A study of the blood lipoids and blood protein in Canadian Eastern Arctic Eskimos

Abstract

Blood samples of 27 Canadian Eastern Arctic Eskimos, collected at random and after fat meals (200 ml. of soya bean oil), were analyzed for lipoid constituents of the blood plasma (i.e., total lipids, neutral fat, total fatty acids, total cholesterol, ester chol., free chol. and phospho-lipins). The combined data fit in with previously reported R.Q.''s in some of these Eskimos and suggest an active and unusual mechanism for the utilization of fats. The difficulties of interpreting these data are briefly discussed. This investigation also included analyses of blood protein; in the Eskimo, at least, it seems that habitual ingestion of enormous amounts of meat does not lead to excess concns. of protein, although it may lead to high concns. of non-protein N.
