An increased intake of salt and potassium could lead to an increased chronic kidney disease (CKD) progression, according to a study out of the Tulane University in New Orleans. Scientists studied urinary sodium and potassium levels from 3,900 4 CKD patients over a period of three years.
CKD progression was defined as developing End State Renal Disease (ESRD) or experiencing a decreased renal function. Results found that CKD patients with the highest salt levels were 54 percent more likely to experience CKD progression and a 45 percent chance of early death. For those with high potassium levels, 59 percent were more likely to experience CKD progression. The report’s authors suggest the results indicate that a reduction in sodium levels could help slow disease progression, while potassium levels differ by race. You can read more on the study here.
