Stefansson only did his Bellevue study for only 1 short year, much of which time he and his fellow testee were not under strict supervision. Therefore, I have my doubts that such a lack of variety is truly sustainable, re really good health, in the long-term. Even the Eskimoes depended on a wide, varied diet, incorporating organ-meats, meats from different species etc.

"Every truth passes through three stages before it is recognised. In the first it is ridiculed, in the second it is opposed, and in the third it is regarded as self-evident."
