If you are looking to what the OLD Primitive Eskimos ate and not the internet using Wasilla Hillibillies of today, then I will shine some light on that as well.
Excerpts from: The Straight Dope Website.
Much of what we know about the Eskimo diet comes from the legendary arctic anthropologist and adventurer Vilhjalmur Stefansson, who made several daredevil journeys through the region in the early 20th century. Stefansson noticed the same thing you did, that the traditional Eskimo diet consisted largely of meat and fish, with fruits, vegetables, and other carbohydrates--the usual source of vitamin C
Other aspects of the arctic diet also remain controversial. For example, some say the Eskimos could get vitamin C from blueberries during the summer months. while others say you'd be lucky to find enough berries to cover a bowl of Rice Chex. I say let's not sweat the details of the menu, which varied from region to region anyway. We know Eskimos got enough vitamin C in their traditional diet to survive because obviously they did. Now it's academic--most arctic natives live in villages and get their vitamin C from OJ and Juicy Juice, just like you and I.
Vitamin C can be found in a variety of traditional Eskimo/Inuit staples, including the skin of beluga whales (known as muktuk), which is said to contain as much vitamin C as oranges. Other reported sources include the organ meats of sea mammals as well as the stomach contents of caribou.
