Linking USDA Nutrition Databases to IRI Household-Based and Store-Based Scanner Data

by Andrea Carlson, Elina T. Page, Thea Palmer Zimmerman, Carina E. Tornow, and Sigurd Hermansen

To measure the overall healthfulness of Americans' food-at-home (FAH) purchases, USDA researchers created a purchase-to-plate “crosswalk”—linking data between USDA data and household and retail scanner data. Substantial improvements in the healthfulness of Americans' FAH purchases would be needed to comply with Federal dietary guidance.
