Patients with kidney cancer can eat mushrooms. They should pay special attention to their diet in daily life, as some foods can harm their body after consumption. It is advisable for kidney cancer patients to eat foods that enhance vitality and avoid spicy and stimulating foods, foods high in iodine, seafood, and also to abstain from drinking alcohol and smoking. Kidney cancer patients generally have less physical activity and poorer digestive functions, so they should primarily consume foods that are light and easy to digest. The diet of kidney cancer patients must ensure nutritional sufficiency and pay attention to a balanced diet, incorporating starchy foods like carrots and peas, as well as foods that enhance the body's anti-cancer abilities, such as mushrooms and shiitake mushrooms.
