27 Studies Show Fluoride Causes Negative Brain Development In Children



The debate over fluoride and water fluoridation has raged on for decades, and will likely continue to do so for years to come unfortunately. Numerous health concerns associated with fluoride consumption have been brought to light over time, and little to no action has been taken. Its been a well-known fact that neurotoxic effects can take place in adults who are exposed to extremely high levels of fluoride, but getting all the experts to agree on what the risks are and how dangerous they can be has always seemed to be a pipe dream. However, with new data at their disposal that could all be changing very soon.

A total of 27 studies have been combined into a large meta-analysis by both China Medical University in Shenyang and the Harvard School of Public Health (HSPH) that found many strong indications that fluoride can have negative effects on cognitive development of children. Study authors say that though the findings are inconclusive, they should not be ignored. In fact, they say that these findings warrant even further, more developed studies on the relationship between excessive fluoride consumption and human brain development. Rodent studies had always yielded negative results on memory and learning, but there are virtually no studies of this nature done in the US.

The combined studies all took place in China, and included over 8,000 children of school age up to age 14. All of these studies but one indicated negative developmental effects associated with higher fluoride content in water supplies. Some of the studies suggested that even slightly increased exposure could be toxic to the human brain. Also, children in the higher fluoride areas had significantly lower IQ scores than those living in lower fluoridated areas.

 

Senior author Philippe Greanjean, adjunct professor of environmental health at Harvard School of Public Health stated that Fluoride seems to fit in with lead, mercury, and other poisons that cause chemical brain drain. The effect of each toxicant may seem small, but the combined damage on a population scale can be serious, especially because the brain power of the next generation is crucial to all of us.
