Sex Differences In Nutrient Gaps In Active Adults, Christine M. Florez, Christian Rodriguez, Philip Sapp, Jeremy Townsend, Grant M. Tinsley
International Journal of Exercise Science: Conference Proceedings
In the United States, the estimated average requirement (EAR) for a nutrient indicates the average daily intake level estimated to meet the requirement of 50% of healthy individuals. As defined by the United States Department of Agriculture, a “nutrient gap” is evaluated by comparing dietary intakes with EAR values of specific nutrients. Nutrient intake <100% of the EAR indicates a nutrient gap. While nutrient gaps have been characterized in the general population, these gaps are less clearly established in active adults. PURPOSE: To evaluate the presence of nutrient gaps within an active, healthy population and to determine if there are sex differences in nutrient gaps. METHODS: The dietary intakes of healthy, active males (n=380 records) and females (n=301 records) were collected using the National Institutes …
