EARs have not been established for vitamin K, pantothenic acid, biotin, choline, chromium, fluoride, manganese, or other nutrients not yet evaluated via the DRI process. a A s r e ti nol ac vy qu l( R E).

Tables 5.4 to 5.9 show the average energy requirements of populations with various levels of habitual physical activity and various mean body weights. Apart from some data on excretion of zinc in the urine (Alexander et al., 1974; Cheek et al., 1968; Ziegler et al., 1978), direct measurements of endogenous zinc excretion are not available for older infants, children, or adolescents. For each nutrient, an Estimated Average Requirement was set from which an RDI could be derived.

Other articles where Estimated Average Requirement is discussed: human nutrition: Dietary Reference Intakes: The Estimated Average Requirement (EAR) is the intake level for a nutrient at which the needs of 50 percent of the population will be met. Estimated Energy Requirement (EER) defines the energy you need to maintain this balance. The Estimated Average Requirement for zinc is determined by dividing the physiological requirement by the fractional zinc absorption. (2) RDA = Recommended Dietary Allowance RDA Calculator. The Estimated Average Requirement is the average daily nutrient intake level estimated to meet the requirement of half the healthy individuals in a particular life stage and gender group. EARs are used as the basis for the Recommended Daily Allowance (RDA). These estimates are based on the Estimated Energy Requirements (EER) equations, using reference heights (average) and reference weights (healthy) for each age-sex group. Estimated average requirement (EAR) is the amount of a nutrient that is estimated to meet the requirement of half of all healthy people in a particular life stage and gender group. If one person of 25 years has a certain EER, it is not mandatory that another person of the same age would have the same EER. NOTE: An Estimated Average Requirement (EAR) is the average daily nutrient intake level estimated to meet the requirements of half of the healthy individuals in a group. Show More. Redefining What’s Healthy (You Knew It All Along!) Because the needs of the other half of the population will not be met by this amount, the EAR is increased… Certain factors play roles in deciding the EER value. Estimated amounts of calories needed to maintain calorie balance for various age and sex groups at three different levels of physical activity are provided in Table A2-1.

4 Using the Estimated Average Requirement for Nutrient Assessment of Groups: 73-105: 5 Using the Adequate Intake for Nutrient Assessment of Groups: 106-112 : 6 Using the Tolerable Upper Intake Level for Nutrient Assessment of Groups: 113-126: 7 Specific Applications: Assessing Nutrient Intakes of Groups Using the Dietary Reference Intakes: 127-144: IV. Requirements for groups with other weights and/or mean PAL can be calculated easily, as in the following example for men 20 to 25 years of age with an average weight of 68 kg and an estimated PAL of 1.80: The important thing is that this energy requirement is not the same for all individuals.

(Note that the US:Canadian terminology is 'Recommended Dietary Allowance', or 'RDA').Whilst the various NRVs are expressed on a per day basis, they should apply to intakes assessed over a period of about 3 to 4 days.
