Abstract

OBJECTIVE:

We evaluated the effect of tamarind (Tamarindus indicus) on ingestion and whether it provides additional beneficial effects on mobilization of fluoride from the bone after children are provided defluoridated water.

METHODS:

A randomized, diet control study was conducted in 30 subjects from a fluoride endemic area after significantly decreasing urinary fluoride excretion by supplying defluoridated water for 2 wk. Subjects were then assigned to one of two groups, with 15 in each group. One group was supplemented with tamarind (experimental group) for 3 wk and the other (control) group was given only defluoridated water for the same period.

RESULTS:

The mean changes in urinary components after tamarind ingestion (volume, pH, fluoride calcium, copper, and magnesium) in the control and experimental groups were compared. There was a significant increase (P < 0.01) in fluoride excretion and urinary pH and a significant decrease in urinary calcium (P < 0.01) and copper (P < 0.05) excretion in the experimental group as compared with the control group. There was no change in urinary volume between groups.

CONCLUSIONS:

Tamarind intake appears to have an additional beneficial effect on the mobilization of deposited fluoride from bone, by enhancing urinary excretion of fluoride.
