Abstract

Daily Cr, Se, Ag, Cs, Rb, Sb, and Sc intakes of 84 Canadian women aged 30.3±6.1 yr (mean±SD) living in a University community and consuming self-selected diets were determined by analyses of 1-d food composites collected by the subjects. Aliquots of the homogenized food composites were freeze-dried and then analyzed by instrumental neutron activation procedures following irradiation for 72h. In all cases, trace element concentrations in the food composites were non-Gaussian. Median daily intakes were: Cr, 47 μg; Se, 74 μg; Ag, 7.1 μg; Cs, 4.4 μg; Rb, 1.5 mg; Sb 2.0 μg; and Sc, 0.38 μg. Sixty percent and 24% of the subjects received daily Cr and Se intakes, respectively, below the US Food and Nutrition Board safe and adequate range. High Cr density diets were associated with a significantly higher consumption of cheese and dry legumes and nuts (p<0.05). In the high Se density diets, intakes of grain products and breakfast cereals were significantly higher (p<0.05), and intakes of potatoes, table fats, total fat, saturated fat, and oleic acid were significantly lower (p<0.05) compared to the low Se density diets. The low daily Cr intakes evident in this study may be cause for concern in view of the increasing evidence that women may be at greater risk for deficiency of Cr than men because of Cr depletion during pregnancy.
