Recent Study Shows Fluoride Lowers Our IQs and Prevents Brain Development

Here we go – MORE dastardliness exposed – Fluoride in the water, toothpaste etc foisted upon humanity – look what it does to us.

Sure, we already knew fluoride was dangerous, but the more I look into it the more upsetting it is. Why is this being added to our water?

I recently came across a study published in the Institute of Environmental Health Sciences journal Environmental Health Perspectives shows that fluoride actually damages our brain and the way it develops. This is something that causes significantly lower IQ levels in humans. Yes, you could possibly have been much smarter than you are now if it weren’t for all that fluoride in the water if you want to look at it that way.

For this study, researchers from China Medical University in Shenyang and Harvard University’s School of Public Health worked together to study the effects of fluoride on children by evaluating 27 different fluoride studies. They reviewed each one intensively and found that there are without a doubt strong indications that fluoride exposure in children, in particular, is HIGHLY problematic. They found it dramatically affects proper cognitive development and brain formation from a young age. It seems children who live in areas where the water supplies are artificially fluoridated had far lower IQs than those in non-fluoridated areas.

The abstract of their study goes as follows:

Background: Although fluoride may cause neurotoxicity in animal models and acute fluoride poisoning causes neurotoxicity in adults, very little is known of its effects on children’s neurodevelopment.

Objective: We performed a systematic review and meta-analysis of published studies to investigate the effects of increased fluoride exposure and delayed neurobehavioral development.

Methods: We searched the MEDLINE, EMBASE, Water Resources Abstracts, and TOXNET databases through 2011 for eligible studies. We also searched the China National Knowledge Infrastructure (CNKI) database, because many studies on fluoride neurotoxicity have been published in Chinese journals only. In total, we identified 27 eligible epidemiological studies with high and reference exposures, end points of IQ scores, or related cognitive function measures with means and variances for the two exposure groups. Using random-effects models, we estimated the standardized mean difference between exposed and reference groups across all studies. We conducted sensitivity analyses restricted to studies using the same outcome assessment and having drinking-water fluoride as the only exposure. We performed the Cochran test for heterogeneity between studies, Begg’s funnel plot, and Egger test to assess publication bias, and conducted meta-regressions to explore sources of variation in mean differences among the studies.

Results: The standardized weighted mean difference in IQ score between exposed and reference populations was –0.45 (95% confidence interval: –0.56, –0.35) using a random-effects model. Thus, children in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas. Subgroup and sensitivity analyses also indicated inverse associations, although the substantial heterogeneity did not appear to decrease.
