“…(Bjorkstene et al, 1975). Evenki men and women have substantially lower' total cholesterol levels than all other arctic populations presented in Table 8 except for the sample of Corcoran et al (1937). Evenki triglyceride levels, on the other hand, are lower than those of the Nenets 't tests demonstrated significant differences (P < 0.01) be- and Lapps, but higher than those in Eskimos described by Feldman et al (1972).…”

This study examines serum lipid levels (total, HDL and LDL cholesterol, and triglycerides) among the Evenki reindeer herders of Central Siberia. Cholesterol and triglyceride levels among the Evenki are low, even relative to other indigenous arctic and herding populations. Total and LDL cholesterol levels are higher in women, while HDL and triglyceride levels are comparable between the sexes. Additionally, residence location (i.e., herding brigade vs. central villages) has a significant influence on men's but not women's total and LDL cholesterol levels. Low lipid levels among the Evenki appear to reflect the maintenance of a traditional lifestyle with high levels of energy expenditure and relatively low levels of fat consumption. Sex differences in lipid levels may be partly attributable to differences in activity patterns, as women have significantly lower levels of energy expenditure than men. © 1994 Wiley-Liss, Inc.

“…Over the past 64 y, anthropological research has consistently demonstrated relatively low serum cholesterol and triacylglycerol levels among indigenous populations that derive the majority of their diet from animal products (Bang & Dyerberg, 1980;Biss et al, 1971;Corcoran & Rabinowitch, 1937;Day et al, 1976;Eaton et al, 1988a;Scott et al, 1958;Shaper et al, 1961;Wilber & Levine, 1950). Further, a low incidence of coronary heart disease among the Inuit and other indigenous populations of the circumpolar regions has been recognized for at least 30 y from autopsy studies (Arthaud, 1970;Gottman, 1960;Lederman et al, 1962), analyses of death certificates (Bjerregaard & Dyerberg, 1988;Middaugh, 1990;Young et al, 1993) and clinical data (Bang & Dyerberg 1980;Kromann & Green, 1950).…”

The paradoxical nature of hunter-gatherer diets: meat-based, yet non-atherogenic

et al. 2002

Objective: Field studies of twentieth century hunter-gathers (HG) showed them to be generally free of the signs and symptoms of cardiovascular disease (CVD). Consequently, the characterization of HG diets may have important implications in designing therapeutic diets that reduce the risk for CVD in Westernized societies. Based upon limited ethnographic data (n ¼ 58 HG societies) and a single quantitative dietary study, it has been commonly inferred that gathered plant foods provided the dominant energy source in HG diets. Method and Results: In this review we have analyzed the 13 known quantitative dietary studies of HG and demonstrate that animal food actually provided the dominant (65%) energy source, while gathered plant foods comprised the remainder (35%). This data is consistent with a more recent, comprehensive review of the entire ethnographic data (n ¼ 229 HG societies) that showed the mean subsistence dependence upon gathered plant foods was 32%, whereas it was 68% for animal foods. Other evidence, including isotopic analyses of Paleolithic hominid collagen tissue, reductions in hominid gut size, low activity levels of certain enzymes, and optimal foraging data all point toward a long history of meat-based diets in our species. Because increasing meat consumption in Western diets is frequently associated with increased risk for CVD mortality, it is seemingly paradoxical that HG societies, who consume the majority of their energy from animal food, have been shown to be relatively free of the signs and symptoms of CVD. Conclusion: The high reliance upon animal-based foods would not have necessarily elicited unfavorable blood lipid profiles because of the hypolipidemic effects of high dietary protein (19 -35% energy) and the relatively low level of dietary carbohydrate (22 -40% energy). Although fat intake (28 -58% energy) would have been similar to or higher than that found in Western diets, it is likely that important qualitative differences in fat intake, including relatively high levels of MUFA and PUFA and a lower o-6=o-3 fatty acid ratio, would have served to inhibit the development of CVD. Other dietary characteristics including high intakes of antioxidants, fiber, vitamins and phytochemicals along with a low salt intake may have operated synergistically with lifestyle characteristics (more exercise, less stress and no smoking) to further deter the development of CVD.

“…The apparent low incidence of atherosclerosis and ischaemic heart disease among the Inuit has inspired research on the biological effects of n-3 polyunsaturated fatty acids for decades (Corcoran & Rabinowitch, 1937;Wilber & Levine, 1950;Scott et al, 1958;Bang & Dyerberg, 1972). The low incidence has been con®rmed by autopsies (Lederman et al, 1962;Arthaud, 1970;Newman et al, 1993Newman et al, , 1995 and by studies of death certi®cates (Bjerregaard & Dyerberg, 1988;Middaugh, 1990).…”

The associations of a marine diet with plasma lipids, blood glucose, blood pressure and obesity among the Inuit in Greenland

Objective: To analyse the associations between the intake of ®sh and marine mammals and risk factors for cardiovascular disease, ie lipid pro®le, fasting blood glucose, blood pressure and obesity, in a population whose average consumption of n-3 fatty acids is high compared with Western countries. Design: Information was obtained from a population survey in Greenland: interview data, clinical data and fasting blood samples were obtained from a random sample of Inuit from three towns and four villages. Subjects: Two-hundred and ®fty-nine adult Inuit (74% of the sample). Results: Marine diet was positively associated with serum high-density lipoprotein (HDL) and blood glucose and inversely with very-low-density lipoprotein (VLDL) and triglyceride. Association with low-density lipoprotein (LDL), diastolic and systolic blood pressure, waist ± hip ratio and body mass index were inconsistent and not statistically signi®cant. The pattern was similar within groups with low, medium and high consumption of marine food. Conclusions: There are statistically signi®cant associations between the consumption of marine food and certain lipid fractions in the blood also in this population with a very high average intake of marine food. The observation that blood glucose is positively associated with marine diet in a population survey is new and should be repeated. There was good agreement between the results for the reported consumption of seal and those for the biomarkers.
