The aims of the present study were to evaluate the fluoride (F) concentrations in whole, defatted and chocolate milks commercially available in Brazil and to estimate the daily F intake from these sources.
F concentrations were determined for 23 brands of milks, after HMDS-facilitated diffusion, using a F ion-specific electrode. Possible F ingestion per kg body weight was estimated, based on suggested volumes of formula consumption, for infants aging 1 to 12 months.
F concentrations ranged from 0.02 to 1.6 microg/mL F for all brands analyzed. Whole and defatted milks had the lowest F concentrations, ranging from 0.02 to 0.07 microg/mL. With respect to chocolate milks, three brands had F concentrations above 0.5 microg/mL. Some brands of chocolate milks exceeded the dose regarded as the threshold level for the development of dental fluorosis, without taking into account other sources of fluoride intake.
The high fluoride concentrations found in some brands of chocolate milks in the present study indicate that many products may be important contributors to the total fluoride intake, reinforcing the need of assaying fluoride content of foods and beverages consumed by small children.
本研究旨在评估巴西市售全脂、脱脂和巧克力牛奶中的氟（F）浓度，并估算这些来源的每日氟摄入量。
使用氟离子特异性电极，在六甲基二硅氮烷促进扩散后，测定了23个品牌牛奶的氟浓度。根据1至12个月婴儿建议的配方奶摄入量，估算了每千克体重可能摄入的氟量。
所有分析品牌的氟浓度范围为0.02至1.6微克/毫升F。全脂和脱脂牛奶的氟浓度最低，范围为0.02至0.07微克/毫升。对于巧克力牛奶，三个品牌的氟浓度高于0.5微克/毫升。一些品牌的巧克力牛奶超过了被视为氟斑牙发展阈值水平的剂量，未考虑其他氟摄入来源。
本研究中在一些品牌巧克力牛奶中发现的高氟浓度表明，许多产品可能是总氟摄入量的重要贡献者，这进一步强调了检测幼儿食用的食品和饮料中氟含量的必要性。
