1 Sodium plays a large role in fluid balance, with different variations of sodium determining the shift of water by osmosis from one area of the body to another.  Along with chloride and bicarbonate, sodium is important for the proper regulation of the acid-base balance of the body.
Sodium is an element that the body needs to work properly. Salt contains sodium. The body uses sodium to control blood pressure and blood volume. Your body also needs sodium for your muscles and nerves to work properly. Sodium occurs naturally in most foods. The most common form of sodium is sodium chloride, which is table salt. Milk, beets, and celery also naturally contain sodium.
