... Collation, analysis, and reporting of information from these three subsystems should be the responsibility of a lead agency in the federal government. This agency must have adequate personnel and fiscal capability to undertake special purpose analyses of the data bases generated by the above subsystems.

... FOOD INTAKE OF INDIVIDUALS—SUBSYSTEM I It is recommended that this subsystem be established as an ongoing operation, with rapid processing of data and with capability to collate and analyze data on a "moving average" basis. The establishment of data collection, processing, and analysis as an ongoing operation will permit the responsible lead agency to develop and maintain a highly qualified unit operating on a continuous basis.

... The recommended data collection technique is a 24-hour recall by trained interviewers using standardized instruments and food models to help respondents estimate quantity of food consumed and probe for precise information. This recall may be supplemented with a 3-day food record and a food frequency questionnaire to provide additional data concerning frequency of food use.

... Data Base Requirements It will be necessary to charge specific individuals or organizations with the development of requisite data bases for the proposed analysis system from existing information. These data bases will include distribution of nutrient

... It is to be expected that over time the current data bases will improve in quality. The food consumption data base must be maintained in a format that permits recalculation of the intakes and reassessment of risks as other data bases improve or other needs for the data arise.

... The health indicator data base should include information relevant to these acknowledged and possible relationships; however, there are practical limitations on the extent to which health conditions can or should be identified and retained in the data base of this subsystem. Nutritional status is one component of health.

... Comparison of aggregate food disappearance or food purchase data with the composite of food intake data over the time period should provide a basis for predicting relationships between the data bases. With this information, the aggregate data bases may prove to be very useful as an early warning component of the proposed system by detecting changes in foods reaching the consumer.
