Comparative Absorption and Lymphatic Transport of (ω-3) Eicosapentaenoic Acid, (ω-6) Arachidonic Acid, and (ω-9) Oleic Acid
There is a rapidly expanding literature on the dietary and metabolic effects of the ω-3 class of fatty acids, which include, among others, linolenic, eicosapentaenoic, and docosahexaenoic acids (Goodnight et al, 1982; Holman, 1982; Willis, 1981). Interest in this area has been heightened by the finding that population groups consuming greater quantities of fish and other marine animals, which are richer in (ω-3 fatty acids, have a low incidence of ischemie heart disease. These include Greenland Eskimos (Bang and Dyerberg, 1980), coastal-dwelling Turks (Yotakis, 1981), and Japanese residing in fishing villages (Hirai et al., 1980). In general, these populations have lower levels of fasting very-low-density and low-density lipoprotein cholesterol, increased levels of high-density lipoprotein cholesterol (Bang and Dyerberg, 1972), and a prolonged bleeding time (Dyerberg and Bang, 1979; Goodnight et al., 1981). These effects are largely attributed to the intake of marine fats, which contain, in addition to “common” fatty acids, higher levels of ω-3 fatty acids than are found in Western-type diets (Bang et al., 1976).
