I know a bit about Inuit and their diet - I've read "My Life with the Eskimo" by Vilhjalmur Stefansson

Stefansson and another explorer, Andersson, participated in an experiment where they did not eat anything but meat for a year - and remained in excellent health

But I haven't heard about the 'rotten fish' and specific nutrients that can be obtained from it ...
