Fluoride intake of infants mainly fed on formulas depends on the fluoride content of water used to reconstitute formula. Sohn et al. 2009 Fluoride intake in the US children based on their fluid consumption pattern was determined based on National Health and Nutrition Survey (NHANES III). A 24-hour recall diet survey was used to estimate fluid intakes of children aged 1-10 years. Fluoride intake from fluids was based on several assumptions as NHANES III had no information about individual sources. The amount of F ingested by children at the 75th and 90th percentile or higher F intake from fluids was 0.05 and 0.07mg F/kg/day or more which was consistent across all ages. Fluoride ingested by African-American children was significantly higher than that by White children. Socio-demographic factors might have an effect on fluoride ingestion which needs to be further studied since fluoride intake was based on assumptions and was under-estimated.
