Sarah Eilers – You completely misrepresented the study by Kyle Fluegge. Instead of reading and understanding the actual paper, you apparently relied on an anti-F interpretation from a news release from Case Western Reserve University, and completely ignored two significant findings of the study:
1) Natural fluoride in drinking water “is significantly protective” of diabetes
2) “Among the three fluoridation chemicals used in this data set (sodium fluoride, fluorosilicic acid, or sodium fluorosilicate), only fluorosilicic acid was significantly and robustly associated with decreases in incidence and prevalence of diabetes.” and “Sodium fluoride produced significantly positive associations with incidence (β= 0.93, P< 0.001) and prevalence (β= 0.76, P< 0.001), whereas fluorosilicic acid and sodium fluorosilicate produced significantly negative associations respectively (fluorosilicic acid: β= –0.72, P< 0.001 and β= –0.54, P= 0.002; sodium fluorosilicate: β= – 0.55, P= 0.05 and β= –0.49, P= 0.02)."
So, the actual conclusions of Fluegge’s study would appear to be that the most commonly added fluoridation chemical, fluorosilicic acid (used in 75% of water treatment plants), seems to significantly protect against diabetes. Only 7% of treatment plants use sodium fluoride (the only additive linked to an increase in diabetes). NaF is generally only used in smaller treatment plants, so most individuals will drink water protected with fluorosilicic acid.
Actually, there are so many flaws and inconsistencies with the study that it really proves nothing.

Regarding the ADHD claims. No one has “proven” any association of optimally fluoridated water with ADHD. The Malin study you cite has been thoroughly discredited in the scientific literature for its poor methodology, inadequate control for variables, and reaching a conclusion not supported by the peer-reviewed science.
The inadequacy of controls by Malin was clearly demonstrated in a 2015 study by Huber, et al. which, using the exact data as did Malin, determined that the reported cases of ADHD were attributable to the elevation level at which the children resided, not to fluoridated water.
