According to a new Canadian study, children consuming formula constituted with fluoridated drinking water shows a substantial drop in IQ. The research paper shows a decrease of 4.4 IQ points with every 0.5 mg/L increase in fluoride concentration in water. Moreover, this result came from the observation of preschool children who consumed formula during the first six months of their lives. Scientists did not find any association between the IQ of breastfed children and formula-fed children.
Furthermore, the study shows that exposure to Fluoride has a significant impact on non-verbal intelligence than on verbal intelligence. The co-author noted that using optimal fluoride water to reconstitute infant formula might diminish the development of intellectual abilities in young children.
A team of researchers examined almost 400 mother-children pairs. And was a part of Maternal-infant Research on Environmental Chemicals project? They tested the municipal drinking water in the resident cities. They broke down the water to 38% fluoride and 62% non-fluoride. Moreover, they asked questions to the mothers of children between 30 to 48 months about infant feeding. They also requested the timings and duration of the formula vs. breastfeeding vs. a combination of the two.
The fluoride exposures were estimated via municipal water treatment data and the feeding data from breastfed and formula-fed subjects. Further, researchers assessed the IQ via Wechsler Preschool and Primary Scale of Intelligence-III.
Fluoride could be beneficial during teeth eruption in children. However, the fluoride water is not helpful for infants whose primary teeth do not erupt. The result of the study shows that formula-fed infants who reside in fluoridated areas have a 70-fold higher intake of Fluoride than exclusively breastfed infants.
Moreover, formula-fed infants also retain more Fluoride than breastfed infants because infants have a limited capacity to excrete Fluoride before renal function reaches its full capacity at about two years of age. The estimated fluoride intake may be more in the children as researchers did not add the fluoride intake from other sources. Even children’s toothpaste and foodstuff also have fluoride content. Hence, children’s IQ could be in danger due to excess fluoride intake.
