Diet and mental health in the Arctic: is diet an important risk factor for mental health in circumpolar peoples?--a review.

Background: The people living in Arctic and Subarctic environments have adapted to cold temperatures, short growing seasons, and low precipitation, but their traditional ways are now changing due to increased contact with Western society. The rapid alteration of circumpolar cultures has led to generational changes in diet from traditional foods to the processed groceries common in modern stores.

Objectives: Develop a link between changing traditional diets and mental health that may have substantial consequences for circumpolar peoples.
