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. The combined
>>total amount of polyunsaturated and monounsaturated fat in wild animals
>>would have almost always equaled or exceed the saturated fat content.
