Omega-6 oils are the foundation of the body's inflammatory response: more Omega-6 -> more inflammation (prostaglandins are made from Omega 6 [0]). My friend was eating an Omega-6 heavy diet. Omega 6 can't be diluted with Omega-3, the only way to fix the problem is to reduce all polyunsaturated oil consumption.

My breakthrough 'intervention' was frying whole wheat donuts in coconut oil. Coconut oil is brain food for alcoholics.
