2013 Annual Report
Trans fat values for many foods reported in the What We Eat in America survey were reviewed and will be added or updated in the NDL core file of 3,200 foods used in the development of the Food and Nutrient Dataset for Dietary Studies (FNDDS). Some will be assigned an assumed “0”. Sodium values for foods which are major contributors of sodium in the American diet, due to concentration, level of consumption or both (e.g., including Sentinel Foods under Sodium Monitoring collaboration with CDC and FDA and all FNDDS foods), were reviewed and updated as warranted.
USDA’s databases on the flavonoid content of selected foods were expanded to include full profiles for six subclasses (flavanols, flavonols, flavones, flavanones and anthocyanidins plus isoflavones) for all the ~2,900 food items included in FNDDS 4.1 and used in NHANES 2007-08. Analytical values were taken from Release 3.1 of the flavonoid database and Release 2.0 of the isoflavone database. Release 3.0 of the flavonoid database was updated during FY2012 to correct a few values and add some additional food items to create Release 3.1. As part of release 3.1 individual data points used to create the mean values, along with data on the glycosides, analytical method, conversion factors (including converting individual glycosides to the aglycone form, moisture and specific gravity), and location where samples were obtained, were made available. Other values needed for the expanded database were calculated from the analytical values or assigned an assumed “0”. The data will be used in the investigation of the relationship between dietary intakes of flavonoids and health benefits through epidemiological studies.
NFNAP provided complete, accurate, and current data for frequently consumed Key Foods and nutrients of public health significance. NIH support for the NFNAP has enabled NDL to generate current and nationally representative data for many food items and dietary supplements found in the rapidly changing market place. USDA’s food composition data are regarded as the foundation and benchmark for all second-generation databases concerning nutrition monitoring, nutrition research, and food policy in the U.S. Data for both foods and dietary supplements are needed to assess total nutrient intake for the U.S. population. In addition, food composition data for bioactive components are key elements in nutrition research projects which investigate the role of the intake of components in maintaining health status. Data for this project were received in monthly reports, and frequent communication with collaborators has taken place through email, periodic meetings, and conference calls.
