Patients with chronic kidney failure should first pay attention to a low-salt and low-fat diet, with daily salt intake less than six grams, and try to eat less salty food such as pickled vegetables and preserved products. Additionally, due to the impaired excretion of potassium and phosphorus in patients with chronic kidney failure, it is necessary to eat less high-phosphorus and high-potassium foods. Common high-phosphorus foods include various marinated meats and other processed foods, and common high-potassium foods include fruits such as bananas, peaches, mangoes, and vegetables like green vegetables and potatoes. At the same time, it is important to maintain a high-quality, low-protein diet. If dialysis treatment has not yet been started, protein intake should be controlled at 0.6 grams per kilogram of body weight per day. If dialysis treatment has already begun, the standards can be appropriately relaxed.
