Indigenous Peoples globally are part of the nutrition transition. They may be among the most extreme for the extent of dietary change experienced in the last few decades. In this paper, we report survey data from 44 representative communities from 3 large cultural areas of the Canadian Arctic: the Yukon First Nations, Dene/Métis, and Inuit communities. Dietary change was represented in 2 ways: 1) considering the current proportion of traditional food (TF) in contrast to the precontact period (100% TF); and 2) the amount of TF consumed by older vs. younger generations. Total diet, TF, and BMI data from adults were investigated. On days when TF was consumed, there was significantly less (P < 0.01) fat, carbohydrate, and sugar in the diet, and more protein, vitamin A, vitamin D, vitamin E, riboflavin, vitamin B-6, iron, zinc, copper, magnesium, manganese, phosphorus, potassium, and selenium. Vitamin C and folate, provided mainly by fortified food, and fiber were higher (P < 0.01) on days without TF for Inuit. Only 10-36% of energy was derived from TF; adults > 40 y old consistently consumed more (P < 0.05) TF than those younger. Overall obesity (BMI > or = 30 kg/m(2)) of Arctic adults exceeded all-Canadian rates. Measures to improve nutrient-dense market food (MF) availability and use are called for, as are ways to maintain or increase TF use.
Objectives. The food supply of Inuit living in Nunavut, Canada, is characterized by market food of relatively low nutritional value and nutrient-dense traditional food. The objective of this study is to assess community perceptions about the availability and accessibility of traditional and market foods in Nunavut. Study Design. A qualitative study using focus group methodology. Methods. Focus groups were conducted in 6 communities in Nunavut in 2004 and collected information was analyzed. Results. Barriers to increased traditional food consumption included high costs of hunting and changes in lifestyle and cultural practices. Participants suggested that food security could be gained through increased economic support for local community hunts, freezers and education programs, as well as better access to cheaper and higher quality market food. Conclusions. Interventions to improve the dietary quality of Nunavut residents are discussed. (Int J Circumpolar Health 2006; 65(5):416-431)
Food systems of Canadian Arctic Indigenous Peoples contain many species of traditional animal and plant food, but the extent of use today is limited because purchased food displaces much of the traditional species from the diet. Frequency and 24-h dietary interviews of Arctic adults and children were used to investigate these trends. The most frequently consumed Arctic foods were derived from animals and fish. In adults these foods contributed 6-40% of daily energy of adults. Children ate much less, 0.4-15% of energy, and >40% of their total energy was contributed by "sweet" and "fat" food sources. Nevertheless, for adults and children, even a single portion of local animal or fish food resulted in increased (P < 0.05) levels of energy, protein, vitamin D, vitamin E, riboflavin, vitamin B-6, iron, zinc, copper, magnesium, manganese, phosphorus, and potassium; although children had similar results for these nutrients, they did not reach significance for energy, vitamin D, or manganese. Because market foods are the major source of energy in the Arctic, traditional animal-source foods are extremely important to ensure high dietary quality of both adults and children.
Traditional food resources of indigenous peoples are now recognized as containing a variety of environmental contaminants which reach food species through local or long-range transport avenues. In this chapter we review the published reports of contaminants contained in traditional food in northern North America and Europe as organochlorines, heavy metals, and radionuclides. Usually, multiple contaminants are contained in the same food species. Measurement of dietary exposure to these environmental contaminants is reviewed, as are major issues of risk assessment, evaluation, and management. The dilemma faced by indigenous peoples in weighing the multiple nutritional and socioeconomic benefits of traditional food use against risk of contaminants in culturally important food resources is described.
