  • Dude, that’s for the odds someone might have hypothyroidism, not at all related to toxicity.

    And as noted by the authors:

    “Hence, the application of standard household water purification (such as reversed osmosis, electro dialysis, activated carbon filter, and other adsorption/ion-exchange methods) is recommended for patients with hypothyroidism since they have a higher consumption of drinking water. The purification systems can help remove fluoride that interferes with thyroid functions.”

    So, if you have a family history of hypothyroidism, and you care at all about trying to avoid this incredibly common and easily treatable issue; use a water filter. It probably won’t help since family history and regular exercise are much more highly correlated with the incidence of hypothyroidism, but sure, why not.

    Also, and this is fun, they conveniently ignore the fact that the people drinking the most water (5+ cups group) have a lower adjusted-odds-ratio (OR) of hypothyroidism.

    How about the part where the level of fluoride in the water being in the higher end of the spectrum (0.3-0.5 mg/L) gives you a *checks notes* oh yeah, 3.4% higher incidence rate of hypothyroidism. Right.


  • If the stupid motherfucker brushes his teeth twice daily, he’s already introducing loads more fluoride to his body than any of the trace amounts they add into the public water system, which is still standards of deviation less than anything that would introduce fluorosis of childrens’ teeth (since that’s not possible for adults with developed teeth), let alone get to a level of toxicity for an adult.

    Now, if he regularly consumes full tubes of toothpaste as a health supplement, then maybe that’s a reason to be concerned about fluoride.
