid arthritis. The research also showed that getting more omega-3 fatty acids enabled some participants to reduce their use of nonsteroidal anti-inflammatory drugs (NSAIDs). .
