Optimal nutrition for predialysis chronic kidney disease.

Diet potentially plays a major role in the progression and complications of predialysis CKD. Moderate protein consumption along with a diet low in sodium might slow kidney disease progression. Increasing vegetable protein intake might decrease serum phosphorus, uremic toxins, and kidney damage. Because obesity might be an important factor in the increasing prevalence of CKD, dietary strategies targeting obesity might also benefit CKD progression. In those with more advanced CKD, dietary calcium and phosphorus restriction could minimize vascular calcification. Dietary fiber and vitamin D supplementation might also be important to decrease inflammation in CKD. Published by Elsevier Inc.
