There are so many known diseases out there but not all has known cure just like Multiple Sclerosis, an inflammatory disease in which the fatty myelin sheaths around the axons of the brain and spinal cord are damaged. It affects the ability of nerve cells in the brain and spinal cord to communicate with each other. Once myelin is lost, the axons cannot effectively conduct signals anymore.
It's hard to tell when such disease strikes with such unknown cause and cure. Experts recommend MS diet which is not too far from any other diet. It is more of a balance of variety of foods; limit of fats, sugar and sodium; and if alcohol cannot be avoided, have it in moderation.
