I hope most people with MS know that high salt intake is very problematic for MS.

Here's another reason to put the salt shaker down: New research in The FASEB Journal involving mice shows that diets high in sodium may be a novel risk factor in the development of multiple sclerosis (MS) by influencing immune cells that cause the disease.
