I recently read Cancer, Disease of Civilization by Vilhjalmur Stefansson (thanks Peter). It really opened my eyes. Stefansson was an anthropologist and arctic explorer who participated in the search for cancer among the Canadian and Alaskan Inuit. Traditionally, most Inuit groups were strictly carnivorous, eating a diet of raw and cooked meat and fish almost exclusively. Their calories came primarily from fat, roughly 80%. They alternated between seasons of low and high physical activity, and typically enjoyed an abundant food supply.
Field physicians in the arctic noted that the Inuit were a remarkably healthy people. While they suffered from a tragic susceptibility to European communicable diseases, they did not develop the chronic diseases we now view as part of being human: tooth decay, overweight, heart attacks, appendicitis, constipation, diabetes and cancer. When word reached American and European physicians that the Inuit did not develop cancer, a number of them decided to mount an active search for it. This search began in the 1850s and tapered off in the 1920s, as traditionally-living Inuit became difficult to find.
