Data Collection Tools

Food Composition Databases

  • Food Intakes, U.S. Population, 2007-10
    Estimated means and percentiles of the distributions of food intake and the percentage of persons meeting recommendations for a range of sex-age groups in the U.S. population.
  • Food Patterns Equivalents DatabaseExternal Web Site Policy (FPED)
    Database developed by the U.S. Department of Agriculture (USDA) that converts foods and beverages in the Food and Nutrient Database for Dietary Studies to 37 USDA Food Patterns components. FPED was formerly known as the MyPyramid Equivalents Database (MPED).

Diet Analysis Tools

  • Healthy Eating Index
    The HEI is a measure of diet quality, independent of quantity, that can be used to assess compliance with the US Dietary Guidelines for Americans and monitor changes in dietary patterns.
  • Usual Dietary Intakes
    Method to estimate usual dietary intakes of foods and nutrients, including the distribution of usual intake for a population or subpopulation, the effects of individual covariates on consumption, and prediction of individual intake for use in models that assess the relationship between diet and disease or other variables.
