This benefit is dubious at best, as there is practically no difference in tooth decay rates between fluoridated and non-fluoridated countries, and no difference between states that fluoridate a high versus low percentage of their water.
Yet, while fluoride in drinking water does NOT decrease rates of tooth decay, numerous studies show that this chemical has a wide array of devastating health effects – one of them being lowered IQ.
Yet Another Study Links Fluoride to Lower IQ Levels
A review of brain studies involving the use of fluoride has concluded that one of the adverse effects of fluoride exposure on children is damage to their neurological development.1 According to the Harvard researchers, children who lived in high-fluoride areas had “significantly lower IQ than those in low fluoride areas,” with the authors noting:
“The results support the possibility of an adverse effect of high fluoride exposure on children’s neurodevelopment.“
This just adds to the growing number of animal and human studies demonstrating the damage fluoride inflicts on your brain, including your pineal gland. The results of one study looking at children’s intelligence in two towns – one with fluoridated water and one without – were particularly revealing, with about 28 percent of the children in the low-fluoride area scoring as “bright, normal or higher intelligence” compared to only 8 percent in the high-fluoride area.2
Further, 15 percent of children in the high-fluoride city had signs of mental retardation, compared with only 6 percent in the low-fluoride city. And the study even accounted for other potential variables, such as lead exposure, iodine deficiency or a history of brain disease or head injury. There have been over 23 human studies and 100 animal studies linking fluoride to brain damage.
