Carrots Carrots are rich in vitamin A source (carotene) and are nutrients of the "anti-cancer system". 2. Fungi include Lentinus edodes, mushrooms, mushrooms and Hericium erinaceus. , mainly containing polysaccharides. Scientific experiments have proved that the polysaccharide can regulate the immune function of human "anti-cancer system", thus inhibiting the growth of cancer and relieving the symptoms of cancer patients. 3, high-fat fish research found that eating high-fat fish at least once a week can reduce the risk of kidney cancer by 74%. High-fat fish mainly include salmon, herring, sardines and herring, which live in the deep sea. The vitamin D content of high-fat fish is 5 times higher, and the omega -3 fatty acid content of deep-sea fish oil is about 20 times higher. 4. Bananas People who eat 6 to 8 bananas a day are nearly half less likely to develop kidney cancer than those who don't eat them at all. Banana and other fruits and vegetables contain a large number of special antioxidant compounds called phenolic plastics, which have a strong inhibitory effect on tumor formation, so it is considered that this kind of food has anti-cancer effect. Tomatoes often eat fruits and vegetables rich in lycopene, which helps to reduce the risk of kidney cancer. Lycopene can be obtained not only by eating tomatoes, but also by using tomato products such as tomato sauce, tomato juice and tomato sauce. The results show that there is an important correlation between lycopene and the decrease of the incidence of renal cancer. Compared with women who consume the least lycopene, women who consume the most lycopene (equivalent to eating four tomatoes a day) have a 45% lower risk of kidney cancer. What should the postoperative diet of patients with renal cancer pay attention to? 1. Patients should drink proper amount of alkaline water to replenish water, promote the dissolution and excretion of urate and prevent hyperuricemia. 2. Patients should eat more foods containing folic acid, such as broccoli, cauliflower, cabbage and spinach. Rich folic acid can increase the content of methionine in blood and has a strong anti-cancer effect. 3. Patients should eat more foods containing vitamin C, such as grapefruit, citrus and lemon. Vitamin C can reduce the damage of free radicals in the body to normal cell genes and prevent cell canceration. 4. Patients should take protein in moderation, and the daily intake of protein is 0.6 kg per kg of body weight, such as egg white, dairy products, fish and poultry. Protein intake should be accompanied by enough calories to maintain the normal weight of patients. Patients should eat more whole grains. Gleditsia sinensis, which is rich in whole grains, can alleviate the activity of carcinogens in the intestine, and rich fiber can prevent cancer recurrence. 6. After kidney cancer surgery, some iron agents can be added appropriately. Renal cell carcinoma can be eaten with ferrous sulfate, animal liver and spinach. The temperature of food is preferably 40~50. Alcohol and tobacco, beef and mutton, coffee, spicy food, fried, crab, garlic, raw onion, coriander, dog meat, spiced aniseed and all hair products are prohibited. 7. After renal cell carcinoma surgery, due to the injury of vital qi, kidney qi, qi and blood, it is advisable to replenish qi and nourish blood. Patients with renal cancer eat foods rich in protein, such as milk, soybean milk, mashed potatoes, mung bean paste, spinach paste and fish soup. And they can also stir-fry meat with Lycium barbarum. But pay attention to the food should not eat too much too full. 8. High-quality protein is good for human health, but it should be eaten in moderation for patients after kidney cancer surgery. For example, the daily intake of milk, carp and adults is about 60g, and it is mainly high in biological protein. Patients with non-diabetic renal cell carcinoma should appropriately increase their sugar intake to ensure adequate energy and reduce negative balance. 9. It is best to refine the diet of patients with kidney cancer or renal insufficiency. In principle, in addition to the low-protein diet, we should eat more starch to ensure enough calories, and determine the intake of water and salt according to the edema. But we should also remember the principle of "five lows and one high diet": low salt, low fat, low protein, low phosphorus, low potassium and high vitamins. 10, renal cell carcinoma patients gradually return to normal diet after operation, that is, three meals a day, which takes at least 6~8 months. Therefore, it is the dietary principle for renal cell carcinoma patients to leave the hospital after operation and eat less and more meals. Eat 5~8 times a day, and take 75 ~ 100g food each time. At first, the quantity was small and the number of times was large, and then the quantity became less and less. From liquid, semi-liquid to soft food.
