Little known factoid.... People from foreign countries actually seem to prefer our grain fed beef. I worked for a company that did international business, and I was quite often told that our beef tasted better. And have even heard people comment that the beef tastes better in America because it is grain fed.
I think much like how 85% lean beef tastes better than 95% lean beef (to some people at least) the increased fat content actually enhances the flavor. Just my 2 cent observation, but perhaps that's why that was put into the article.
In any case, it still comes down to omega 3 : 6 balance. The balance is more important than some arbitrary number of grams of omega 3.
