Infant Recommendations
For most of the micronutrients included in this new report, AIs rather than RDAs are being proposed for infants to age 1 year. EARs and RDAs, however, are proposed for iron and zinc for infants 7 to 12 months of age because the level of iron and zinc in human milk does not meet the needs of older infants and because factorial data are available to estimate the average requirement and from that derive an RDA.
Adequate for What?
A critical point in reviewing the recommendations for intake is to note the specific
Uses of the DRIs
The four primary uses of DRIs are for assessing intakes of individuals and of population groups and in planning diets for individuals and for groups (Table 7). Another DRI report released in 2000 provides suggested approaches for using specific DRIs in dietary assessment (8). It focuses on the use of the EAR in estimating the prevalence of inadequacy and the extent to which an AI can be used given the absence of an EAR, and it provides the statistical basis for these applications. A future
What’s on the Horizon
As indicated earlier, four reports have been released on DRIs, thus completing the initial review of vitamins and almost all elements (a review of electrolytes—sodium, potassium chloride, etc—and water is still to be initiated). Currently, a panel of experts is reviewing protein, amino acids, fats and fatty acids, carbohydrates and fiber, and energy expenditure using the DRI framework, with the report expected by the end of this year. In addition to electrolytes and water, two additional panels
