Abstract

Breakfast cereals and snacks are foodstuffs highly appreciated by children, and the possibility that they contain substantial amounts of fluoride, associated with their widespread consume, may make them important contributors to the total daily fluoride intake. The aim of this study was to analyze the fluoride content on several breakfast cereals (A) and snacks (B) purchased in Brazil. The analysis were made after HMDS-facilitated diffusion (Taves) using the ion-specific electrode (9609). Mean fluoride concentrations ± SD (range, unit mg F/g) were: A= 0.76 ± 0.60 (0.08-1.86, n=15) and B= 0.32 ± 0.09 (0.22-0.55, n=18). Our results suggest that the total amount of fluoride available in some products may contribute to the total daily fluoride intake. The product labels should provide information on their fluoride content to prevent fluorosis at the age of risk.Cereais matinais e salgadinhos são guloseimas altamente apreciadas pelas crianças, e a possibilidade de conterem quantidades substanciais de flúor, associada ao seu indiscriminado consumo, pode torná-los importantes contribuintes para a ingestão diária total de flúor. O objetivo deste estudo foi analisar o conteúdo de flúor em diversos cereais matinais (A) e salgadinhos (B) adquiridos no Brasil. As análises foram feitas após difusão facilitada por HMDS (Taves), usando o eletrodo íon específico (9609). As concentrações médias de flúor ± SD (amplitude, unidade mg F/g) foram: A= 0,76 ± 0,60 (0,08-1,86, n=15) e B= 0,32 ± 0,09 (0,22-0,55, n=18). Nossos resultados sugerem que a quantidade de flúor presente em alguns produtos pode contribuir com a ingestão diária total de flúor. Os rótulos dos produtos deveriam informar seu conteúdo de flúor para prevenir fluorose no período de risco.
