Sodium is essential in the production of hydrochloric acid in the stomach which protects the body from food infections. It is a component of salt; table salt is 40 percent sodium and 60 percent chloride. Sodium has an important role in maintaining the water balance within cells and in the function of both nerve impulses and muscles. Any extra sodium is excreted by the kidneys.
Consuming excess sodium may lead to edema or water retention. Women who consume excess sodium may be at higher risk for developing osteoporosis even if calcium intake is adequate. Sodium intake is one factor involved in the development of high blood pressure, otherwise known as hypertension. Athletes are sometimes concerned about not getting enough sodium to replace what is lost through perspiration.
