Salt is a mineral that consists primarily of sodium chloride (NaCl), a chemical compound that belongs to the larger class.
As a crystalline mineral, it is naturally known as rock or halite. Seawater contains a large amount of it, where it is an important mineral.
You may think that this means that you need to eliminate it completely, but it is actually an important nutrient for the human body.
Your body uses it to balance blood fluids and maintains blood pressure, and the nerves and muscles need to work.
It is a food preservative because bacteria cannot grow in the presence of large amounts of it.
The human body needs a small amount of sodium to carry out the nervous process.
