They don't really look too healthy. Most people's teeth look horrible. Obviously, they all smoke a lot. Would be a nice illustration to what is happening to native tribes when they start eating "white men" foods. The text states that they eat a lot of animal foods (seafood and caribou), raw, preserved, smoked, salted, and boiled; some vegetation, like berries and sea vegetables; and also supplement their diet with "imported" sugar and white flour products. White flour "porridge" and flat bread fried in walrus oil are now their staples.
