2011 Annual Report
1a.Objectives (from AD-416)
The purpose of this agreement is to develop a commodity food database, hereinafter the Food Commodity Economic Database (FCED) for What We Eat In America, NHANES 2005-2006. The FCED, an expansion of the Food and Nutrient Database for Dietary Studies 3.0 developed by FSRG to code and process WWEIA, NHANES 2005-2006 dietary data, is designed to convert foods reported in WWEIA, NHANES 2005-2006 to ERS food commodities.
1b.Approach (from AD-416)
Staff at the Food Surveys Research Group, ARS, will work with a senior economist at the Food Economic Division, ERS, to plan, develop, and document the development of FCED and collaborate with ERS in the preparation of manuscripts on common areas of interest to ARS and ERS.
The 2005-2006 FCED will be applied to 2005-2006 WWEIA, NHANES dietary recall data to estimate the amount of food commodities consumed by Americans. Various USDA reports will be prepared by staff at ERS and ARS. The FCED database will be made publicly available on the Web.
This agreement is to develop a database that allows foods reported in the national dietary intake surveys to be translated into retail commodities in order to report on food consumption by those commodities. A retail commodity is defined as a selected form of a food that is available for purchase in retail stores, supermarkets, or other retail food outlets (e.g., orange with peel, raw boneless beef). The Food Intakes Converted to Retail Commodities Database (FICRCD) has been developed by converting the more than 7,000 unique foods included in the Food and Nutrient Database for Dietary Studies into respective amounts of 65 retail commodities by disaggregating those foods into ingredients, where necessary, assigning foods/ingredients to the retail commodity groups and applying conversion factors as appropriate, and computing amounts of each of the 65 retail commodities present in 100 grams of survey food. The list of 65 retail commodities was jointly determined by scientists at ARS and economists at the Economic Research Service. Three unique databases and related summary data table sets that convert foods consumed to retail-level commodities using the database for the following national dietary surveys were released during FY2011 on the Web: The Continuing Survey of Food Intakes by Individuals, 1994-96 and 1998; National Health and Nutrition Examination Survey, 1999-2000; and What We Eat In America, National Health and Nutrition Examination Survey, 2001-2002. In addition, a Methodology and User Guide for the FICRCD was also developed that describes the process of disaggregations of foods, their assignments to appropriate commodities, and the application of conversion factors to convert foods to respective amounts of commodities. The methodology used for these three surveys is being applied to the development of two comparable retail level commodity databases for the What We Eat In America, National Health and Nutrition Examination Surveys for 2003-2004 and 2005-2006.
This agreement was monitored through periodic emails, telephone calls, and joint meetings with ERS scientists.
