Salt is found in many foods, including bread.
The amount of salt in our diet could cause our immune system to rebel against us, exposing us to diseases such as multiple sclerosis (MS), according to preliminary results of an international investigation.
Several teams of scientists have simultaneously published data in the scientific journal Nature suggesting the relationship between the mineral and the immune system.
Salt can activate a part of the immune system that could attack the body.
Experts say the results are interesting and reasonable, but it does not mean that this fact allows them to be closer to a cure for patients with multiple sclerosis.
The body's defenses against an infection can be terrible, causing it to change and leading to autoimmune diseases such as type 1 diabetes, rheumatoid arthritis and MS.
It is believed that genetic factors increase the predisposition for these diseases, but the influence of the environment should not be ruled out.
