New ground-breaking genetics research explains the high incidence of type 2 diabetes in the Greenlandic population, based on blood samples from 5,000 people or approximately 10% of the population. “Several epidemiological studies have looked at the health implications of the transition from life as sealers and hunters in small isolated communities to a modern lifestyle with appreciable dietary changes. Perhaps the gene variant which has been identified can be interpreted as a sign of natural selection as the traditional Greenlandic diet consisted primarily of protein and fat from sea animals,” one researcher said.
