They also play an important role in skin and coat health. Forages like fresh pasture are high in omega 3 and low in omega 6. Grains are high in omega 6 and low in omega 3. Sunflower oil and corn oil are very high in omega 6 and contain virtually no omega 3. Canola oil contains a beneficial amount of both omega 3 and 6.
