"It seems a gluten/diary-free diet has some effect on my energy level. It is very difficult in this society to keep this sort of diet, but this and the "paleo" diet seem to be helpful. Not for symptoms like mobility issues or incontinence, but energy and sleeping. I would like to have more information about this and how it works and any studies being done about MS and diet."
The following link is a search of all current studies listing at the Federal Government Clinical Trials registration site assessing diet in Multiple Sclerosis. I believe the only study recruiting patients is at the University of Iowa testing both Gluten free and paleo diets.
We do not know how these diets work or if it is just a placebo effect but many people with MS report improved energy and well being.
