B-1 iii Introduction The USDA National Nutrient Database for Standard Reference (SR) 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. As information is updated, new versions of the database are released. This version, Release 24 (SR24), contains data on 7,906 food items and up to 146 food components. It replaces SR23 issued in September 2010. Updated data have been published electronically on the USDA Nutrient Data Laboratory (NDL) web site since 1992. SR24 includes composition data for all the food groups and nutrients published in the 21 volumes of “Agriculture Handbook 8” (U.S. Department of Agriculture 1976-92), and its four supplements (U.S. Department of Agriculture 1990-93), which superseded the 1963 edition (Watt and Merrill, 1963). SR24 supersedes all previous releases, including the printed versions, in the event of any differences. In July 2001, when NDL converted to a new version of its Nutrient Databank System (NDBS), formats were changed and fields added to improve the descriptive information for food items and the statistical information about the nutrient values.
