The objective of this study was to estimate the prevalence of inadequate usual nutrient intake among female university students. This was a cross-sectional study in which 119 students at a public university in the State of Sao Paulo, Brazil, completed 3-day estimated food records. These were analyzed for nutrient content, and intake distributions were determined. Nutrient intake distributions were estimated using the National Research Council method. For nutrients for which an Estimated Average Requirement has been established, the Estimated Average Requirement cutpoint method was used to determine the proportion of students with inadequate intake. The students' food records indicated inadequate intakes of folate (99%), zinc (47%), and copper (33%). For approximately 95% of the students in this study, calcium was less than the Adequate Intake. The results showed the need for improvement in dietary choices to minimize the prevalence of inadequate intake of folate, zinc, copper, and calcium in this group.
