Abstract
Objectives: To assess (1) energy and nutrient intake; (2) dietary adequacy; (3) traditional and nontraditional foods consumed; and (4) main foods contributing to energy and selected nutrient intake among Yup’ik women in Western Alaska.
Methods: Up to 3 24-hour dietary recalls were collected to assess the dietary intake. Dietary adequacy was determined by comparing women's daily nutrient intakes to corresponding dietary reference intakes (DRIs).
Results: Mean daily energy intake for the women was 2172 kcal, exceeding the DRI for energy. The majority of women (90–100%) fell below the recommendations for dietary fiber, calcium, and vitamins D and E. More than 50% of women fell below the recommendations for vitamin A, and more than one third were below the DRI for zinc and vitamins C and B6. Juices/pop (including Tang, Kool-Aid, soda/pop, fruit juice, and energy drink), coffee, and traditional fish were the most frequently reported food items. Sweetened beverages and pop were the main contributors to energy, carbohydrate, and sugar intake. Traditional foods provided 34% of protein, 27% of iron, 23% of vitamin A, and 21% of zinc.
Conclusions: Among Yup’ik women, juices/pop were the most frequently consumed foods contributing to the high energy intake. However, traditional food still contributes substantially to certain nutrients. These data contribute to an understanding of dietary adequacy in this population and will aid in the development of a nutritional intervention program.
