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 28 (SR28), contains data on 8,789 food items and up to 150 food components. 

You can either view the data on line or download the data files and documentation in several different formats for use on your computer. An online search is also provided so you can look up the nutrient content of 8,789 different foods directly from the home page.
