Uses & Benefits
Sodium chloride is an essential nutrient and is used in healthcare to help prevent patients from becoming dehydrated. It is used as a food preservative and as a seasoning to enhance flavor. Sodium chloride is also used in manufacturing to make plastics and other products. It is also used to de-ice roads and sidewalks.
Medical and Health: Hospitals use an intravenous sodium chloride solution to supply water and salt to patients to alleviate dehydration. Sodium chloride is essential to maintain the electrolyte balance of fluids in a person’s body. If levels of electrolytes become too low or too high, a person can become dehydrated or over hydrated, according to U.S. National Library of Medicine.2
Food Flavoring and Preservative: Sodium chloride has been used to flavor and preserve foods for thousands of years. As a preservative, salt helps to prevent spoilage and helps to keep foods like ready-to-eat meats and cheeses safe to eat.3 Salt is also used in fermenting processes for foods like sauerkraut, pickles and kefir.
Manufacturing: Large quantities of sodium chloride are used in industrial manufacturing settings to make a range of products. Plastic, paper, rubber, glass, chlorine, polyester, household bleach, soaps, detergents and dyes are made using sodium chloride.
De-Icing Roads: Roadways and sidewalks are often de-iced by rock salt. Rock salt is the same type of salt used on your dinner table before it is ground into finer crystals.
