It must be noted, however, that omega-6 and omega-3 are not easily metabolized by essential fatty acids people with certain health conditions - e.g. diabetics, alcoholics, certain genetic mutations - or by those consuming a high amount of essential fatty acids trans fats. This difficulty may be overcome essential fatty acids in some cases by supplementing with the omega-6 form GLA, and the omega-3 forms EPA and DHA, all of which are farther down the metabolic chain. [edit] Foods Which Significantly Improve the Omega-6 to Omega-3 Ratio Chia and Flax both provide very good omega-6:omega-3 ratios of approximately 1:3 (skewed toward omega-3), and are therefore capable of significantly improving the omega-6:omega-3 ratio in the traditional western diet. These sources contain omega-3 in Alpha-Linolenic Acid (ALA) form which competes with omega-6 for the delta-6 desaturase enzyme (rate-limiting step), thus may help prevent an excess of the omega-6 metabolyte arachidonic acid (AA) in the body.
