Dietary Reference Intake (DRIs) are a set of energy and nutrient intake standards that can be used as references when making dietary recommendations. DRIs include: ## Estimated Average Requirements (EARs) The amount of nutrient that should meet the needs of 50% of healthy people who are in a particular life-stage/sex group. ### Estimated Energy Requirements (EERs) The average daily energy intake that meets the needs of a healthy person maintaining their weight. EER takes into account: - Physical activity level - Height - Weight - Sex - Life stage - Health status ## Recommended Dietary Allowances (RDAs) The standard for recommended daily intake of several nutrients. ## Adequate Intakes (AIs) Recommendations that assume a population's average daily nutrient intakes are adequate because no deficiency diseases are present. ## Tolerable Upper Intake Levels (ULs) The highest average amount of a nutrient that is unlikely to harm most people. ## Acceptable Macronutrient Distribution Range (AMDR)
