My understanding (from investigating this a couple years ago) is that grass-fed beef, while higher in O3's than corn-fed beef, is not a particularly significant source of dietary O3.
I think that is accurate. I only meant to use beef as an example of how our food supply has changed, not to suggest that beef is any sort of good source for omega 3s.
Correct me if I'm wrong, but it's not just that grass-fed beef is higher in Omega 3, but lower in Omega 6. So it's not just about Omega 3 intake, but the ratio between the two.
