From the posts of Loren Cordain on the Paleodiet list on 6/3/97 and 12/1/97, >>although the lipid content of wild animal marrow (a food commonly used by >>preagricultural man) is generally quite high in total fat percent (~90% >>or >), it contains the lowest saturated fat content (20%) of four >>tissues we have studied (brain, marrow, white adipose tissue and brain). >>Stone age >>diets, although high in animal based food were low in saturated fat, >>even when fattier portions of the carcass were consumed. Our analysis >>of the lipid composition of portions of wild animal carcass which we >>recently presented in Bethesda (1) confirm this concept.
