A rise in autoimmune diseases like m-s may be a result of too much salt in our diet.
Researchers at Yale University used mice to understand how salt, and genes interact with the immune system. They found mice fed a high-salt diet made more cells associated with an immune system attack on the body.
The mice were also more likely to develop worse forms of multiple sclerosis, an autoimmune disease.
Genes already found to play a role in these diseases were responsible for the salt reaction.
