The demand for information on issues vital to the well-being of Americans is expanding at a rapid rate, and this has been particularly true in the areas of diet and nutrition. The U.S. Department of Health and Human Services (DHHS) and the U.S. Department of Agriculture (USDA) have been collaborating to find ways to efficiently meet this demand. The National Nutrition Monitoring and Related Research Act of 1990 contains the goals for this collaboration. The papers in this publication provide a review of current data collection activities, plans for the immediate future and, perhaps most important, recommendations for research to meet emerging needs.

The centerpiece of the collaboration has been the integration of DHHS’ National Health and Nutrition Examination Survey (NHANES) and USDA’s Continuing Survey of Food Intake by Individuals (CSFII). Both agencies will continue their cooperation on methods and analysis, with NHANES serving as the data collection mechanism for the joint activities. NHANES is designed to assess the health and nutritional status of the U.S. population. Its design is unique in that it obtains objective measures on a wide range of health and nutritional characteristics that supplement information obtained from personal interview; using the NHANES as the data collection mechanism allows nutritional data to be directly related to health status. Aspects of the CSFII that have been integrated into the NHANES are the use of a new USDA computerized dietary recall data collection system, the processing of dietary recall data through the USDA SurveyNet program and the expansion of a 2nd d 24-h recall to all sample persons to obtain more representative data on an individual’s usual dietary intake. The dietary component and the data resulting from this collaborative effort will be called What We Eat in America. Although What We Eat in America public use files will be released only every 2 y (as is the case with all NHANES components), tabular data will be released yearly.

The USDA and DHHS believe that bringing together the complementary expertise of both agencies in a combined, continuous effort will result in a better data product. It is important that this monitoring effort be viewed as a critical research tool. It is also important that this national monitoring program be buttressed by research sufficient to enable the program to keep pace with changing foods, diet and eating behaviors and with our evolving survey mechanisms.

With guidance from the several communities that need diet and nutrition information, we are confident that our joint efforts can meet the nation’s needs.
