Despite a Diet High in Fat, Inuit Peoples Are Not

Despite a diet high in fat, Inuit peoples are not prone to high blood pressure or cholesterol, and are less likely to have heart disease. Why?

A) They have adapted to a diet high in saturated fat.
B) The unhealthy consequences of a high fat diet are nullified by solar radiation, more common at the northern and southern poles.
C) The Inuit diet is low in saturated ('bad') fats, and high in Omega-3 polyunsaturated ('good') fats.
D) They have a special gene that instructs the body to convert fat into energy.
E) Actually, their diet is very low in fat altogether.
