Patients with kidney cancer should pay attention to maintaining a balanced intake of nutrients and avoid consuming spicy and stimulating foods, as well as foods that may increase the metabolic burden on the kidneys. It is advisable to minimize or avoid consumption of lamb. Patients should also avoid drinking alcohol, especially strong spirits, and refrain from smoking and eating pickled items or leftover meals, as these may aggravate the cancer condition. It is recommended to eat garlic and consume fruits and vegetables like cucumbers, pears, and peaches, such as apples, pears, and apricots, to increase intake of vitamins and fiber. The daily diet should be light, with an emphasis on high protein intake, including more fish in the diet.
