Location: Food Surveys Research Group2013 Annual Report
1a. Objectives (from AD-416):
The purpose of this agreement is to study and assess how American’s diets meet the recommendations of the Dietary Guidelines for Americans. The study will investigate and define foods in the USDA Food and Nutrient Database for Dietary Studies (FNDDS) by the components in the USDA Food Patterns. The resulting Food Patterns Equivalents Database will provide the analytical basis to evaluate diets based on recommendations of the Dietary Guidelines for Americans. In addition, research support to evaluate the clinical/biochemical aspects of foods/food patterns and their associated bioactive constituents that relate to chronic disease prevention will be addressed.
1b. Approach (from AD-416):
Identification of the amounts of more than 30 components in the USDA Food Patterns will be determined and applied to more than 7,000 foods reported in national dietary food consumption surveys in order to support application of the Dietary Guidelines for Americans. This work will provide the technical and scientific support for development of the USDA Food Patterns Equivalents Databases. The Cooperator will provide expertise in knowledge needed about foods, their ingredients and components, and skills in database development.
3. Progress Report:
This agreement is to provide scientific consultation and support for the investigation and identification of the amounts of 37 Food Pattern components in 7,000 foods and beverages in the USDA Food and Nutrient Database for Dietary Studies for the purpose of development of the USDA Food Patterns Equivalents Database (FPED) with the University of Maryland. 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 and beverages from national dietary survey data into 37 specifically defined Food Pattern components. 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. University of Maryland scientific staff provided review and evaluation of the foods and beverages in FNDDS in relation to the 37 Food Pattern (FP) components, detailing for each item, the amount of each of the components, as appropriate. Extensive scientific review was conducted to assure that the content of the food or beverage item was accurately characterized for each component. Quality control criteria and standards were developed and applied across the database for internal and scientific integrity. Asisstance in the development of documentation reports was also provided. The redesign process is complete. 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 and 2009-2010 data. Release of FPED 2007-2008 and 2009-2010 has been completed. Each release has several products including 1) a Food Patterns Equivalents Ingredient Database of each unique ingredient in FNDDS, 2) a database of the amounts of 37 FP components present per 100 grams of each FNDDS food and beverages, 3) the amount of 37 FP components present in each food and beverage reported and the total for the day by each respondent on day 1 and day 2 of WWEIA, NHANES, 4) four summary table sets on the mean intakes of the 37 FP components by 23 age-gender and socioeconomic subgroups, and 5) a Methodology and User Guide. Development of FPED 2005-2006 and 2011-2012 is underway. Release of FPED 2011-2012 is planned for the summer of 2014, shortly after WWEIA, NHANES 2010-2012 data release. Release of FPED 2005-2006, including the four products described above, is planned for early 2015.
