Each: Salt

Salt, chemically known as sodium chloride (NaCl), is a mineral compound essential for human health and widely used in food. It is typically obtained through the evaporation of seawater or by mining underground salt deposits, which are then processed and refined.

Manufacturers add salt primarily as a flavor enhancer, bringing out and balancing the tastes in food. It also acts as a preservative, inhibiting the growth of bacteria in cured meats, pickles, and other products. Salt contributes to the texture of foods like bread and cheese, and is found in almost all processed foods, including baked goods, snacks, and ready meals.

Salt (sodium chloride) is considered Generally Recognized As Safe (GRAS) by the U.S. Food and Drug Administration (FDA). High sodium intake is a public health concern because it can contribute to high blood pressure in some individuals. The FDA's Daily Value for sodium is 2,300 milligrams per day. Both the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated salt; JECFA concluded that an Acceptable Daily Intake (ADI) was not specified, meaning that the total daily intake from its use at necessary levels is not considered a health hazard.
