Fluoride in Water Linked to Lower IQ in Children

A new study shows that exposure to fluoride may lower children‘s intelligence. Fluoride is added to 70 percent of U.S. public drinking water supplies...click & see the pictures

More than 500 children aged 8 to 13 from two different towns were studied and tested.  One city had fluoridated water, and the other did not.

PR Newswire reports:
“About 28 percent of the children in the low-fluoride area scored as bright, normal or higher intelligence compared to only 8 percent in the ‘high’ fluoride area … in the high-fluoride city, 15 percent had scores indicating mental retardation and only 6 percent in the low-fluoride city.”

CDC and ADA Now Advise to Avoid Using Fluoride

It was 2007 when the American Dental Association (ADA) first warned that parents of infants younger than a year old “should consider using water that has no or low levels of fluoride” when mixing baby formula, due to concerns about fluorosis.

Now the Journal of the American Dental Association has published a study that found increased fluorosis risk among infants who were fed infant formula reconstituted with fluoride-containing water, as well as used fluoridated toothpastes.

A new study in the Journal of the American Dental Association finds once again that, contrary to what most people have been told, fluoride is actually bad for teeth.

Exposure to high levels of fluoride results in a condition known as fluorosis, in which tooth enamel becomes discolored. The condition can eventually lead to badly damaged teeth. The new study found that fluoride intake during a child’s first few years of life is significantly associated with fluorosis, and warned against using fluoridated water in infant formula.

The Centers for Disease Control and Prevention (CDC) is of a similar opinion. According to their website:

“Recent evidence suggests that mixing powdered or liquid infant formula concentrate with fluoridated water on a regular basis may increase the chance of a child developing … enamel fluorosis.”

Fluoride

Fluoride is a compound consisting of fluorine and one or more other elements. It occurs naturally in the body as calcium fluoride and is found primarily in the bones and teeth.

Why do you need it?
Small amounts of fluoride help reduce tooth decay. Studies have shown that fluoridated water supplies can reduce dental caries in children by 50 to 60%. Fluoride is also involved in the maintenance of bone structure.

How much fluoride should one take?
There is currently no recommended daily allowance (RDA) for fluoride. However, the National Academy of Sciences has deemed the following amounts to be safe and adequate in a normal diet:

*Adult men: between 1.5-4.0 milligrams/day
*Adult women: between 1.5-4.0 milligrams/day
*Children aged 7-10: between 1.5-2.5 milligrams/day
*Infants: between 0.1-1.5 milligrams/day
*Pregnant/lactating women: 3.0 milligrams/day


What are some good sources of fluoride?


The best source of fluoride is fluoridated water, which is available in about half of all households in the United States
. Foods prepared with fluoridated water will also contain fluoride. Natural fluoride is present in the ocean as sodium fluoride, so most seafood contains some form of fluoride. Tea and gelatin are also good sources.

What can happen if you don’t get enough fluoride?
The most recognizable symptom of fluoride deficiency is an increased incidence of tooth decay, especially in children. Unstable bones and teeth are other signs of a lack of fluoride.

What can happen if you take too much?
Large quantities of fluoride intake can result in dental fluorosis, a condition in which tooth enamel becomes dull and unglazed with some spotting. At very high concentrations, dark stains may appear on the teeth. Although unsightly, these teeth rarely have any dental caries. Fluoride intake of 20 to 80 milligrams per day over a period of many years can cause skeletal fluorosis, which causes the bones to be chalky and brittle.
