Because of the popularity of fast foods in the U.S., databases used to assess food and nutrient intakes must be kept up‐to‐date for these foods. Portion weights are an important part of the data, and restaurants may change portions over time. Accordingly, portion data for frequently consumed foods commonly obtained from quick service restaurants (QSR) were evaluated for the USDA Food and Nutrient Database for Dietary Studies (FNDDS) 2.0 prepared for use with What We Eat in America, National Health and Nutrition Examination Survey 2003–2004 (NHANES). Based on frequency of reported use, 479 weights for these foods were reviewed by comparisons to available published industry data, as well as the National Nutrient Database for Standard Reference, release 17, current in 2004. FNDDS weights specific to one QSR brand were directly compared to reference data. FNDDS weights representing composites for use when brands were not specified were compared to weighted averages of values for the top brands, e.g., the weighted averages for portions of pizza were based primarily on market shares for the top four pizza chains. The reviewed items represented 5% of all reported foods and 11% of total energy intake in NHANES 2003–2004. The selection of priority foods and portions, changes resulting from the evaluation, and their contribution to NHANES nutrient intakes will be presented, as well as the effect of new portion weights for pizza.
