We assessed nutrient intake status of 1st and 2nd y Midn, (n=173, male=112 , female=61) prior to initiating a 2-y supplement trial. Intake estimates focused on nutrients crucial to late bone growth that are important to maximize peak bone mass and reduce fracture risk. After instruction based on food models, Midn recorded their food intake for 3 consecutive days. Nutrient intakes were determined using FoodProcessorTM and expressed in actual amounts and as a percentage of the DRI. We used the following DRIs in the order of priority: EAR, AI and 1989 RDA or mid-range ESADDI. Intakes were also compared to the usual median intakes of comparable groups (17-20 y, male=679, female=726) from the 1988-94 NHANES III (NH3). Median daily Midn and NH3 intakes in actual amounts and the Midn intakes as percent of the DRI are shown. Median intake of most key bone-building nutrients exceeded those of the Midn's civilian counterparts. For male Midn, median intakes of most nutrients greatly exceeded the DRI. Female Midn also met or exceeded the DRI for many nutrients, but Ca and Zn intakes were only about 80% of the DRI. K intakes of both male and female Midn failed to meet the DRI.
