Salt, also known as table salt or rock salt (halite), is a crystalline mineral that is composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of ionic salts. It is absolutely essential for animal life, but can be harmful to animals and plants in excess. Salt is one of the oldest, most ubiquitous food seasonings and salting is an important method of food preservation. The taste of salt (saltiness) is one of the basic human tastes.

Salt for human consumption is produced in different forms: unrefined salt (such as sea salt), refined salt (table salt), and iodized salt. It is a crystalline solid, white, pale pink or light gray in color, normally obtained from sea water or rock deposits. Edible rock salts may be slightly grayish in color because of mineral content.

Because of its importance to survival, salt has often been considered a valuable commodity during human history. However, as salt consumption has increased during modern times, scientists have become aware of the health risks associated with high salt intake, including high blood pressure in sensitive individuals. Therefore, some health authorities have recommended limitations of dietary sodium, although others state the risk is minimal for typical western diets.

Famous quotes containing the word salt:

    The indispensable ingredient of any game worth its salt is that the children themselves play it and, if not its sole authors, share in its creation. Watching TV’s ersatz battles is not the same thing at all. Children act out their emotions, they don’t talk them out and they don’t watch them out. Their imagination and their muscles need each other.
    Leontine Young (20th century)

    Well, I know you haven’t had much experience writing and none at all in pictures. But I’ve heard about you. It all sounded like you’re just the man I wanted for a story about the Navy. I don’t want a story just about ships and planes. I want a story about the officers.... I want this story from a pen dipped in salt water not dry martinis. Do you know what I mean?
    Frank Fenton, William Wister Haines, co-scenarist, and John Ford. John Dodge (Ward Bond)

    When the salt sheet broke in a storm of singing
    The voices of all the drowned swam on the wind.
    Dylan Thomas (1914–1953)
