The History of the Salt Wars.

The "Salt-Blood Pressure Hypothesis" states that an increase in the intake of salt leads to an increased in blood pressure and subsequently increases the risk for cardiovascular events, which has been a point of contention for decades. This article covers the history and some of the key players pertaining to "The Salt Wars" during the first half of the 1900s, both in Europe and in the United States.
