Salt Including Sea Salt

Salt, also known as sodium chloride, is a mineral compound essential for life. It is primarily obtained through mining underground deposits or by evaporating seawater. These processes yield crystalline salt, which is then processed for various uses.

Manufacturers add salt to food primarily for flavor enhancement, as it can make foods taste better and balance other flavors. It also acts as a preservative by drawing out moisture, which inhibits the growth of bacteria and molds. Salt is commonly found in a wide range of processed foods, including cured meats, snacks, and baked goods.

Salt is generally recognized as safe (GRAS) by the FDA. It is an essential nutrient needed for proper nerve and muscle function, and to maintain fluid balance. However, consuming too much sodium, primarily from salt, is linked to high blood pressure, a risk factor for heart disease and stroke. The FDA's Daily Value for sodium is 2,300 mg per day. JECFA has evaluated sodium chloride as a food ingredient, recognizing its essential role and considering its use in food.
