![]() Ī variety of types of foods and their fluoride levels per serving are listed in Table 2. Only trace amounts of fluoride are naturally present in most foods, and most foods not prepared with fluoridated water provide less than 0.05 mg/100 g. The typical fluoride concentration is less than 0.2 mg/L in milk-based infant formula and 0.2 to 0.3 mg/L in soy-based infant formula (not including contributions from tap water used to prepare the formula). Fluoride levels in infant formulas in the United States vary, depending on the type of formula and the fluoride content of the water used to prepare the formula. Fluoride concentrations in cow’s milk are also very low, ranging from 0.007 to 0.086 mg/L. ![]() įluoride concentrations in breast milk are so low that they cannot always be detected when these levels can be measured, they range from less than 0.002 to 0.01 mg/L, even when mothers live in communities with fluoridated water. Fluoride levels can range from 0.3 to 6.5 mg/L (0.07 to 1.5 mg/cup) in brewed tea made with distilled water. ![]() Table 1: Daily Adequate Intakes (AIs) for Fluoride Ageīrewed tea typically contains higher levels of fluoride than most foods, depending on the type of tea and its source, because tea plants take up fluoride from soil. Table 1 lists the current AIs for fluoride for healthy individuals. Therefore, the board established AIs for all ages using estimated intakes shown to maximize reductions in the incidence of dental caries without unwanted side effects, such as dental fluorosis, a chronic condition resulting from the consumption of too much fluoride when teeth are developing. The FNB found the data insufficient to derive EARs for fluoride.
