Adaptation to high-fat diet, cold had profound effect on Inuit, including shorter height

Researchers have found unique genetic mutations in the Inuit genome that make them more adapted to cold as well as a diet high in omega-3 fatty acids, with the side effect of shorter height. This is the first evidence human populations have adapted to particular diets and differ in their physiological response. While a fish oil diet may be healthful for Inuit, this may not be true for other populations.
