Possible genomic criteria for establishing dietary requirements. Estimated Average Requirement (EAR) represents the intake at which the risk of inadequacy is 0.5 (50%) to an individual in a population. Recommended Dietary Allowance (RDA) represents a level of nutrient intake at which the risk of inadequacy is less than 3%. Adequate Intake (AI) is not based on an EAR but is assumed to be near or above the RDA if one could be calculated. The Tolerable Upper Intake Level (UL) represents risk of excess that is set close to 0. NOTE: This figure is available online at www.adajournal.org as part of a PowerPoint presentation.
