I'm basically in agreement with you that fluoride is "very bad"
However One of the annoying things is that fluoride is really difficult to get out of your body or even the water you are drinking.
However, the following things are thought to help;
1) Limit your exposure:
The best way to do this besides getting a reverse osmosis filter (or moving to utah/hawaii as they are the only states which do not fluorinate) is to
Additionally, fluoride bioaccumulates, so it's most prevalent in processed foods, and the most infrequent in organic produce. As such, shifting your diet towards there can help.
2) Eating enough iodine (this will replace fluoride stored in the body, although it does so primarily in the thyroid not the pineal).
3) Eating colloidal or monotomic gold. I don't have any first hand experience here, but I've met a lot of people that told me it works (basically gold will only react with fluoride, and once paired with it, will not displace fluoride into another compound, but will take fluoride out of another metal complex, and AuF is harmless and get's excreted by the body, hence overtime it will take it out of the body). I never followed through on this (due to cost), but it's supposed to be the best way to deal with it.
4) Reduce your exposure to aluminum and mercury as much as possible. Fluoride is the most damaging when it combines with either of those two.
I have heard homeopathic stuff works for fluoride BUT I have no actual first hand verifiation of it being true. If it did, that would be really nice and solve the problem, but thusfar I have not come across anything confirming that.
To some extent completely avoiding fluoride is impossible tho, so I would instead advocate doing something else to compensate for it. I come from the Taoist tradition, so I advocate some of their better stuff, and if you're interested I can pass that along to you (which will also help a lot for joint stiffness).
hope that helps!
