Salt is a crystalline mineral made of two elements, sodium (Na) and chlorine (Cl).
Sodium and chlorine are essential for your body, as they help your brain and nerves send electrical impulses.
Most of the world’s salt is harvested from salt mines or by evaporating seawater and other mineral-rich waters.
Salt has various purposes, the most common being to flavor foods. Salt is also used as a food preservative, as bacteria have trouble growing in a salt-rich environment.
The reason that salt is often deemed unhealthy in large amounts is that it can raise blood pressure.
