Fluoride. A controversial topic with polarizing views. Dentists say fluoride protects your teeth against cavities and prevents tooth decay. However, a new study, published September of this year, claims that increased levels of prenatal fluoride exposure may be associated with a lower cognitive function in children!
A study found in the Environmental Health Perspectives studied 300 sets of mothers and children in Mexico. They tested the children twice in twelve years for cognitive development. While fluoride is not added to public water in Mexico, people are still exposed to naturally occurring fluoride in water, fluoridated salt, toothpaste, tea, and supplements.
For every .5 milligram-per-liter increase in fluoride exposure beyond .8 milligrams per liter found in urine, there was a slight drop in the intelligence test scores. The researchers found a potential connection to exposure to fluoride in utero, however, no significant influence was discovered once a child was born.
Neurotoxin & Lowers IQ
A neurotoxin is something that is poisonous or destructive to the tissues in the brain, spinal cord, and nervous system. Some claim fluoride may be a neurotoxin, however, many of those doing research on this topic say more research needs to be done to confirm or show otherwise.
Some 180 studies show fluoride is linked to neurotoxic harm and reduced IQ in children. They found that fluoride can potentially cause:
- Brain damage
- Reduced IQ
- Impaired ability to learn and remember
- Neurobehavioral deficits
- Impaired fetal brain development
Guess where our main source of fluoride comes from? Yep. Water. 75% of Americans are exposed to fluoride through the public water. Other common places are in our toothpaste and mouth rinses. It is difficult, but not impossible to avoid these fluoride avenues. And according to this research, it may be important to do so when you are expecting.
