Diabetes and Mexicans: why the two are linked.

Abstract: Obesity and diabetes were probably rare before the advent of agriculture. Our ancestors, hunters and gatherers for millennia, had varied but unpredictable diets. Studies of hunter-gatherers of the 20th century suggest that animal sources dominated our ancient food basket, with plants (fruits, vegetables, and nuts) providing only 20% to 40% of total energy (1). Modern and presumably ancient hunter-gatherer populations, despite a high-fat, high-protein diet, were free of the signs and symptoms of noncommunicable diseases a paradox. Perhaps energy needs were not always met, thus keeping body sizes in check; also, the relative lack of salt and simple carbohydrates, a mix of saturated and good fats, plenty of fiber, abundant micronutrients, a vigorous and active life, and less stress than we now endure may explain this finding. With the food supply uncertain, one would expect individuals with thrifty genotypes genotypes that increase the ability to turn food to fat to have a survival edge.
