I attended a lecture you gave at CrossFit Roots in Boulder and have also read your book The Paleo Diet.
My wife and I have been trying to purchase a quarter cow and have been researching farms in the area. I know 100% Grass Fed is better, but they are not as easy to find so I have a couple questions:
1. Do you have any recommended resources for 100% Grass Fed beef in Colorado?
2. Have you done any studies on the fat profile difference between 100% grass fed beef and grass fed beef that is “corn finished?” I’m curious on whether its 20% worse, 50% worse, or… It must be better than most grocery store beef, but if it’s not that much better, then I’ll continue trying to find a 100% grass fed cow.
Thanks for your time,

My friend Jo Robinson’s website, lists grass-fed beef producers, not only in Colorado, but also all over the U.S. Our partners, D’Artagnan, are the leading purveyors of natural, free-range meats that ship all over the country as well.
I have written an extensive paper contrasting grass vs. grain produced beef and their potential effects upon human health and well being in The Nutritional Differences Between Grain and Grass-Fed Beef. The paper is 39 pages long contains over 7,700 words, 92 references, 7 tables and 10 figures. My manuscript represents the single most comprehensive review to date comparing the potential health effects of grass and grain produced beef.
