i just found a very interesting read by someone who from first impression at least, is pretty close to being my brain twin (except for the gluten thing. i had to avoid wheat for a while but i think it was because i was low in a couple of other things that you need for it to go down all right - i don't have trouble with it now).
anyway, a nice little overview of some of the nutrition links to ms:
there are other diet and ms things which i imagine you've been reading about like the swank diet, the best bet diet, the klenner supplement protocol, etc, which are far more complicated but those links above are kind of a good intro, i think.
AND i learned for the first time about the links between low magnesium and more severe insulin resistance. fascinating.
