摘要

The recommendations on nutrition in chronic kidney disease (CKD) have greatly changed in recent years, also in the guidelines. Patients with CKD have a high cardiovascular mortality and dietary patterns to prevent cardiovascular disease are also recommended for CKD. Potassium and phosphate from plant-based, low-processed foods have a much lower bioavailability than from ultra-processed food sources (UPF). For patients at risk of hyperkalemia, diets rich in bioavailable potassium should be limited. Dietary fiber reduces systemic inflammation, stabilizes the intestinal barrier and accelerates the gastrointestinal transit time. Patients in higher CKD stages are at higher risk of malnutrition and sarcopenia; both are increased by protein-restricted diets. The Kidney Disease: Improving Global Outcomes (KDIGO) 2024 CKD management guideline therefore recommends 0.8 g protein/kg body weight per day for most CKD patients.
