Research Project: DEVELOPMENT OF FOOD COMMODITY ECONOMIC DATABASE FOR WHAT WE EAT IN AMERICA, NHANES 2005-2006

Location: Food Surveys

2010 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.


3.Progress Report

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 as Retail Commodities Database has been developed by translating 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 have been produced that convert foods consumed to retail-level commodities using the database for the following national dietary surveys: the Continuing Survey of Food Intakes by Individuals, 1994-1998; National Health and Nutrition Examination Survey, 1999-2000; and What We Eat in America, National Health and Nutrition Examination Survey, 2001-2002. Peer review of the three databases, documentation, and data table sets has been completed. A poster and an oral presentation were made on the development of the databases at two scientific meetings. Work has begun to develop a comparable retail level commodity database for the What We Eat In America, National Health and Nutrition Examination Survey, 2005-2006.

Monitoring activities for this project include joint technical conference calls approximately every 6 months between key Food Surveys Research Group scientists and Economic Research Service economists to review the retail commodity groups for the database.
