Kidney failure can eat vegetables containing potassium and low phosphorus, such as broccoli, shiitake mushrooms, zucchini and so on. Patients with renal failure are prone to electrolyte metabolism disorders, such as hyperkalemia and hyperphosphatemia, which increase the risk of arrhythmia, skin itching, and vascular calcification because of reduced excretory function, so they should reduce the intake of potassium-containing and phosphorus-containing foods in their life. For example, 100g of broccoli contains 72mg of phosphorus and 17mg of potassium; 100g of shiitake mushroom contains 53mg of phosphorus and 20mg of potassium; 100g of zucchini contains 17mg of phosphorus and 92mg of potassium; the above foods contain relatively less potassium and phosphorus and can be consumed in moderation. Another 100g of portobello mushroom contains 1655mg of phosphorus and 3106mg of potassium; 100g of seaweed contains 350mg of phosphorus and 1796mg of potassium, which should be avoided. It is recommended that patients with renal failure should go to regular hospitals in time and follow the doctor’s instructions for standardized treatment and reasonable diet.
