It's VERY easy to make up your mind following a comment like "he's full of shit", but for anyone reading, I suggest you look at at these two articles by pranarupa:
I was convinced by the advocates for Omega 3's. Then my dogs destroyed my cofffee grinder (used to make flax seed meal), I realized that I'd never noticed a benefit, and stopped.
The modern diet is overloaded with Soybean Oil, an oil which should only be used as biodiesel. It takes years of a low-PUFA diet to obtain all the benefits. Some degree of temporary relief may be provided by Omega-3 supplementation, but this intervention doesn't address the cause of any condition.

To me, Peat's notions on PUFAs and serotonin are the most important ones to grasp.
