I believe the objection to fluoride is that it is a tranquilizer that keeps us from achieving glory through violent uprising... or sweet sweet dentist profits.

For what’s it worth, in my country (Netherlands), we don’t add fluoride to our tap water anymore since the early 70s. We just have it in our toothpaste (though you can also get fluoride free toothpaste for those who don’t want it).

Sure there’s still traces of fluoride in our water, as it appears in nature. But it’s not artificially added by our water companies.

How much oatmeal would I have to eat to die of fluoride poisoning?

[–] piecat@lemmy.world 9 points 7 months ago* (last edited 7 months ago) (1 children)

0.08mg per half cup serving, but may vary depending on water used. https://ods.od.nih.gov/factsheets/Fluoride-HealthProfessional/

10mg is the accepted daily upper limit for an adult. So 62.5 cups of oatmeal to reach that max safe limit. https://ods.od.nih.gov/factsheets/Fluoride-Consumer/

Acute poisoning symptoms may appear as low as 10-15 mg/kg, lethal dose might be 32-64 mg/kg. https://en.wikipedia.org/wiki/Fluoride_toxicity

So 200 to 400 cups of oatmeal per kg you weigh for a lethal dose. (32/0.08/2=200, 64/0.08/2=400)

That's a lot of oatmeal.

I had the misfortune of eavesdropping on a conversation recently where some guy who was working in a bourgeoisie brewing facility recently switched jobs to work at a waste water treatment center and he was advocating for removing fluoride from water with a level of rationale that I have to assume he picked up from co-workers parroting information they heard on the Joe Rogan podcast.
