Fluoride content of prepackaged fruit juices and carbonated soft drinks.

Epidemiological studies have established the beneficial effects of water fluoridation. Present dietary trends, however, indicate that many Australian children may consume more prepackaged fluids than actual tap water. The fluoride concentrations of a selection of carbonated soft drinks and prepackaged fruit juices were investigated. The results indicate that, in an optimal fluoride area such as Sydney, children who consume a consistent and large proportion of their fluids as carbonated soft drinks in cans, fruit juices and fruit drinks may not be receiving the full benefit of the water fluoridation.
