Since the Gold Rush toward the end of the 1800's, Alaska has been less isolated and residents have been able to supplement their diet with dried beans, grains, cured meats, and canned foods. Barley proved to do well in the Alaskan climate and became a primary starch. Of all the regions of the United States, it's interesting to note that Alaska is probably the only one that did not include corn as traditional dietary staple.
Also, before the Gold Rush and the introduction of the oven, most food were either eaten raw or it was smoked for preservation. These days, you'll find a lot of braised preparations and slow-simmered stews.
