Indeed,an epidemic of obesity is now spreading into ethnic groups from Siberia to Peru,as quickly as grocery stores open their doors.But although fast food is becoming the universal diet,not all people respond alike to this nutritional transition.For example,unlike the Pima,the Evenki reindeer herders and other indigenous peoples of Siberia have very high metabolisms,an adaptation to the cold that allows them to convert fat into energy efficiently.When the Soviet Union collapsed in the 1990s,many Siberians abandoned traditional lifestyles and diets.They too became obese and developed heart disease but in a different way from the Pima:The Evenki retained low levels of cholesterol and diabetes but developed high blood pressure,as University of Oregon,Eugene,anthropologist J.Josh Snodgrass reported recently in the American Journal of Physical Anthropology.In terms of disease risk,“the Pima are the mirror image of the Siberians,” says Leonard.
事实上,肥胖像流行病一样在世界上的各种民族中间变得更加广泛,从西伯利亚到到秘鲁无不如此,它的速度就像在你隔壁开家小杂货店一样快,但是尽管快餐正在成为全球的桌上餐,也不是所有的人都会跟着这种营养变化的潮流走,比如,与皮玛人不同,善于养殖驯鹿的伊文基人和其它西伯利亚人都有很强的新陈代谢,他们能很快地把脂肪转化为能量,这种能力使他们对冰冷的环境有较强的适应能力.上世纪前苏联解体时,许多西伯利亚人放弃了传统的生活习惯和饮食习惯,他们变得肥胖起来,容易罹患心脏病.美国俄罗冈大学人类学家J约什·斯诺德格拉斯最近在美国生物人类学杂志上发表文章报道伊文基人保留了低水平的胆因醇和血糖,可是容易患高血压,这与皮玛人的现状大不相同.从是否容易患病的角度来看,李奥纳多认为“皮玛人是西伯利亚人应该借鉴的一面镜子”.
