You, sir, are correct. I would have to be pretty darn hungry to try that. I eat rare meat, but I have yet to eat any raw, and I have not tried cracking bones open. Well, I would not be even slightly surprised to learn that the composition of our meat animals is wrong, after all, we've done the same things to their diets that we have done to ours. I concede that it is possible that our ancestors' prey animals had a lower concentration of saturated fats in them. The thing I'm not buying is the old "fat makes you fat" argument. Take care, John Pavao ---------- Obvously, you have never tried... Bone marrow is one of my preferred parts (raw). It shouldn't be very difficult to break a bone and extract its marrow, even with the simplest stone tools. Moreover, I am not claiming that bone marrow is the only tissue that contributes to a low saturated fat intake (in percentage). It seems that the fat composition of wild animals is different from the fat composition of domestic animals, although I don't have numerical data to support this claim, and, until the article has been published, I have to trust Loren Cordain's post on the Paleodiet list.
