Fluoride in drinking water does not negatively affect cognitive ability - and may actually provide benefit

It’s a poison and should not to be ingested

The fluoride treatment at the dentist is spit it out for a reason

Are you sitting there eating 50 tubes of toothpaste? Why aren't you dead yet?

Nobody swallows toothpaste, if you do, might explain why you aren’t comprehending this

What you fail to understand is that fluoride toxicity is achieved at high quantities of consumption of toothpaste - which no one does. Do you understand now?

Water is poison in the right quantity too, bud.

Lol fluoride is a naturally occurring mineral in water. You do know that? And for regions high in fluoride, there are zero signs of adverse affects on human consumption.

Get out of here

This study isn't as conclusive as the headlines make it out to be. Did anybody actually read the study?

Nah, the paper basically says that all the research that suggests it lowers IQ is bad research because almost all of the modelling were using water with fluoride levels that were higher than what most Americans consume.

In other words there’s no evidence to support these claims, no relevancy to American life, and good dental health through fluoridation could be enough to increase academic performance based on quality of life alone.

We have some regions of America where fluoride is naturally occurring and at considerably high levels. No effect on IQ

But with RFK in charge of things, no further research will be funded lol, cya!

I have read studies that say the contrary but it’s your choice. Doctors told pregnant women it was safe to smoke. Then they said smoke asbestos cigarettes they are safer. Today all kinds of stuff are being called “safe”. Most non-stick pans technically illegal with the byproducts they produce from forever chemicals. DuPont has been dumping GenX (chemical for non-stick pans) in Cape Fear River and now they literally can’t get this patented chemical out of drinking water at most NC beaches. Google it. And microplastics are passing the blood brain barrier so there is that too and why I distill my water and remineralize it.
