CHLORIDE
Chloride helps with fluid balance, acid-base balance, and nerve cell transmission. It is also a
component of hydrochloric acid, which aids digestion in the stomach. 9
Table salt is 60% chloride, so most chloride in the diet comes from salt. Each teaspoon
of salt contains 3.4 grams of chloride. The chloride AI for adults is 2.3 grams. Therefore,
the chloride requirement can be met with less than a teaspoon of salt each day. Other
dietary sources of chloride include tomatoes, lettuce, olives, celery, rye, whole-grain foods,
and seafood.
Chloride deficiency is rare since most foods containing sodium also provide chloride, and
sodium intake in the American diet is high. 9
