ADA offers interim guidance on infant formula and fluoride
"Parents, caregivers and health professionals who are concerned have
some simple and effective ways to reduce fluoride intake from infant
feeding infants breast milk, widely acknowledged as the most complete
form of nutrition for infants;
for infants who get most of their nutrition from formula during the
first 12 months, choosing ready-to-feed formula over formula mixed
with fluoridated water to help ensure that infants do not exceed the
optimal amount of fluoride intake;
if liquid or powdered concentrate infant formulas is the primary
source of nutrition, it should be mixed with water that is fluoride
free (or contains low levels of fluoride) to decrease the risk of
fluorosis, including water that is labeled purified, demineralized,
deionized, distilled or reverse osmosis filtered water to reduce the
risk of fluorosis.
