Abstract

In order to estimate the fluoride ion (F) content of edible salt and the F intake from edible salt consumption in Iran, the F content was measured in 37 brands of edible salt consumed in Iran. The F analysis was made by the standard SPADNS method using a Spectrophotometer DR/5000s (HACH Company, USA). The mean F level of the edible salt was 0.0424±0.012 mg F/g of salt, with a range of 0.020–0.066 mg F/g salt. Based on an estimated mean salt intake in Iran of 9.9±2.9 g/day/person, the mean daily F intake from edible salt was calculated to be 0.420 mg F/day, range 0.212–0.696 mg F/day. After considering the daily salt intake and the levels of F in the drinking water in three provinces in Iran, Gilan, Mazandaran, and Ilam, the total daily intake of F from edible salt and drinking water for adults in these provinces was found to have a range of 0.96–1.21 mg F/day. © 2016.
