406 (1) Intakes are reported as mean [+ or -] standard deviation (2) Estimated Average Requirements
do not get the Estimated Average Requirement
of essential micronutrients, including vitamins A, D, E and K, magnesium, calcium and potassium from their diet.
Dickinson and McKay found that reliance upon food alone to receive one's nutrients resulted in intake levels below the Estimated Average Requirement
for many nutrients.
For children aged 7 to 10, the estimated average requirement
of energy is 1970 kilocalories (kcal) a day for boys and 1740 kcal for girls.
The cut-off point of < 70% RDI corresponds approximately with the estimated average requirement
that is now being recommended as one method for evaluation of adequacy of dietary intake of groups (6,7).
The Impact of Using an Estimated Average Requirement (EAR)
Now that the FNB has spent a decade establishing new RDAs for many nutrients, carefully evaluating the data and increasing the recommendations for some nutrients for some age groups, the labeling committee recommends tossing all that aside and basing nutrition policy and labeling instead on the Estimated Average Requirement (EAR).
The report also said that the Estimated Average Requirement
(EAR), weighted by population, should be the basis for DVs whenever possible and if an EAR cannot be identified for a given nutrient, population-weighted Adequate Intakes should serve as the basis for percent DVs.
Nutrient-based standards will also be introduced from September 2008, based on estimated average requirements
of energy, protein, carbohydrate, fibre and other nutrients.
The main alphabetical text is followed by tables giving units of measure, estimated average requirements
for energy, labelling reference values for vitamins and minerals, desirable ranges of heights and weights, intake statistics, food additives, vitamins and fatty acids found in foods.
They also learned the meanings of key terms such as: Estimated Average Requirements
(EAR); Recommended Dietary Allowance (RDA); Adequate Intake (AI); Daily Value (DV); and Tolerable Upper Intake Level (UL)--making this DSC lunch briefing an opportunity for staffers to learn valuable information for their personal use and to help them better understand issues related to policymaking.
Department of Health guidelines give the estimated average requirements
as 1,940 calories a day for women, 2,550 for men.
