USDA Nutrient File
This information is based on and contains data information provided by the USDA National Nutrient Database for Standard Reference (SR)
which is the major source of food composition data in the United States. It provides the foundation for most food composition databases
in the public and private sectors. This version, Release 19 (SR19), contains data on 7,294 food items and up to 140 food components.
Data has been compiled from published and unpublished sources. Published sources include the scientific and technical literature.
Unpublished data include those obtained from the food industry, other government agencies, and research conducted under contracts
initiated by USDA Agricultural Research Service (ARS). These analyses are currently conducted under the National Food and
Nutrient Analysis Program (NFNAP), which began in 1997, in cooperation with the National Heart Lung and Blood Institute,
the National Institutes of Health (Pehrsson et al. 2000). Values in the database may be based on the results of labratory analyses
or calculated by using appropriate algorithms, or recipes, as indicated by the source code in the Nutrient Data file.
Not every food item may contain a complete nutrient profile.
