Alkaline diet and long term preservation of renal function in stage 5 CKD

Kidneys produce bicarbonate ions that neutralize acids in the blood. Patients suffering from Chronic Kidney Disease (CKD) often present metabolic acidosis, as the kidney can no longer neutralize the acid load. Alkaline diet based on fruits, vegetables and mostly plant protein may have a positive effect on long-term preservation of the renal function in patients with stage 4-5 CKD while maintaining the nutritional status.
