What is "salt"?

Salt is a mineral compound composed of sodium and chlorine ions. It is one of the most commonly used seasonings and food preservatives worldwide. Salt is essential for human health, playing a crucial role in regulating fluid balance, nerve function, and muscle contraction. In food preparation, salt is used to enhance flavor, balance sweetness, and inhibit the growth of microorganisms, thereby acting as a natural preservative. It is utilized in a wide variety of culinary applications, including cooking, baking, pickling, and curing. While salt is essential in moderate amounts, excessive consumption can contribute to health issues such as hypertension and cardiovascular disease.
