Flouride and Intelligence!

According to scientific study, flouride can be detrimental to intelligence. Concerns have been identified with recommendations for further studies, in particular due to increase flouride presence in food and drinking water supplies.

When Ethical experts speak out and go to the lengths for research in the public interest, then it is always in out best interest to compare what they have to say.

"SUMMARY: The Intelligence Quotient (IQ) was measured in 512 children, aged 8–13 years, living in two villages in Sihong County, Jiangsu Province, China, differing in the level of fluoride in their drinking water.

In the high fluoride village of Wamiao (water fluoride: 2.47±0.79 mg/L; range: 0.57–4.50 mg/L), the mean IQ of 222 children was significantly lower (92.02±13.00; range: 54–126) than in the low-fluoride village of Xinhuai (water fluoride: 0.36±0.15 mg/L; range: 0.18–0.76 mg/L), where the mean IQ of 290 children was higher (100.41±13.21; range: 60–128).

The children’s IQs were not related to urinary iodine, family income, or parent’s education level.

Higher drinking water fluoride levels were significantly associated with higher rates of mental retardation (IQ <70) and borderline intelligence (IQ 70–79). The Benchmark Concentration (BMC) for the concentration-response relationship between IQ <80 and the drinking water fluoride level was 2.32 mg/L, and the lower-bound confidence limit (BMCL) of the BMC was 1.85 mg/L.

Taking dental fluorosis and other sources of dietary fluoride into account, the reference value concentration (RfC) for fluoride was calculated to be 0.925 mg/L, which is very close to the current national Chinese standard of <1.0 mg/L. In endemic fluorosis areas, drinking water fluoride levels greater than 1.0 mg/L may adversely affect the development of children’s intelligence."

"In view of reports of increased fluoride levels in many foods and water supplies, it is urgent that further studies be conducted to examine whether there is a link in animals and humans between fluoride and disturbances of the development and function of the central nervous system. High-fluoride levels may occur in artesian well water"
