Rice as a vehicle for dietary fluoride uptake.
The objective of this study was to analyze aspects of the metabolism and bio-availability of fluoride after consumption of a sample of polished white rice containing 5.6 ppm fluoride ion. Up to 400 g of fluoridated rice was consumed by three volunteer adult subjects over specific time periods on two separate occasions. Saliva concentrations were elevated immediately and remained so 90 minutes following ingestion, among other indications. It was concluded that polished rice has the potential to be a useful vehicle for dietary fluoride transport.
