(NaturalNews) A new study pre-published in the journalconfirms that fluoridated water causes brain damage in children. The most recent among 23 others pertaining to fluoride and lowered IQ levels, the new study so strongly proves that fluoride is a dangerous, brain-destroying toxin that experts say it could be the one that finally ends water fluoridation."This is the 24th study that has found this association," explained Paul Connett, Ph.D., director of the Fluoride Action Network (FAN). "[B]ut this study is stronger than the rest because the authors have controlled for key confounding variables and in addition to correlating lowered IQ with levels of fluoride in the water, the authors found a correlation between lowered IQ and fluoride levels in children's blood."For the study, researchers evaluated 512 children ages 8-13 in two Chinese villages, one village with higher than average fluoride levels and the other with lower than average fluoride levels. After accounting for external variables like lead exposure, iodine deficiency and other conditions that might affect brain health, the team still found that the number of higher intelligence children in the low fluoride community was 350 percent higher than the number in the high fluoride community."In this study we found a significant dose-response relation between fluoride level in serum and children's IQ," wrote the study authors.Though there have been numerous studies over the years the identify fluoride as a neurotoxin, most mainstream medical professionals in the U.S. have ignored them and continue to support water fluoridation. But the evidence continues to mount, and sooner or later the medical community will have to come to grips with the truth about fluoride."This should be the study that finally ends water fluoridation," explained Tara Blank, Ph.D., Science and Health Officer at FAN. "Millions of American children are being exposed unnecessarily to this neurotoxin on a daily basis. Who in their right minds would risk lowering their child's intelligence in order to reduce a small amount of tooth decay, for which the evidence is very weak."To learn more about the dangers of fluoride, visit:
