A minimum amount of fluoride is necessary for the proper construction of the teeth and bones. However, fluoride increases the synthesis of reactive oxygen species, inflammatory mediators, and impairs the action of enzymes. Beer is the most popular alcoholic beverage in the world. Due to its prevalence and volume of consumption, it should be considered as a potential source of F- and taken into account in designing a balanced diet.
A study analysed beer samples in terms of F- levels. The concentrations of fluoride were examined using ion-selective electrode Thermo Scientific Orion and statistical analysis was based on two-way ANOVA and t test. When compared to imported beers, Polish beers were characterised by the lowest mean F- concentration (0.089 ppm). The highest mean Fconcentrations were recorded in beers from Thailand (0.260 ppm), Italy (0.238 ppm), Mexico (0.210 ppm), and China (0.203 ppm).
The study shows that beer is a significant source of fluoride for humans, which is mainly associated with the quality of the water used in beer production.
