, and Estimated Average Requirements (EARs) are a more complete set of reference values.

The RDAs are not intended to be used for planning diets for groups or assessing the nutrient intakes of free-living groups (Beaton, 1994~. Rather, the RDAs are intencleci to ensure the acloquacy of nutrient intake.

The likelihood increases the further the intake falls below the RDA. For a requirement that is normally clistributeci, when the usual intake is less than 2 stanciarci deviations below the Estimated Average Requirement (EAR)

The evaluation of true status requires clinical, biochemical, and anthropometric data. If an individual's usual nutrient intake remains below the UL, it is unlikely that there would be an increased risk of adverse effects from excessive intake.

dietary folate equivalent = 1 fig food folate = 0.7 fig of folate added to food or as a supplement consumed with food = 0.5 fig of folate taken as a supplement on an empty stomach.

From page 428... ...
Examples of estimating the prevalence of inacloquate intake appear in Figures 13-3 and 13-4, which use adjusted data from the Third National Health and Nutrition Examination Survey. A large percentage of adults reportedly have a total folate intake less than the EAR (Figure 13-3)
|
From page 429... ...
Overestimates of the prevalence of inacloquate intakes could result from the underreporting of food intake; underestimates of the prevalence of inacloquate intake are also possible. (See Chapter 2 for a discussion of many of the potential sources of error in self-reporteci dietary data.)
|
From page 430... ...
A group mean intake that would be associated with a low prevalence of inadequate intakes can be based on the EAR and the variance of intake. This can be done by using the same principles that were used in the estimation of the prevalence of inacloquate nutrient intakes above (Figure 13-~.

Reported intakes of vitamin BE (diet plus supplements) are well above the Estimated Average Requirement (EAR)

It is anticipated that methods of using the EAR for assessment and planning will be aciciresseci in future reports. OTHER USES OF DIETARY REFERENCE INTAKES For many years, the Recommencleci Dietary Allowances in the United States and the Canaclian Recommencleci Nutrient Intakes have been used by many national and federal agencies for a variety of purposes.

of cooked cereal or rice provides 60 fig of added folate. Moderately fortified ready-to-eat cereals provide approximately 25 percent of the ciaily value per serving according to the product label, which is currently equivalent to 100 fig of acicleci folate (25 percent of 400 Age.

This allows the computation of DFEs for the assessment of intake and for cliet planning, the computation of acicleci folate intake for comparison with the Tolerable Upper Intake Level (UL) , and analysis of the relative contributions of the two forms to total intake.

could readily do so by consuming fortified cereal grains. They could also increase intake of foocis that are naturally high in folate, such as orange juice and cooked cirieci peas and beans, eat more foocis that are good sources of folate, and eat fewer foocis that contain none (such as soft drinks and most cancly)
