Salt is a naturally occurring mineral that is essential for human health and everyday life. It is made up mainly of sodium and chloride, two elements that help regulate fluid balance, support nerve function, and enable muscles to work properly. Salt is widely used in cooking to enhance the flavor of food and as a preservative to extend the shelf life of many products. It is obtained from underground salt deposits or by evaporating seawater. Although salt is necessary for the body, consuming too much can increase the risk of high blood pressure and heart disease. For this reason, health experts recommend using salt in moderation as part of a balanced diet.
