There's something called "The Mini Beet Protocol" by Robert Von Sarbacher that's worth checking out.

and especially the feedback on Earth Clinic:

OK, this is essentially a method to remove Fluoride from the body, however on one of the comments (11/17/2009), Lisa from Thousand Oaks, Ca, USA writes:
To everyone suffering with body pain/arthritis- it's due to too much cooked food and not enough raw veggies/greens and fruit. It all has to do with the enzymes that our body really needs. Since embarking on this, I have tried eating cooked food meals 3x and about a half hour afterward the pain immediately returns. It is so debilitating that as of last night, my husband said to me, "That's it, I think we can see a direct correlation between your physical pain and the food."
Robert Von's site (http://robertvon.com/) also has two (long) radio interviews that provide a wealth of information on healthy living.
