The study, published in PNAS, examined Wisconsin state testing records, archival information about when Wisconsin cities began to fluoridate their water, and data from the Wisconsin Longitudinal Study, which has followed a random sample of 10,317 high school seniors from 1957 through 2026. Key findings include:
- There is no evidence supporting a connection between community water fluoridation and children’s IQ.
- There is also no evidence supporting a connection between community water fluoridation and cognitive functioning at various points later in life.
- Findings confirm evidence published in previous research which also used a national sample, but considered school achievement test scores instead of actual IQ scores.
Again. I’m arguing for the benefits of fluoridation…
Many prior studies link reduced teeth rot to mental wellness, cognitive function, less cardiac issues, lower risk of stroke, less inflammation, less depression, and on and on.
There’s cross species studies on this.
Feeding pigs sweets “taints the meat” and the hogs start acting weird, often violent, and antisocial.
And indeed, trans species obvious basic biology… Diabetes is real. Etc. Excessive sugar doesn’t just rot teeth, it rots the whole body, including the brain.
