Too much sodium and potassium intake may accelerate the progression of kidney disease, a recently published study has shown. Findings from the study are published in the Journal of the American Society of Nephrology.

Researchers from Tulane University analyzed yearly urine samples from 3,939 patients with chronic kidney disease (CKD) to estimate their dietary sodium and potassium intake. They found that high urinary excretion of both sodium and potassium was associated with faster disease progression. Moreover, the study participants were found to have an average intake of 3,700mg of sodium per day, which exceeds the recommended 2,400mg daily limit.

Study findings call for more trials to evaluate the effect of a moderate reduction in sodium and potassium intake on CKD progression in patients with high dietary sodium or potassium intake. The results may affect dietary recommendations for patients with CKD to slow disease the progression.
