Prenatal Fluoride Exposure Associated with Increased Neurobehavioral Problems

Researchers from the Keck School of Medicine of USC conducted the first U.S.-based study examining the link between prenatal fluoride and childhood social, emotional and behavioral functioning.

A new study, led by researchers at the Keck School of Medicine of USC and funded in part by the National Institutes of Health, analyzed more than 220 mother-child pairs, collecting data on fluoride levels during pregnancy and child behavior at age three. The researchers found that a 0.68 milligram per liter increase in fluoride exposure was associated with nearly double the chance of a child showing neurobehavioral problems in a range considered close to or at a level to meet the criteria for clinical diagnosis.

These population-level findings add to existing evidence from animal studies showing that fluoride can harm neurodevelopment, as well as data from studies conducted in Canada, Mexico and other countries showing that prenatal exposure to fluoride is linked with a lower IQ in early childhood. …

“This is the first U.S.-based study to examine this association. Our findings are noteworthy, given that the women in this study were exposed to pretty low levels of fluoride—levels that are typical of those living in fluoridated regions within North America,” said Ashley Malin, PhD, an assistant professor of epidemiology at the University of Florida’s College of Public Health and Health Professions and College of Medicine and lead author of the present study.

“There are no known benefits to the fetus from ingesting fluoride,” Malin said. “And yet now we have several studies conducted in North America suggesting that there may be a pretty significant risk to the developing brain during that time.”

chatgpt provided some methods for removing fluoride:

Proven methods for removing fluoride from tap water include:

  1. Reverse Osmosis (RO): This filtration method effectively removes fluoride by forcing water through a semi-permeable membrane, leaving contaminants behind.
  2. Activated Alumina: Filters containing activated alumina can adsorb fluoride from water, reducing its concentration.
  3. Distillation: This process involves boiling water and condensing the steam, leaving fluoride and other impurities behind.
  4. Bone Char Carbon: This type of filter uses charred animal bones to remove fluoride through adsorption.

Each method has its advantages and potential drawbacks, such as cost, maintenance, and water wastage.
