摘要: Abstract Approximations of retinol (A), cholecalciferol (D), and α-tocopherol (E) in frequently consumed traditional Arctic food were made applied to dietary analysis within a large-scale effort assess nutrient adequacy Indigenous Peoples the Canadian Arctic. A total 180 independent samples species expected be reasonable sources fat soluble vitamins sampled from wide geographic range. Many values for these are reported first time tissues. Excellent all three nutrients found sea mammal fats (beluga, narwhal, seal, walrus) organ meats (liver both land species). Fish (char, cisco, lake trout, loche, sculpin, whitefish) was especially rich D, with highest levels loche liver (mean 318 μg/100 g). After inserting data into our composition database, estimations inadequacy Dene/Metis, Yukon First Nations Inuit A, E conducted using SIDE software. Results revealed close 100% vitamin but better results Inuit. Only likely adequate D. All groups inadequate E. It is concluded that resources excellent fat-soluble can promoted protect nutrition indigenous populations.
