Unlike arachidonic acid (eicosatetraenoic acid, C20:4omega-6, A.A.), eicosapentaenoic acid (C20:5omega-3, E.P.A.) does not induce platelet aggregation in human platelet-rich plasma (P.R.P.), probably because of the formation of thromboxane A3 (T.X.A3) which does not have platelet aggregating properties. Moreover, E.P.A., like A.A., can be utilised by the(More)
In the winter of 1976 an examination of the composition of Eskimo food was carried out in north western Greenland. Duplicate specimens of diets collected from 50 adults, equal numbers of males and females, were analyzed for water, ash, protein, fat, individual fatty acids, cholesterol, and carbohydrate. The results are compared with those of typical Danish(More)
Food specimens have been collected, by means of the double-portion technique, from Greenland Eskimo hunters and their wives, in all seven persons, on seven consecutive days. Their food was found to contain more protein and less carbohydrates than average Danish food and an almost equal amount of fat. Compared with Danish food, the fatty acid pattern of the(More)
Gas-liquid chromatography analyses have been carried out to investigate the composition of esterified fatty acids in the plasma lipids in 130 Greenland Eskimos, compared with those of 32 Greenland Eskimos living in Denmark and of 31 Caucasian Danes in Denmark. While the Eskimos living in Denmark did not differ substantially from other persons living in(More)
Death from cardiovascular disease is rare among Eskimos. Haemostasis was investigated in twenty-one Greeland Eskimos and twenty-one age and sex matched Danish controls. Platelet lipid analysis demonstrated that a high consumption of omega-3 polyunsaturated fatty acids (such as cis 5, 8, 11, 14, 17-eicosapentaenoic acid [C20:5]) by Eskimos increased the(More)
Non-emigrated Greenlanders have a low incidence of acute myocardial infarction (AMI), when compared with age- and sex adjusted death rates for ischemic heart disease in western countries. We find that Greenlanders have plasma lipid levels corresponding to favourable risk factor levels for AMI. This can be attributed to their diet, rich in n-3(More)
