Food consumption data needs for food and agricultural policy.

Food and agricultural policy strives to provide stable, safe, nutritional, and affordable food supplies with policies on farm income, low-income food security, food safety (including nutritional risk), and nutrition education. For each policy area, comparisons are made between food consumption data needs and information currently collected with four human nutrition monitoring system components administered by the U.S. Department of Agriculture. Identified data gaps become the basis for recommendations for future data needs. Food consumption data are essential to management of programs. However, many food safety and nutritional well-being issues require specific food product consumption data for high risk groups. Sampling procedures are often too aggregate to meet these needs. Food consumed away-from-home is not well measured, yet this market segment now accounts for about half of all consumer food expenditures. Surveys should be designed to provide complementary and additive data. A premium should be placed on standardizing household description variables to enable "splicing" together data from different surveys. Survey continuity across time is essential. Data collection should be planned with funding limitations and respondent burden in mind so that a balance is achieved between survey objectives and the practical constraints of obtaining accurate data.
