Fluoride lowers kids intelligence

There is increasing evidence emerging from the scientific community which suggests that mass-medication in the form of water fluoridation is in fact having a serious and adverse effect on the public’s health. A recent report from the US National Research Council 1 concluded that adverse effects of high fluoride concentrations in drinking-water may be of concern. Animal studies have shown Fluoride may cause neurotoxicity, including effects on learning and memory 2,3. Recent experiments where the rat hippocampal neurons were incubated with various concentrations of sodium fluoride showed that fluoride neurotoxicity may target hippocampal neurons.

Fluoride readily crosses the placenta exposing the developing brain, which is much more susceptible to injury caused by toxicants than is the mature brain, may possibly lead to damage of a permanent nature 4

 In a study conducted by Tianjin Medical University in China, a comparison in the Intelligence Quotient (IQ) was measured between 60 children living in a high fluoride area and 58 children living in a low fluoride area. The IQ of the 60 children living in the high fluoride area was lower than that of the 58 children living in the low fluoride area. 21.6% of the children in the high fluoride area were retarded compared to 3.4% of retarded children living in the low fluoride area 5.  

 In a study at Tokyo University Medical School, water fluoridation was linked to Down syndrome. The study found that - as well as the aging of mothers - the number of excess Down syndrome births caused each year by water fluoridation was estimated to be several thousand cases throughout the world 6.

 In the most recent meta analysis of 27 eligible epidemiological studies found that children in high fluoride areas had significantly lower IQ scores than those who lived in low fluoride areas 7. The conclusions of the study “support the possibility of an adverse effect of high fluoride exposure on children’s neurodevelopment.”

 Some of the other adverse health effects of fluoride include lowered levels of collagen synthesis, depleted energy reserves and lowered immunity, irritable bowel syndrome,thyroid disorders, Skeletal fluorosis, Osteosarcoma, Osteoporosis and bone fractures as well as Alzheimer's disease.
