Nutrient Information Sources

Food and nutrient composition information available from the USDA National Nutrient Database for Standard Reference (SR) is the primary source of information relied on in assigning nutrient values to foods in the NCC Food and Nutrient Database. Because values for some nutrients and food components are not available from USDA and information is lacking for many brand name food products, additional resources are utilized.

 

These resources include values from other food and nutrient databases and articles in scientific journals containing values for food products obtained using appropriate analytic methodologies. For more information view Appendix 22 (PDF of the NDSR User Manual.
