Can Low Sodium Intake Lead to an Increased Mortality?

It is common knowledge that low sodium intake is beneficial, right? Well, not so fast. There is an interesting article in the Clinical Journal of the American Society of Nephrology which speaks of a possible link to an INCREASE in mortality with low salt intake in one segment of the population. Which patient population is this? The peritoneal dialysis population.

The study was a single center cohort of 305 peritoneal dialysis patients in China who started PD between 2002 and 2007.

This study has limitations, but the conclusion was that low dietary salt intake in this Chinese PD population was an independent risk factor for high overall and cardiovascular mortality.
