Salt is composed of two minerals sodium (Na) and chloride (Cl). Table salt (NaCl) contains about 40% sodium and 60% chloride. One teaspoon of salt contains about 2,300 mg of sodium. As much as we are told to limit sodium in our diets, we all need some sodium for good health. However, the average American diet contains about three times more sodium than is healthy, which leads to high blood pressure and other health issues.
