Salt is a mineral composed primarily of Sodium Chloride (NaCl). It is present in vast quantities in seawater where it is the main mineral constituent. Salt is essential for general and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings to increase appetite and salting is an important method of food preservation.

The World Health Organization recommends that adults should consume less than 5 grams of salt per day.

Salt maintains the pH levels in the blood. In addition, chloride in salt helps to produce hydrochloric acid that promotes digestion.
