Salt is not sodium chloride
Sodium chloride is a chloride which is combined with sodium , but salt not only contains sodium chloride , but also dozens of minerals including potassium , calcium , magnesium , iron , copper , manganese , zinc , silicon , and sulfur , etc . Out of all minerals , salt is most similar in composition to that of human body , and almost all minerals we need are dissolved in it .
The human body needs sodium to carry oxygen and nutrients but cannot produce sodium on its own . Without sodium transmitting nerve impulses and moving muscles including the heart would also be impossible . If we lack chlorine , producing gastric juice becomes difficult , which would make it difficult for us to digest fat in food .
Moreover , in order to activate various enzymes , manganese , zinc , and magnesium are required , and potassium is absolutely necessary to maintain the balance of sodium . If there is no copper , even the production of blood is not possible , and if there is insufficient calcium , we can have problems with nerve transmission .
As we have examined , salt is absolutely necessary for digestion , and other metabolic functions in our body . If the various minerals do not make proper chemical reactions and facilitate the metabolism of the body , it is impossible to sustain life . In other words , salt is the very substance that enables us to continue our life ’ s activities . If we don ’ t eat salt , even for a few days , it can be a serious threat to our life .
