Disorders of dietary sugar assimilation occur more often among native people of the Arctic then in temperate climate inhabitants.
It is hypothesized that the limited variety of natural exogenous sugars in the Arctic, and their low content in the traditional diets of native northerners in accordance with a “protein-lipid” type of metabolism weakened selection, favoring diversity of disaccharidase enzymes.
