Harvard Study Suggests that Fluoride Lowers IQ
A Harvard University researchers' review of fluoride/brain studies concludes "our results support the possibility of adverse effects of fluoride exposures on children's neurodevelopment."
The study showed that, "The children in high fluoride areas had significantly lower IQ than those who lived in low fluoride areas. Fluoride readily crosses the placenta. Fluoride exposure to 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."
