We are constantly warned of the dangers of eating too much salt. Some people, however, face a greater danger from eating too little salt—even as they try to eat less of it.
The Importance of Salt
Salt has been used since ancient times for food preservation and seasoning. Ancient people often obtained salt by boiling spring water rich in minerals. In fact, some of the world’s oldest known salt mines can be traced back to around 6000 B.C.The term “salary” originates from the Latin word “salarium,” which referred to the allowance given to Roman soldiers to purchase salt, reflecting the importance of salt in daily life. Throughout human history, certain wars and the rise and fall of cities have been closely linked to salt.
