Technical Abstract: Objective: Past fluoride (F) intake research has been hindered by the lack of a database for food and beverage F levels, and standardized approaches to assess dietary and non-dietary F intakes. This presentation presents an overview of the "National Fluoride Database and Intake Assessment Study," a new collaborative effort of the University of Minnesota School of Public Health (MN), the USDA Nutrient Data Lab (NDL), the University of Iowa College Of Dentistry (IA), and Virginia Polytechnic Institute (VPI). Methods/Results: The study will estimate F concentration levels and variability in a national sample of commercial drinking waters, beverages, and foods. Product sampling, purchasing, and review of quality control are by NDL, preparation of sample aliquots by VPI, and fluoride assay by IA. MN will develop a computer-based assessment for F intake in individuals, including dietary and nondietary sources and incorporating the national F database. The assessment methodology will include questionnaires of previous F intake and incorporation of assayed F values for actual water and water-based beverages consumed. The F module will be incorporated into the Minnesota NDS-R software for estimating intake of other nutrients. Conclusions: Results will assist future research concerning F intake by providing national average F levels for many foods and beverages, by standardizing approaches and allowing quantitative estimates of F intake for individuals.
