Foods with Sodium

Sodium helps to control blood pressure and blood volume. The most common form of sodium is sodium chloride. Most healthy adults require 2,300 milligrams of sodium per day. An excess of sodium in the body can be caused by diet. Hyponatraemia is a condition that occurs when there is not enough sodium in the body. This condition is often caused by drinking too much water. Sodium was isolated for the first time in 1807 by Sir Humphry Davy.
