THE NATIONAL ACADEMIES
Advisers to the Nation on Science, Engineering, and Medicine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council.

On behalf of the panel, I would like to thank all of the individuals involved in the production of this report. First, I thank my fellow panel members for giving their time and expertise so generously toward the completion of this report. Each of their contributions to the discussion at the workshop and in the drafting of this report is greatly appreciated.
A major activity of this panel was a workshop, held in May 2004. I thank everyone who presented information and shared their ideas for improvements in the food consumption and expenditures data infrastructure. Their willingness to share these ideas in a somewhat informal manner during the workshop was very much appreciated. I appreciate the help of several individuals from the federal government, private firms, and universities who were consulted by staff of the Committee on National Statistics about workshop topics and potential workshop participants: Harry Balzer of the NPD Group; Mary Brandt of the Food and Drug Administration; Gary Crisafulli of ACNielsen; Helen Jensen of Iowa State University; Clifford Johnson of the National Center for Health Statistics, who also provided critical information on current details and future plans for the National Health and Nutrition Examination Survey; Alanna Moshfegh of the Agricultural Research Service of the U.S. Department of Agriculture; and Catherine Woteki of the University of Iowa. The summary of the workshop is Appendix A.
I also thank our sponsor, the Economic Research Service (ERS) of the U.S. Department of Agriculture. ERS staff Elizabeth Kuhn, Nicole
Ballenger (who is now with the University of Wyoming), James Blaylock, Mark Denbaly, and Biing-Hwan Lin aided the development of the workshop and provided information to the panel.
The panel is grateful for the excellent work of the staff of the Committee on National Statistics (CNSTAT) and the National Research Council for developing and organizing the workshop and this report. Michele Ver Ploeg, study director for the panel until October 2004, was chiefly responsible for organizing the workshop and drafting the panel’s report. Earl Pollack, study director for the panel since October 2004, completed the report and shepherded it through the review process with the assistance of Constance Citro, CNSTAT director. Throughout, the panel benefited immensely from Connie’s advice and collaboration. We also thank Jamie Casey, research associate, for drafting the workshop summary and for providing research support, and Tanya Lee, program assistant, for handling all administrative matters for the workshop. Jerusha Nelson Peterman, science and technology policy intern with CNSTAT, gathered background information on many of the datasets discussed in the report and contacted staff at the agencies that produce these data to clarify details. The panel is also grateful to Eugenia Grohman of the reports office of the Division of Behavioral and Social Sciences and Education for her professional editing of the report.
This report has been reviewed in draft form by individuals chosen for their diverse perspectives and technical expertise, in accordance with procedures approved by the Report Review Committee of the National Research Council. The purpose of this independent review is to provide candid and critical comments that will assist the institution in making its published report as sound as possible and to ensure that the report meets institutional standards for objectivity, evidence, and responsiveness to the study charge. The review comments and draft manuscript remain confidential to protect the integrity of the deliberative process.
We thank the following individuals for their review of this report: Jay Bhattacharya, Stanford Medical School, Stanford University; Gladys Block, Public Health Nutrition Program, School of Public Health, University of California, Berkeley; Daniel S. Gaylin, Department of Health Survey, Program, and Policy Research, National Opinion Research Center, Washington, DC; Chris Logan, Education and Family Support, Abt Associates Inc., Cambridge, MA; Valerie Tarasuk, Department of Nutritional Sciences, University of Toronto; Parke E. Wilde, Friedman School of Nutrition
Science and Policy, Tufts University; and James P. Ziliak, Center for Poverty Research and Department of Economics, University of Kentucky.
Although the reviewers listed above have provided many constructive comments and suggestions, they were not asked to endorse the conclusions or recommendations nor did they see the final draft of the report before its release. The review of this report was overseen by Robert Moffitt, Department of Economics, Johns Hopkins University. Appointed by the National Research Council, he was responsible for making certain that an independent examination of this report was carried out in accordance with institutional procedures and that all review comments were carefully considered. Responsibility for the final content of this report rests entirely with the authoring panel and the institution.
