The United States Department of Agriculture (USDA) Food Code Selector simplifies the process of extracting consumption information from What We Eat in America (WWEIA), the dietary component of the National Health and Nutrition Examination Surveys (NHANES). This tool allows filtering of NHANES data via direct selection from 8,000+ food codes using a streamlined user-friendly interface. This Microsoft Excel-based tool decreases dependence on 3rd party software and allows for transparency and accessibility with the tool's traceable decision logic.
This peer-reviewed tool enables users to select foods from NHANES food categories or a keyword search. Users get a quick estimate of annual servings and serving size. Optionally, users can export a list of selected food codes with corresponding estimates of consumption information or a list of codes to import into R or SAS for further analysis. Files are available for individual NHANES cycles (1999-2000 through 2013-14) or for cycles combined. The combined file provides a snapshot of estimated annual servings from the 1999-2013 NHANES cycles for selected foods.
