What is the USDA Food and Nutrient Database for Dietary Studies (FNDDS)?
The FNDDS is a database for processing and analyzing nationwide food consumption surveys and other dietary studies. The database includes descriptions of foods, their nutrient values, and weights for typical portion sizes. • How is FNDDS different from the Standard Reference (the USDA National Nutrient Database for Standard Reference)? • Purpose – The USDA National Nutrient Database for Standard Reference (SR) and FNDDS are designed for different purposes. SR is designed for the collection and dissemination of food composition data. FNDDS is designed for the coding and analysis of food consumption data. • Mixtures – The FNDDS data are for foods as consumed, and many of the foods in FNDDS are mixtures that are not available in the SR. SR is the source of the nutrient values for foods in FNDDS, including mixed foods whose nutrient values are calculated using SR items as ingredients. • Portion sizes – FNDDS portion weights are for the types of portion sizes that survey respondents report.
