Gontran de Poncins describes the meat eating habits of the Eskimo but doesn't fully try out their diet
EvolutionistX finds from Kabloona:
I do not know what the hour was, but I who had dozed off woke up. Under my eye were the three Eskimos, three silhouettes lit up from behind by the uncertain glow of a candle that threw on the walls of the igloo a mural of fantastically magnified shadows. All three men were down on the floor in the same posture… They were eating, and whether it was that the smell of the seal had been irresistible, or that the idea of the hunt had stimulated their appetites, they had embarked upon a feast. Each had a huge chunk of meat in his hands and mouth, and by the soundless flitting of their arms made immeasurably long in the shadows on the wall, I could see that even before one piece had been wholly gobbled their hands were fumbling in the basin for the next quarter. The smell in the igloo was of seal and of savages hot and gulping. …
I have seen astonishing things, in remote places and not merely in circuses. In the New Hebrides, for example, I have unpacked my own meat in a circle of cannibals and have seen in their eyes a gleam that was perhaps more intense than comforting. Here, in this igloo, all that I had seen before was now surpassed. There were three men, and there must have been fifty pounds of meat. The three men attacked that meat with the rumbling and growling of animals warning their kind away from their private prey. They ground their teeth and their jaws cracked as they ate, and they belched… The walls of the igloo were horrid with the ruddy dripping of bloody spittle and still they ate on, and still they put out simian arms and turned over with indescribable hands morsels in the beginning disdained and now become dainties greedily swallowed. And till, like beats, they picked up chunks and flung them almost instantly down again in order to put their teeth into other and perhaps more succulent bits. They had long since stopped cutting the meat with their circular knives: their teeth sufficed, and the very bones of the seal cracked and splintered in their faces. What those teeth could do, I already knew. When the cover of a gasoline drum could not be pried off with the fingers, an Eskimo would take it between his teeth and it would come easily away. When a strap made of seal skin freezes hard–and I know nothing tougher than seal skin–an Eskimo will put it in his mouth and chew it soft again. And those teeth were hardly to be called teeth. Worn down to the gums, they were sunken and unbreakable stumps of bone. If I were to fight with an Eskimo, my greatest fear would be lest he crack my skull with his teeth.
But on this evening their hands were even more fantastic than their teeth. … Their capacity of itself was fascinating to observe, and it was clear that like animals they were capable of absorbing amazing quantities of food, quite ready to take their chances with hunger a few days later.
The traditional Eskimo diet contains little to no vegetable matter, because very few plants grow up near the North Pole, especially in winter. It consists primarily of fish, seal, polar bear, foxes, and other meats, but by calorie, it is mostly fat. (This is because you can’t actually survive on a majority-protein diet.)
To run through the dietary science quickly, de Poncins has throughout the book been generally eating white-man’s food, which includes things like bread and beans. This is not to say that he disdained fish and seals–he does not make much mention of whether he ate those, but he does talk about bread, potatoes, beans, etc.
