Table Salt

Table salt is a mineral composed primarily of sodium chloride (NaCl). It is mined from underground salt deposits or evaporated from seawater or saltwater lakes. The salt is then purified and often processed to remove impurities and prevent clumping.

Salt is a fundamental flavor enhancer, bringing out the natural tastes in foods. It also acts as a preservative by inhibiting microbial growth, particularly in cured meats and pickled vegetables. Manufacturers use it in a wide variety of processed foods, including baked goods, snacks, canned goods, and condiments.

Sodium chloride is Generally Recognized As Safe (GRAS) by the FDA for use in food. The US National Academies have established an upper intake level for sodium. Excessive sodium intake is linked to increased blood pressure in some individuals. The WHO and EFSA have also evaluated sodium and its health effects, recommending limits on intake. Evidence on the precise impact of sodium on health is complex and ongoing.
