Dietary reference intakes (DRIs) present evidence-based criteria for an acceptable range of amounts of vitamins and nutrients for each gender and age group. DRIs have four components. The estimated average requirement (EAR) is the recommended amount of a nutrient that appears sufficient to maintain a specific body function for 50% of the population based on age and gen-der. The recommended dietary allowance (RDA) indicates the average needs of 98% of the pop-ulation, not the exact needs of the individual. Adequate intake (AI) is the suggested intake for individuals based on observed or experimentally determined estimates of nutrient intakes and is used when evidence is insufficient to allow the RDA to be set. The tolerable upper intake level (UL) is the highest level that likely poses no risk of adverse health events. It is not a recom-mended level of intake. The food guide pyramid is not a component of the DRIs.
