Changes in Lipid and Lipoprotein Levels and Body Weight in Tarahumara Indians after Consumption of an Affluent Diet

Abstract
Major new public health problems occur in developing countries as they become more affluent and change their traditional dietary patterns. To study this phenomenon in microcosm, we substituted an "affluent" diet for the traditional diet of a group of Tarahumara Indians, a Mexican people known to consume a low-fat, high-fiber diet and to have a very low incidence of risk factors for coronary heart disease.
