The KDOQI clinical practice guideline (CPG) for nutrition in chronic kidney disease (CKD) was updated after 20 years from the previous guideline. During this period, the severity of CKD was defined by eGFR and albuminuria by KDIGO. Main risk factors of CKD such as hypertension, hyperlipidemia, obesity, metabolic syndrome, and diabetes mellitus (DM) are closely related to lifestyle. Dietary modification is important to prevent and retard the progression of CKD. In this review, I will focus on salt (sodium) restriction. Members of the International Society of Renal Nutrition and Metabolism (ISRNM) reviewed the draft of the KDOQI CPG. ISRNM is an international scientific society that has been operated with members of both subspecialties. ISRNM proposed previously the medical term of protein- energy wasting (PEW) which is a keyword to renal nutrition. The prevalence of PEW is high among dialysis patients. The success of dietary therapy is partly depending on adherence to the diet. It has to be palatable, otherwise eating habits will not change. To prevent the development of PEW, regular consultation with the expert dietitian is required in particular for salt and protein restriction. Our cluster-randomized trial showed that the intervention of dietician was effective to retard the progression of stage 3 CKD patients. In this review, the tips of salt restriction and Japanese kidney-friendly recipes were introduced. Due to the lack of randomized controlled trials, nutritional management in CKD is inevitably relies on expert opinion. In this regard, well-designed observational studies are needed. Also, we have to pay attention that too strict salt restriction may aggravate quality of life (QOL) and may induce PEW. Reference 1. Ikizler TA, Burrowes JD, Byham-Gray LD, et al.
