Coordinating Committee on Evaluation of Food Consumption Surveys

Subcommittee on Criteria for Dietary Evaluation

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.

Assessment Using Food Consumption Surveys

Nutrient Adequacy:

In response to a request of the Human Nutrition Information Service of the U.S. Department of Agriculture, a committee was established under the auspices of the Food and Nutrition Board of the National Research Council's Commission on Life Sciences to review the uses of the Nationwide Food Consumption Surveys (NFCS) and make recommendations to facilitate wider application of the resulting survey data. The Committee also reviewed and made recommendations regarding the National Health and Nutrition Examination Survey (NHANES), a project of the National Center for Health Statistics of the Department of Health and Human Services (DHHS). This report, to those responsible for the surveys, contains the Committee's findings and recommendations.
