Fluoride Study Show Chemical Lowers IQ In Fetuses
For those who oppose fluoridation in public tap water, a recent study is being called “the biggest moment in the history of this whole debate.” And it also has health officials scrambling to make up excuses. A new study links fluoride consumption during pregnancy to lower IQs in children.
According to the National Post
“There are some pretty bizarre theories out there, such as the idea that fluoride is being used to sedate the population,” said University of Alberta health policy researcher Tim Caulfield.
“I worry that this study — which the authors note should be replicated, and they call for further analysis and research — will be presented as definitive. It is not.”
The study, which used children in Mexico using 300 mothers and their children, suggested that fluoride is a neurotoxin for children at ages 4, and 6 to 12 years of age. The science suggest a link between prenatal exposure and cognitive development.
We had complete data on 299 mother–child pairs, of whom 287 and 211 had data for the GCI and IQ analyses, respectively. Mean (SD) values for urinary fluoride in all of the mothers (n=299) and children with available urine samples (n=211) were 0.90 (0.35) mg/L and 0.82 (0.38) mg/L, respectively. In multivariate models we found that an increase in maternal urine fluoride of 0.5mg/L (approximately the IQR) predicted 3.15 (95% CI: −5.42, −0.87) and 2.50 (95% CI −4.12, −0.59) lower offspring GCI and IQ scores, respectively.
CONCLUSIONS:In this study, higher prenatal fluoride exposure, in the general range of exposures reported for other general population samples of pregnant women and nonpregnant adults, was associated with lower scores on tests of cognitive function in the offspring at age 4 and 6–12 y.
Fluoride is found in a variety of our products, including toothpaste, tap water, and even milk. It is almost impossible to avoid, particularly when you do not understand the sources. Most products are labeled with fluoride if the product contains the ingredient. However, tap water is almost unavoidable. We shower in it, we brush our teeth in it, and we wash our faces in it. And of course, for some families, it is used as the main hydration source. The core competency of the argument is that fluoridation should be a choice, not a mandate. By putting it into our natural water resource, we are essentially mandating it.
Children scored 2.5 to three points lower on IQ tests for every 0.5 milligram-per-litre increase in their mother’s urinary fluoride levels beyond 0.8 mg/L.
Researchers say that children’s test scores were not affected depending on levels of urine tested. This means that the test showed a definitive issue when the child was in the womb, more than after the birth. In Mexico, most people are advised to avoid tap water for purposes beyond the scope of fluoridation. Many women, however, are exposed to fluoride via salt. Mexico has been fluoridating salt since the early 90s. Researchers also made specific adjustments based on a woman’s history of smoking, lead exposure and income. Furthermore, the researchers didn’t consider the Mexican women’s fluoride urine levels to be ultra-high.
“there still may be a level of fluoride exposure among both pregnant women and everybody else that can still preserve the beneficial effects on tooth decay, while avoiding any effects on intelligence,” said Dr. Howard Hu, the study’s principal investigator and founding dean of the University of Toronto’s Dalla Lana School of Public Health.
Let’s face it, if you live in the United States, you almost surely have some level of fluoride intake even if you do your best to avoid it. Worse more? Even our friends at CNN are reporting this story. When CNN is covering “conspiracy,” the herd should most definitely worry. Even the best survival water filters don’t always help you out.
“Childhood exposure to fluoride is safer than prenatal. There is pretty good science now to support the fact that the fetal system tends to be more sensitive to environmental toxicants than once the child is born,” said the study’s lead author, Howard Hu.
That’s somewhat of a horrendous statement when you think about it. That’s essentially placing prenatal exposure to fluoride into a massively questionable realm (at best).
