However, what you say contradicts with what some researchers say, that plant source omega-3 is enough.
Also, there are many examples of perfectly healthy people that are strictly vegan.[/b]
Don't think for a minute that researchers are immune to bias (personal, ethical, commercial) in their work. While I accept that such bias may exist in what I've read up on, I believe that all things considered there's more reason to be doubtful of pro-veg* research than others, simply because the ethical side of food research can and does blind even the most professional of researchers to the truth, either consciously or unconsciously. That isn't to say that all pro-veg* research is baseless and fraudulent, of course.
There is no "perfectly healthy" as you describe it. I have no doubts that a person today can live a fully vegan life without wasting away too prematurely... and compared to the SAD (Standard American Diet), veganism is an incredible step in the right direction, but just because vegans are healthier than Joe Burgereater does not mean that they're healthiest. Like I said, the body converts ALA to EPA and DHA. It's not a question of whether vegans are getting those long-chain PUFAs or not (they are), but of whether they're getting an optimal amount, and everything I've read and seen and heard suggests: no, they're not. Unless they supplement with fish oil or synthesized fatty acids, and either of those options means that it's no longer vegan or natural. The problem with Vitamin B12 is even more prominent: you have to eat animal products or get it synthesized from a pill, or you will develop permanent brain damage. Period!
