Ch. 3.1

acceptable macronutrient distribution ranges (AMDRs)

macronutrient intake ranges that are nutrtionally adequate & may reduce the risk of diet-related chronic diseases; determine whether your diet has a healthful balance of macronutrients

tolerable upper intake level (upper level or UL)

standard representing the highest average amount of a nutrient that's unlikely to be harmful when consumed daily; risk of a toxicity disorder increases when a person regularly consumes amounts of a nutrient that exceed its UL

recommended dietary allowances (RDAs)

standards for recommending daily intakes of several nutrients; meet the nutrient needs of nearly all healthy individuals (97 to 98%) in certain life stage/sex group; nutrition scientists add a margin of safety amount to EAR that allows individual variations in nutrient needs

estimated average requirement (EAR)

amount of a nutrient that meets the needs of 50% of healthy people in a life stage/sex group; shouldn't use standard to judge whether you daily intake is adequate bc it's only 50%

estimated energy requirement (EER)

average daily energy intake that meets the needs of a healthy person maintaining his or her weight; accounts for person's physical activity level, height, weight, sex, & life stage

adequate intakes (AIs)

dietary recommendations that assume a population's average daily nutrient intakes are adequate bc no deficiency diseases are present; scientists record eating patterns of a group of healthy people & estimate the group's average daily intake of nutrient; your diet is more likely to be nutritionally adequate if your average daily intake for each nutrient meets the nutrient's RDA or AI value

requirement

smallest amount of a nutrient that maintains a defined level of nutritional health; prevents development of a nutrient deficiency; varies by age, sex, health status, physical activity, life cycle stage (pregnancy)

dietary reference intakes (DRIs)

various energy & nutrient intake standards for americans; used by RDs for diets
