As Stefansson points out in "Hunters of the Great North" (Harcourt, Brace
& Co.,1922), the Inuit he met were in a period of great stress.  Their
way of life had been disturbed by the white man's trade goods and hunger
for furs for over 100 years when he met them.  The whalers who were the
first to make actual contact with them only hastened the process by
trading groceries in return for virtually all of the caribo to be found
on the costal plains, leading to periods of near famine for some.

More recently "The Georgia Centenarian Study:Nutritional Patterns of
Centenarians" (The International Journal of Aging & Human Development
Vol. 34(1) (1992) 57-76) noted in its findings that 100 year olds do not
shun saturated animal fats - much to the surprise of the researchers.
