Diabetic kidney disease (DKD), one of the most prevalent microvascular complications of diabetes mellitus, is characterized by increased persistent albuminuria and(or) progressive decrease of glomerular filtration rate. It would eventually develop into end-stage renal disease (ESRD), which leads to severely impaired patient health and quality of life. Malnutrition is relatively common in DKD and can significantly increase the risk of all-cause mortality in patients with diabetes. Medical nutrition therapy (MNT) can delay the progression to ESRD, and prevent malnutrition or protein-energy wasting. The Chinese Society of Endocrinology convened a task-force to develop evidence-based expert consensus to provide clear guidance for implementation of individualized MNT care to improve clinical outcomes of patient with DKD.
