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.
与温带气候地区的居民相比，饮食中糖类吸收障碍在北极地区的原住民中更为常见。据推测，北极地区天然外源糖种类有限，且根据“蛋白质-脂质”代谢类型，北极地区原住民传统饮食中这些糖的含量较低，这削弱了对二糖酶多样性的选择。
