Is grass fed beef realy paleo. I know it is. Lets see it from some other view. Modern beef is highly cultivated so it as that much fat and meat and produces so much milk.
In old days animals where more lean and always had to run to be safe from the predator. I think cattles come from asia. There the cows are still very lean.
How is it possible to include such thoughts. Is there lean cow meat? Is there a kind of paleo grass fed cow? A ancient cow? An original cow?
