- Description: An analysis of 13,917 NHANES participants found those in the highest quartile of sodium intake were 21 percent less likely to have chronic kidney disease, and those in the lowest quartile of potassium intake were 44 percent more likely to have it than those in the highest.

Saturday June 15, 2013 (foodconsumer.org) -- A study in Nephrology suggests that high intakes of sodium and potassium may reduce the risk for chronic kidney disease.

Clinicians recommend a diet low in sodium and high in potassium to reduce blood pressure and cardiovascular events. The current study was intended to examine if there is a relationship between dietary intake of sodium and potassium and the risk for chronic kidney disease.

Enrolled in the study were 13,917 men and women from the National Health and Nutrition Examination Survey (2001-2006) whose sodium and potassium intakes were estimated based on their dietary intake of both minerals for a 24-hour period.

For the study, chronic kidney disease was defined as having an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m2 or eGFR ≥60 ml/min/1.73 m2 with albuminuria (>30 mg/g creatinine). 

After adjustment for age, sex, race, body mass index (BMI), type 2 diabetes, high blood pressure, cardiovascular disease and congestive heart failure, participants in the highest quartile of sodium intake were found 21 percent less likely to develop chronic kidney disease, compared with those in the lowest quartile. 

Compared to those in the highest quartile, participants in the lowest quartile of potassium intake were 44 percent more likely to develop chronic kidney disease.

The study concluded "Higher intake of sodium and potassium is associated with lower odds of CKD (chronic kidney disease) among US adults." (reporting by David Liu, PHD)
