Several studies have found omega-3s in the bloodstream of vegans (I'll try and post links later), which suggest it endogenous production of it's metabolites actually occurs at a low level.

While this doesn't get you into the recommend blood levels of omega-3 oils (it's mostly suprising because it's been found at all, and consistently), I have not seen a non-drastic method for meeting the amounts of omega three that the science reccomends, vegan or not.

Omega fat science is quite out of whack with the dietary recomendations commonly made. If you do the math, in order to acheive the ratios that are described in most papers I've read, one would need to forgo all omega 6 sources (olive oil, tofu, many other things), or consume unrealistic amounts of omega-3 oil each day to offset them. (I once calculated it to be in the region of a pint of omega-3 rich oil a day)

I'm equally mystified, but about the whole thing.
