Fluoride Harms Children's Liver & Kidneys, study shows:

New York -- August 2006 -- Fluoride in drinking water damages children's liver and kidney functions, according to a new study in Environmental Research(1)

Xiong and colleagues write,“Our results suggest that drinking water fluoride levels over 2.0 mg/L can cause damage to liver and kidney functions in children.” Further, dental fluorosis (fluoride-discolored teeth) can be an indicator of kidney function harm, they report.

Researchers grouped 210 Chinese children (aged 10 – 12 years old) by drinking water fluoride levels (averaging 0 .76; 1.47; 2.58; and 4.5l mg/L). Dental fluorosis rates, respectively, were 15%, 41%, 79% and 94%.


Blood serum and urine samples revealed:-- fluoride levels increased as water fluoride levels increased

-- liver and kidney enzymes elevated, indicative of liver or kidney damage, in children drinking water with over 2mg fluoride per liter.-- liver function can be damaged without dental fluorosis

"Dose-effect relationship between water fluoride levels and damage to liver and kidney functions in animals has been reported," the authors write. However, this is one of the few to do so in humans. The liver and kidneys are especially susceptible to fluoride toxicity, they write.
