Fluoride: The Hard to Swallow Truth

“Fluoride seems to fit in with lead, mercury, and other poisons that cause chemical brain drain,” Grandjean says. “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.” For years health experts have been unable to agree on whether fluoride in the drinking water may be toxic to the developing human brain. Extremely high levels of fluoride are known to cause neurotoxicity in adults, and negative impacts on memory and learning have been reported in rodent studies, but little is known about the substance’s impact on children’s neurodevelopment. In a meta-analysis, researchers from Harvard School of Public Health (HSPH) and China Medical University in Shenyang for the first time combined 27 studies and found strong indications that fluoride may adversely affect cognitive development in children. Based on the findings, the authors say that this risk should not be ignored, and that more research on fluoride’s impact on the developing brain is warranted.

Future research should formally evaluate dose–response relations based on individual-level measures of exposure over time, including more precise prenatal exposure assessment and more extensive standardized measures of neurobehavioral performance, in addition to improving assessment and control of potential confounders. http://ehp.niehs.nih.gov/1104912/

A call for reducing fluoride levels in drinking water Controversy over fluoride levels in drinking water in Massachusetts has made headlines in recent months as Cambridge, Gloucester, Newburyport, and other towns in Massachusetts relook at the decades-old practice of adding fluoride to public drinking water to reduce dental caries (cavities). Some of the controversy between scientists, dental professionals, anti-fluoride activists, town officials, and others in Massachusetts and across the U.S. might be reduced if the U.S. Health and Human Services (HHS) proposal for lowering fluoride levels in U.S. drinking water was finalized, according to a Harvard T.H. Chan School of Public Health researcher. “I know that [the Department of] Health and Human Services in Washington has recommended that [U.S. communities] decrease the level of fluoride in water from 1.0 part per million to 0.7 parts per million. I think we ought to do that right away,” Philippe Grandjean, adjunct professor of environmental health, said on WBUR’s Radio Boston on February 5, 2015. Close to 75% of the U.S. population receives drinking water containing 0.7-1.2 parts per million (ppm) fluoride to prevent tooth decay, levels that were based on recommendations from the federal government made more than four decades ago. The decision to add fluoride to a water supply is made by local or state governments. According to data reported to the Centers for Disease Control and Prevention, communities in Massachusetts generally add fluoride to arrive at a concentration of 1.0 part per million (ppm) to their drinking water. “Just because we did studies over the last 70 years, it doesn’t mean that we did everything that is necessary to know for sure that fluoridation is not toxic to some processes in the body or development of the brain. Those studies have actually not been done,” said Grandjean, also head of the Research Unit at the University of Southern Denmark and author of Only One Chance: How Environmental Pollution Impairs Brain Development – and How to Protect the Brains of the Next Generation.

Fluoride water 'causes cancer'

Boys at risk from bone tumours, shock research reveals

Fluoride in tap water can cause bone cancer in boys, a disturbing new study indicates, although there is no evidence of a link for girls.

New American research suggests that boys exposed to fluoride between the ages of five and 10 will suffer an increased rate of osteosarcoma - bone cancer - bet-ween the ages of 10 and 19.

In the UK, fluoride is added to tap water on the advice of bodies such as the British Dental Association. The Department of Health maintains that it is a cost-effective public health measure that helps prevent tooth decay in children.

About 10 per cent of the population, six million people, receive fluoridated water, mainly in the Midlands and north-east, and the government plans to extend this, with Manchester expected to be next. About 170 million Americans live in areas with fluoridated water. Read More: http://www.theguardian.com/society/2005/jun/12/medicineandhealth.genderissues
