Grass-Fed vs. Grain-Fed Beef
I attended a lecture you gave at CrossfitRoots 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 few 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, etc.. It must be better than most grocery store beef, but if its not that much better, then I'll continue trying to find a 100% grass fed cow.
3. I know you are updating your books, but it would be great if the sources of natural 'paleo' food you have listed were on your web-site and more up to date. I think it could drive a lot of business to vetted paleo approved providers. It would certainly make it easier for us to find them.
Thanks for your time,
My friend Jo Robinson operates this website: http://www.eatwild.com/ which lists grass fed beef producers, not only in Colorado, but also all over the U.S. I have written an extensive paper contrasting grass vs. grain produced beef and their potential effects upon human health and well being. This previously unpublished paper has recently been made available for $19.95 as a PDF file at our website. 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. We plan to update all of our recommended sources for Paleo "friendly" food and include them in a new page at our website.
