Abstract:
Recent guidelines recommend a restriction of sodium intake below 2,4 g/day (6 g/day of NaCl) in general population to prevent arterial hypertension and cardiovascular disease. Three papers published in 2014 by The New England Journal of Medecine confirm the association between high sodium intake and arterial hypertension. However, marked sodium restriction is also associated with increased mortality. On the other hand, a diet rich in potassium, over 1.5 g/day, is associated with less cardiovascular mortality, and less chronic kidney disease progression.

Sodium Regulation
Sodium ions make up approximately 90% of extracellular cations, with a normal blood plasma concentration of 136–148 mEq/L. A decrease in blood volume and pressure triggers the release of renin from granular cells in the juxtaglomerular complex (JGC), primarily...
