The trouble with the above observation is that Stefansson himself admitted
that he ate plenty of organ-meats(the marrow of which was raw) in the famous Bellevue experiment(ie liver/kidney/brains/marrow etc.) thus totally invalidating his claim that organ-meats weren't needed on zero-carb. And, judging from info re native-tribes/mediaeval royal courts etc., it was usually customary to share the organ-meats, although elders/royalty got first choice, with servants getting the lowest-quality foods(ie only scraps of some organ-meats).
Even when it's been claimed that Eskimos threw away the organ-meats, it's usually noted in passing that some organ-meats were prized:-
"A delicacy among the North Baffin Inuit is chopped fat and [brains]
mixed with the animal's blood (allupiauoq) in the body cavity before the meat is eaten. Eyeballs
are sucked but not swallowed."

http://www.answers.com/topic/arcticInterestingly, most other sources, such as Weston-Price, generally indicate that the Inuit/Eskimos actually did eat all the parts of the animal:-
"The meat of whales, seals, bearded seals, walrus, narwhals, and polar bears is divided and shared according to cultural rules at the end of the hunt among both Arctic and Subarctic groups. Meat and all the edible parts of killed animals is distributed at feasts after large organized hunts." taken from:-
http://www.answers.com/topic/sea-mammalsOther sources claim that the Eskimos/Inuit also ate the stomach-contents of their prey, in addition to the organ-meats.
It's even been mentioned that Ray Peat wrote an article, somewhere, re the Eskimos having eaten the entire animal:-
"Very nice summary. I tend to agree with your assessment that it is
probably not the omega-3s that are so healthful for the Inuit. Ray Peat
wrote an article that began by discussing a western researcher who ate a
diet of what HE thought was a typical Inuit diet - high levels of whale
blubber. The guy ended up with lots of problems. Peat's conclusion is
that the guy ignored/forgot the fact that the Inuit ate the ENTIRE animal -
not just the flesh meat parts - including organ meats, glands, etc" taken from:-
http://www.newtreatments.org/doc.php/WisdomExperience/52In short, it does seem highly unlikely, that when virtually all other hunter-gatherer tribes/societies are described as prizing organ-meats over muscle-meats, that the Eskimos/Inuit should stand out as the sole exception(other than Vegans like Jainites, I suppose).
Re vitamin C(taken from
http://www.diseaseproof.com/archives/diet-myths-are-the-inuit-healthy.html :- As has been pointed out, vitamin C is so easily lost by cooking, BUT if some of the animal-foods are eaten raw, then there is enough vitamin C available(such as in the case of the Inuits who ate plenty of raw animal food, especially raw organ-meats, and Stefansson who ate some raw marrow(and very lightly-cooked animal food as well):-
"In fact, all it takes to ward off scurvy is a daily dose of 10 milligrams, says Karen Fediuk, a consulting dietitian and former graduate student of Harriet Kuhnlein’s who did her master’s thesis on vitamin C. (That’s far less than the U.S. recommended daily allowance of 75 to 90 milligrams—75 for women, 90 for men.) Native foods easily supply those 10 milligrams of scurvy prevention, especially when organ meats—preferably raw—are on the menu. For a study published with Kuhnlein in 2002, Fediuk compared the vitamin C content of 100-gram (3.55-ounce) samples of foods eaten by Inuit women living in the Canadian Arctic: Raw caribou liver supplied almost 24 milligrams, seal brain close to 15 milligrams, and raw kelp more than 28 milligrams. Still higher levels were found in whale skin and muktuk.
As you might guess from its antiscorbutic role, vitamin C is crucial for the synthesis of connective tissue, including the matrix of skin. “Wherever collagen’s made, you can expect vitamin C,” says Kuhnlein. Thick skinned, chewy, and collagen rich, raw muktuk can serve up an impressive 36 milligrams in a 100-gram piece, according to Fediuk’s analyses. “Weight for weight, it’s as good as orange juice,” she says. Traditional Inuit practices like freezing meat and fish and frequently eating them raw, she notes, conserve vitamin C, which is easily cooked off and lost in food processing."
