Data from the Ten-State Nutritional Survey, the first Health and Nutrition Examination Survey (HANES), and the Nationwide Food Consumption Survey (NFCS) provide data on changes in American's food habits. Both HANES and NFCS used probability samples representative of the noninstitutionalized population of 48 states, while the Ten-State Survey used random sampling of high nutritional risk groups in the lowest income quartile. Data reliability from 24-hour recall seem adequate for aggregate analysis; data validity of HANES and NFCS have been established by comparisons with other data from public and private sources. Results indicate total food consumption quantity for most, but not all, food groups has decreased. Specific changes in dietary quality include increases in consumption of nonsugary beverages, eggs, nuts, grains, vegetables, fruits, some meats, poultry, and fish and shellfish. Decreases identified include sugary foods, dairy products, and red meat. (cj)
