Fruit juices and nectars are important fluoride dietary sources, especially in children and adolescents, due to the high consumption. This anion is an hormetine, low exposures are beneficial but high intakes may pose health risks. Therefore, the European Food Safety Authority (EFSA) has established a Tolerable Upper Intake Level (UL). The objective of this study was to determine the fluoride content in 90 samples of juices and nectars representative of the market and to estimate and evaluate the dietary exposure to fluoride, considering variables such as flavor, type of product, origin and type of production. Fluoride determination by potentiometry using an ion-selective electrode showed that juices contain lower levels of fluoride (0,19 mg/L) compared to juices from concentrate (0,43 mg/L) and nectars (0,36 mg/L). Also, organic beverages are richer in this hormetine. In all three consumption scenarios (200, 400 and 600 mL/day) the Estimated Daily Intakes (EDI) of fluoride are highest for juices from concentrate followed by nectars and juices. The consumption of 200 ml/day contributes with 0,086 mg F/L (5,73% of the UL); 0,038 mg F/L (2,53% of the UL) and 0,072 mg F/L (4,8% of the UL) for juices from concentrate, nectars and juices, respectively. In view of these results, in the case of children, it is recommended a moderate the consumption of these beverages and to prioritize juices.
