Some people could be more susceptible to the influences of salt, and their genetic make-up may determine whether or not they develop MS, say researchers at the University of Vermont.
It's all a fine balancing act, say the researchers. We need enough salt to allow our body to function properly, but not too much that makes "things go haywire". People who have a genetic disposition also are more likely to develop MS.
Thus far, the research has concentrated only on mice. In their experiment, the researchers fed a high-salt diet or a normal diet to three groups of genetically-different mice. The mice that did develop signs of MS had a weakened blood-brain barrier.
