The USDA What's in the Foods You Eat is a tool allows you to easily search the FNDDS. This search tool is available for each FNDDS version. The online version of the search tool corresponds to the most recently released version of the FNDDS. The current and previous versions of the search tool can be downloaded from the FSRG website.
In addition to accessing information about individual foods, this search tool can be useful when grouping foods. Specifically, the search tool can be used to see descriptions of specific foods, to get an idea of how many food codes are available for a prospective group, or to scroll through all the foods in a defined range of numeric food codes.
