The universe for the individual dietary intake phase of the basic survey consisted of members of households in the 48 conterminous states. The sample consisted of members of sample households participating in the household food use phase of the survey.

Results from the 2-year study should be available for use in the planned continuing survey of food intake. FUTURE PLANS A longitudinal survey of individual dietary intake is scheduled to begin in 1985.

From page 24... ...
The dietary change required to meet the RDA or the "Dietary Goals" have been determined for use in exploring the practicality of the guidelines and in determining the direction of educational efforts. Differences in food and nutrient intake by sex and age of individual, household, income, region, ant urbanization of household, season of year, and participation in food stamp and school feeding programs have been explored.

A corporation used survey data to predict demand for a beverage, foods that were eaten with that type of beverage, and eating occasion at which it was selected. _ Example Agricultural economists use data to explain how food production and marketing practices affect household food uses at a given time.

Analyses us ing econometric models are under way at Washington State University and the Un iver s i ty of Missouri. Findings that household size and food expenditures were major determinants of nutrient availability reinforce the food stamp program benefit s tructure.

Survey data for hous ehold food use and food intake o f individual household members were adjusted to comparable bases and compared as background for a methodologic survey of household discard conducted by the University of Arizona. Seasonal availability of foods affects and consumption.

From page 30... ...
Data collected include information on household characteristics, foods used from home food supplies, household income, and participation in food assistance programs. Data were also collected on the intake of specific foods by individuals over a 3-day period.
