National Health and Nutrition Examination Survey (NHANES) is conducted by Department of Health and Human Services (DHHS) to assess the health and nutritional status of a nationally representative sample of children and adults in the United States. The data are representative of the civilian, non-institutionalized U.S. population. What We Eat in America (WWEIA) and its predecessor the Continuing Survey of Food Intake by Individuals (CSFII) is the dietary intake interview component of the National Health and Nutrition Examination Survey (NHANES). It is conducted as a partnership between the U.S. Department of Agriculture (USDA) and the U.S. Department of Health and Human Services (DHHS). WWEIA consists of two non-consecutive days of 24-hour dietary recall data.
WWEIA-Food Commodity Intake Database (FCID) 2005-10 was developed by U.S. EPA's Office of Pesticide Programs (OPP) to improve the utility of the WWEIA food consumption survey for pesticide dietary exposure assessment. These data are also used by U.S. EPA’s Office of Research and Development to update food consumption rates presented in EPA’s Exposure Factors Handbook. WWEIA-FCID 2005-10 translates food consumption as reported eaten in WWEIA (2005-2010 survey cycles) into consumption of U.S. EPA-defined food commodities. Such food commodity intakes are expressed as grams of food commodity consumed per day or per kg bodyweight per day for over 500 commodities derived from more than 7000 different foods and beverages reported in the two surveys. WWEIA-FCID 2005-10 is intended to complement the CSFII and NHANES/WWEIA databases in that it provides estimates of food consumption expressed as food commodities as opposed to foods per se (i.e., "as eaten") which can in some exposure and other situations be of more utility. The database also includes WWEIA 2005-10 food consumption and demographic data that is available through CDC's National Center for Health Statistics. WWEIA-FCID is an integral component in the Dietary Exposure Evaluation Model (DEEM) used by EPA’s OPP to estimate the dietary exposures to pesticides for the general U.S. population and various demographic subgroups. In general terms, dietary exposures estimated by the DEEM software are derived by multiplying a consumption amount by a pesticide residue in the food commodity.
