Feces fossils lend new insights into connection between Native-Americans, diabetes
Date:7/23/2012

Why do Native Americans experience high rates of diabetes? A common theory is that they possess fat-hoarding "thrifty genes" left over from their ancestors genes that were required for survival during ancient cycles of feast and famine, but that now contribute to the disease in a modern world of more fatty and sugary diets.

A newly published analysis of fossilized feces from the American Southwest, however, suggests this "thrifty gene" may not have developed because of how often ancient Natives ate. Instead, researchers said, the connection may have come from precisely what they ate.

The research, which appears in the latest edition of the journal Current Anthropology, suggests that the prehistoric hunter-gatherer civilizations of the Southwest lived on a diet very high in fiber, very low in fat and dominated by foods extremely low on the glycemic index, a measure of effects food has on blood sugar levels. This diet, researchers said, could have been sufficient to give rise to the fat-storing "thrifty genes."

"What we're saying is we don't really need to look to feast or famine as a basis for (the genes)," said Karl Reinhard, professor of forensic sciences at the University of Nebraska-Lincoln's School of Natural Resources and the study's lead author. "The feast-or-famine scenario long hypothesized to be the pressure for 'thrifty genes' isn't necessary, given the dietary evidence we've found."

Natives have some of the highest rates of Type 2 diabetes of any group and are more than twice as likely to develop the disease as are Caucasians. The notion the gene's origin goes back to feast-and-famine cycles among prehistoric hunter-gatherer ancestors has been discussed for nearly a half-century.

To fully understand the basis of the high rates, Reinhard said, "one has to look at the best dietary data one can find. That comes from coprolites (the official term for fossilized feces). By looking at coprolites, we're s
