Most sodium in the diet comes from sodium chloride - better known as table salt. Sodium is a popular food additive, often added to processed food as a flavoring or preservative. Approximately 75% of the sodium Americans consume is added to foods during processing.
Sodium is measured in milligrams (1000 milligrams = 1 gram). There are about 2000 milligrams of sodium in a teaspoon of salt.
Some medications such as antacids are high in sodium. Check with a doctor or pharmacist before taking unprescribed medication.
