Check out this video from Udo - http://www.videoclipstream.com/t-v/udo/videowindow.html
He addresses conversion rates a little bit, but mostly does not like fish oil because of the way they are processed. So omega 3 from a seed is the healthiest way to consume it.
And here is an article pertaining to fish oil vs. plant oil - http://www.vegetarian.org.uk/factshe...hfactsheet.pdf
It does not deal with conversion rates so when it says things like plant oil contains much more omega 3 then fish oil, it isn't taking into account what kind of fatty acid. So it is basically about the health concerns of fish oil.
What do you guys think about this?
