ABSTRACT
This study aimed to determine the fluoride and pH levels of beverages likely to be consumed by children
in Malaysia and to estimate daily fluoride intake from consumption of these beverages. A convenience
sampling of 120 ready-to-drink beverages were purchased and categorised into 11 groups (UHT
recombined milk, fresh milk [pasteurised], cultured milk [probiotic], yogurt beverages, fresh fruit
juices, fruit flavoured beverages, soy-based beverages, malt-based beverages, tea, carbonated beverages
and bottled waters). Fluoride concentration was measured using a fluoride ion-selective electrode while
the pH level was measured using a pH meter. The fluoride concentration in the beverages ranged from
0.02±0.00 mg/L to 2.77±0.06 mg/L. Tea was found to have the highest fluoride concentration. The
intake of fluoride from consumption of other types of beverages is below the lowest-observed-adverse-effect level (except tea). The pH of the beverages included in the study ranged from 2.20±0.01 to
7.76±0.00. Carbonated beverages (mean pH: 2.98±0.50) were found to be extremely acidic followed
by fresh fruit juices (mean pH: 3.38±0.34) and fruit flavoured beverages (mean pH: 3.90±0.92).
The correlation between fluoride and pH levels was weak, τ = 0.058 and not statistically significant
(p < 0.35). The majority of the beverages had a low fluoride level and their consumption is unlikely to
cause fluorosis except for tea. Almost half of the beverages had a low pH level with carbonated beverages
being the most acidic.
