Did low-sodium diet trigger leg cramps?

A. Sodium has long been vilified by public health officials. An eight-year study in the Journal of the American Medical Association (May 4, 2011) showed, however, that people consuming the least sodium in their diets had the highest mortality.

Another study found that low intake of sodium was linked to an increase in stress hormones (adrenaline, renin and aldosterone), which might have a negative impact on cardiovascular health (American Journal of Hypertension, January 2012).

Those who are salt-sensitive or have heart disease may indeed benefit from a low-salt diet. Someone like you, though, may discover that too little sodium can sometimes have negative consequences. Many readers report that pickle juice or yellow mustard, both high in sodium, can help relieve muscle cramps.
