[no idea]

Table salt is not just sodium chloride, it has other type of salt. You should read the ingredient list on the side of salt box.

Yes, this kind of salt is specially prepared so that the overall sodium chloride percent is low. They are using potassium chloride, calcium chloride and magnesium chloride, as I know.

Low sodium in salt's more important from a physiological point of view as sodium causes water retention and therefore increases blood pressure. Potassium, calcium etc don't and therefore don;t carry the same risks for cardiovascular disease.
