"According to the article, in metropolitan areas (such as Los Angeles) where high fluoride is present in tap water, infants are getting too much fluoride regardless if they are bottle-fed or breast-fed."
"MWD's plan to add fluoride to the water it supplies to 18 million customers in most of Los Angeles, Orange, San Diego, and parts of San Bernardino, Riverside and Ventura counties will put 14.5 percent of children under 1 year old, and 12.5 percent of children 1 to 2 years old, over the federal government's acceptable daily intake for fluoride (0.1 milligrams of fluoride per kilogram of body weight per day). In Los Angeles County alone, more than 40,000 children age 2 and under will exceed the safe dose."
"In spite of early studies implicating fluoride as a toxin, the United States began adding it to public water supplies in the 1940s. Fluoridation of Southern California's water supply was discussed and defeated by citizen opposition in 1966, 1968 and 1975. But in the late 1990s, Los Angeles began adding fluoride to the water. San Diego's Metropolitan Water District followed in December 2007."
