High fluoride levels could be lowering people’s IQ
The debate over whether or not we should be putting fluoride in our drinking water has been going on for years, with some saying that it’s a good thing, and others saying that we need to remove it. However, most people agree that, at the very least, we need to find out how much fluoride is considered safe and healthy.
A recent study that was published in Environmental Health Perspectives has found that high levels of fluoride in the drinking water in some parts of Maine could be lowering the IQ of residents by around seven points, especially in children. There are also areas like Philadelphia that are concerned that the increase in cases of neurological disorders such as autism and ADHD could be linked to fluoride.
The recent study discovered that somewhere around ten communities in Maine have private wells with water that has dangerously high levels of fluoride. Some wells were even found to have almost twice the prescribed level of the United States Environmental Protection Agency (EPA). All in all, the majority of the wells were found to have far more than the acceptable maximum level of exposure.
Researchers from Harvard University have conducted a review on numerous studies on the effects of fluoride on the brain. The researchers found that there is significant evidence that fluoride exposure can have adverse effects on the neurodevelopment of children. It has also been reported that fluorides have the ability to interfere with the functions of the brain.
