Grass-Fed vs. Grain-Fed Beef

Grass Fed Beef | The Paleo Diet

Dr. Cordain,

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,

Scott

Dr. Cordain’s Response

Hi Scott,

My friend Jo Robinson’s website, Eat Wild 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.

Cordially,

Loren Cordain, Ph.D., Professor Emeritus
