When the researchers conducted spatial learning and memory tests using the Barnes maze, the aspartame mice at four months consistently moved more slowly and covered less distance during training than animals in the control group. They also took nearly twice as long on average to locate the target escape hole, showing impaired memory recall (however, this was inconsistent and not seen as statistically meaningful). By eight months, performance gaps widened even further, with two out of six aspartame-treated mice failing to complete the task at all.
It makes you dumb, unfit and fat (around the organs).
Fluoride has no known negative effects on adults in the amounts found in most drinking water.
Heavy metals and estrogens (if your area is particularly polluted? You can usually find reports of exactly how clean your local water is) are easily filtered out with a cheap undersink carbon block filter (it will also remove chlorine, as a nice side-effect).
If fluoride has no negative effects then explain why I am so stupid?
Fluoride actually can potentially, maybe have a negative effect on cognition/IQ in infants or developing children, but the research claiming that is pretty sketch. Reactions did a solid video on it, if you’re interested.
Joking aside. I go to town meetings and without fail during public comment there is always at least one anti fluoride activist.
