2012 Annual Report
1a.Objectives (from AD-416):
MyPyramid Equivalents Database (MPED)is updated with each release of national dietary data to provide the analytical basis to evaluate diets based on the food group recommendations of the Dietary Guidelines for Americans. With the recent replacement of the MyPyramid, the MPED is now named USDA Food Patterns Equivalents Database (USDA, FPED). While the USDA/ARS Food Surveys Research Group has initiated a new process to allow updates to be released at the same time as the release of dietary intake data, resources are needed to support the release of database updates to correspond with prior dietary intake data releases to identify trends over time. The objectives for supporting the retooling of the USDA, FPED are:.
1)to provide USDA, FPED updates for past WWEIA, NHANES cycles in a timely manner;.
2)to reflect changes introduced in USDA Food Group assignments as a result of the new recommendations contained in the 2010 Dietary Guidelines for Americans; and.
3)to provide timely information for the 2015 Dietary Guidelines for Americans Advisory Committee. The Cooperator has the expertise to provide scientific consultation and will assist with provision of partial resources to accomplish these objectives.
1b.Approach (from AD-416):
ARS is currently retooling the USDA, FPED methodology. ARS will review all food codes (7,000+) in the Food and Nutrient Database for Dietary Studies (FNDDS) for the respective past surveys to determine the appropriate amounts of each of the 30+ food groups present in each FNDDS food code. ARS will meet with Cooperator to ensure that the food group assignments are consistent with the current dietary guidelines; and the Cooperator will provide scientific consultation and partial resources for the 2005-2006 and 2009-2010 FPED to ARS.
This agreement is to provide scientific consultation and partial resources from the Center for Nutrition Policy and Promotion (CNPP) for the retooling and development of the 2005-2006 and 2009-2010 Food Patterns Equivalents Database (FPED).
The Food Surveys Research Group (FSRG) has responsibility for the development of the FPED to correspond with specific data releases of national survey dietary data. The FPED, used to evaluate diets based on the food guidance recommendations of the Dietary Guidelines for Americans, provides delineation of 7,000 foods from national dietary survey data into 32 specifically defined components and their equivalent amounts as prescribed in the USDA Food Guidance System. FPED development is being retooled in order to provide the FPED for each two-year release of What We Eat In America, National Health and Nutrition Examination Survey (WWEIA, NHANES) at the time of data release or shortly thereafter. Redesign of the development process is focused on not only timeliness but also assurance of translation of foods to Dietary Guidelines 2010 policies. Quarterly meetings were held in 2011 and 2012 with immediate users of FPED that included scientists from CNPP as well as the National Cancer Institute to provide review and input into the strategic changes for retooling and redesign of FPED, and scientific consultation to assure that food component delineations were being applied as prescribed in the USDA Food Patterns and in concert with the 2010 Dietary Guidelines for Americans.
The redesign process is near completion. As part of that process, the redesign of developing the FPED was applied to WWEIA, NHANES 2003-2004. The redesigned FPED 2003-2004 was compared to the previous MyPyramid Equivalents Database (MPED) 2003-2004, and the results were in agreement. The new redesign process has been applied to WWEIA, NHANES 2007-2008 data. Final quality control checks and reviews of the data are underway. Peer review and release of FPED 2007-2008 are on schedule to be accomplished the first half of 2013. The FPEDs for WWEIA, NHANES survey data cycles 2005-2006 and 2009-2010 are planned for peer review later in 2013.
