Why is there a focus on infant formula as a source of fluoride?
Infant formula manufacturers take steps to assure that infant formula contains low fluoride levels-the products themselves are not the issue. Although formula itself has low amounts of fluoride, when infant formula concentrate is mixed with fluoridated water and used as the primary source of nutrition, it may introduce fluoride at levels above the amount recommended to minimize the risk for fluorosis. Infants consume little other than breast milk or formula during the first four to six months of life, and continue to have a high intake of liquids during the entire first year. Therefore, proportional to body weight, fluoride intake from liquids is generally higher for younger or smaller children than for older children, adolescents, or adults. Mixing concentrate with fluoridated tap water on an occasional basis is unlikely to be of much risk. However, when used consistently as the primary source of nutrition over longer periods of the first year, a child may receive enough fluoride to i
