Salt is a mineral composed primarily of sodium chloride (NaCl) and is used in food for both preservation and flavor. Sodium ions are needed in small quantities by most living things, as are chlorine ions. Salt is involved in regulating the water content (fluid balance) of the body. Both sodium and chlorine ions are used for electrical signaling ...
[14] [3] If a person has low total body water and low sodium they are typically given fluids. [3] If a person has high total body water (such as due to heart failure or kidney disease) they may be placed on fluid restriction, salt restriction, and treated with a diuretic. [3]

Iodized salt first became available in 1924. By the 1950s, more than 70% of U.S. households used iodized table salt. Bread and some other foods also were fortified with iodine, and iodine deficiency became rare. But diets changed. Processed foods now make up a large part of the American diet, and though they contain a lot of salt, it's not iodized.
