Adequate intake (ai): average daily nutrient intake by healthy people when there is not enough research to determine an rda. Tolerable upper intake level (ul): highest amount of nutrient that can be consumed without the risk of adverse health effects. Acceptable macronutrient distribution range (amdr): range of intakes for carbohydrates, fat, and protein that is associated with reduced risk of chronic disease and that provides adequate levels of essential nutrients.
