Vilhjalmur Stefansson's Arctic expeditions
From 1905 to 1918 Vilhjalmur Stefansson on various Arctic expeditions spent more than 9 years living entirely on Intuit diets.
He was treated with disbelief. The new science of biochemistry produced many new graduates who thought they has discovered remarkable things about human nutrition, including the importance of vegetables.
In 1928 researchers at Bellevue Medical Center tried to prove that a man can't be healthy living on animal products alone.
Stefansson and a friend, Karsten Andersen, lived, confined to the Bellevue Medical Center, on a 75% fat diet, for a year. (Stefansson's health improved.)
Stefansson thought the experiment was a great success, but the attitude of the researchers, doctors and the public astounded him.
For the researchers, their experiment failed. The result was SILENCE.
