The above is, of course, biased nonsense from Stefansson. He was trying at the time to promote his all-meat-and-dairy diet and realised that if he used the only example he could think of, namely the Inuit, he would thereby be inadvertently suggesting that a raw-meat diet was healthy - he realised that, given millenia of social conditioning re raw-meat-phobias,people would be much less likely to adopt his diet if they thought that raw meat was part of the diet, so he lied when he claimed that the Inuit didn't eat much of their meats raw. Other people who visited the Eskimoes, such as Weston-Price and other anthropologists, all noted a high intake of raw meats in the Inuit, thus debunking Stefansson's claims.
(Stefansson, by the way, was notorious for his promotion of the "Blond Eskimo" theory, which prompted a number of scientists to accuse him of outright fraud, due to the dodgy evidence presented by him).
As for frozen meats, the Inuit are known to have loved eating frozen "high"-fish - it was their favourite dish, apparently.
