Just how accurately can adequate nutrient intake be measured? Do food consumption surveys really reflect the national diet? This book includes a brief history of dietary surveys, and an analysis of the basis of dietary evaluation and its relationship to recommended dietary allowances. A discussion of how usual dietary intake may be estimated from survey data, a recommended approach to dietary analysis, and an application of the analysis method is presented. Further, an examination of the impact of technical errors, the results of confidence interval calculations, and a summary of the subcommittee's recommendations conclude the volume.
