WRT the Paleo diet:

I have two close friends with MS, both late 20's, diagnosed within a month of each other.

One has sought treatment with every modern medical miracle drug, yet cannot be arsed to modify her diet. Can't give up drinking, or eating crap foods - her fiancee has to continually go through the house and throw away Twinkies etc she's secreted around the place. She's in rough shape; limited mobility, lesions, the whole rotten enchilada.

The other took the opposite approach, became a champion for his own body, and has been a fierce adherent of (I think) the Wahl's diet. I know he's a lot less fun at parties due to the lack of drinking, but he's also able to be out there on the dance floor healthy and sober. He's a professional drummer, and hasn't missed a beat. He's also on no drugs for treatment.

Yes, this is purely anecdotal, and doesn't even begin to analyze any physiological differences between the two of them which might affect the disease's progression. But in my head, the logic is sound. Autoimmune disorders, the way I see it, are caused by modern living. More modern chemicals thrown at the problem aren't going to do much good. Take your body back to an environment in which these modern poisons aren't part of your biosphere, and watch your MS, Crohn's, Celiac etc go away.
