1976年冬天，在格陵兰岛西北部研究了爱斯基摩人食物的组成。从50名成年人，男性和女性的相同数量的饮食重复标本，进行了分析的水，灰分，蛋白质，脂肪，个别脂肪酸，胆固醇和碳水化合物。结果与典型的丹麦饮食。海豹和鱼是爱斯基摩人的主要食物。爱斯基摩人和丹麦人的食物有明显的差异，爱斯基摩人的食物中多不饱和脂肪酸含量较高，与饱和脂肪酸的比值为0.84，而丹麦人为0.24。多不饱和脂肪酸在爱斯基摩人中主要是亚麻酸类（n-3），在丹麦人中主要是亚油酸类（n-6）。单烯棕榈油酸和油酸以外的高爱斯基摩饮食，但在丹麦可以忽略不计。结果与爱斯基摩人先前的血脂检查有关。格陵兰爱斯基摩人缺血性心脏病的罕见性可能是由长链多不饱和脂肪酸的抗血栓形成作用解释的，特别是富含海洋油的饮食中普遍存在的二十碳五烯酸。
Composition of Eskimo food was studied in winter 1976 in northwestern 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. Results are compared with those of typical Danish diets. Seal and fish are predominant Eskimo food. Marked differences between Eskimo and Danish food were found. The Eskimo diets were richer in polyunsaturated fatty acids, the ratio to saturated fatty acids was 0.84 as compared with 0.24 in Danes. Polyunsaturated fatty acids were predominantly of the linolenic class (n-3) in Eskimos and the linoleic class (n-6) in Danes. Monoenes other than palmitoleic and oleic acids were high in Eskimo diets but negligible in Danish. Results are related to previous examinations of plasma lipids in Eskimos. Rarity of ischemic heart disease in Greenland Eskimos may be explained by antithrombotic effect of long-chained polyunsaturated fatty acids, especially eicosapentaenoic acid prevalent in diets rich in marine oils.
