Lowering Sodium Intake Slows CKD Progression
Published in Journal of the American Society of Nephrology (JASN)
Expanded Summary
In this multicenter, year-long study, 800 CKD patients were randomized into two groups: one received intensive dietary counseling to limit sodium to <2,000 mg/day; the control group maintained their typical intake (~3,500 mg/day).
Key Findings
- Outcomes tracked:
- Blood pressure, eGFR changes, and hospitalization rates.
- Results:
- The low-sodium group experienced a 5 mmHg drop in systolic BP on average, and had 20% slower eGFR decline.
- Hospitalizations:
- There were 15% fewer hospital visits in the low-sodium group.
Implications
For CKD patients, cutting sodium is a powerful, low-cost intervention. Even modest reductions can improve kidney outcomes and reduce complications.
What This Means for You
Reducing your sodium intake to less than 2,000 mg per day could help protect your kidneys and lower your blood pressure. Small changes in your diet can make a big difference in your health outcomes.
