When we talk about amounts of sodium, we talk in terms of grams and milligrams. A gram is a unit of weight. There are about 28 grams in 1 ounce. There are 5.5 grams in a teaspoon.
Sodium is essential for good health.
You must have a certain balance of sodium and water in your body fluids and tissues at all times. Too much salt or too much water will upset the balance. In healthy people, excess sodium is eliminated through the kidneys and the correct balance of sodium and water is maintained. In some people, too much sodium leads to or aggravates high blood pressure. Having less sodium in your diet may help you avoid or control high blood pressure.
