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.
