EPA (n3) and AA (n6) both compete for use of the delta-5- desaturase enzyme to be synthesized. Increased dietary intake of animal fats alters fatty acid metabolism in favor of inflammation. There are many chronic diseases associated with elevations of this ratio including cardiovascular disease, mood disorders, and cancer. Increasing dietary intake of fish oils, or omega-3 fatty acid containing foods such as flax, chia, oily fish, or walnuts, can shift delta-5-desaturase activity toward the metabolism of the more beneficial n-3 metabolites.
Decreasing intake of animal fats is also recommended.

The higher the AA/EPA ratio, the higher are the levels of cellular inflammation.
An AA/EPA ratio of 1.5 is considered to be ideal, since this is the ratio found in the Japanese population having the greatest longevity and the lowest incidence of cardiovascular disease.
A lower AA/EPA ratio indicates a better balance of “good” and “bad” eicosanoids in your body. The average AA/EPA of Americans is approximately 11, and for patients with inflammatory conditions and neurological disorders, the AA/EPA ratio will be in excess of 20.
