Appropriate nutrition is vital for patients with CKD at all stages. Numerous studies indicate that diet rich in fruits, vegetables, fish, cereals, whole grains, fibers and polyunsaturated fatty acids but low in saturated fatty acids is beneficial for CKD patients. Also, a very-low protein diet supplemented with amino acids and keto acids (s-VLPD) was found to be safe and advantageous for patients with chronic kidney disease, especially at stages 4-5, due to the fact that it corrects proteinuria, blood pressure and hemoglobin and therefore it may prolong not only the dialysis-free period but also the survival. However, switching diets should be carefully consulted with a nephrologist and monitored by a dietician to avoid nutritional errors which can accelerate kidney function deterioration.
