Tumor patients, three meals a day can be similar to normal people, but we should increase nutrition appropriately to improve the patient’s physique. According to Nei Jing, “five grains are nourishing, five fruits are helpful, five animals are beneficial, and five dishes are sufficient”. It can be seen that the recipes of tumor patients should be broad, diversified diet, not partial diet, and not excessive avoidance of food to ensure the intake of various nutrients; part of the scientific diet and nutrition plays an important role in the recovery of tumor patients. I. Requirements of modern nutrition 1. Protein food: such as milk, eggs, fish, lean meat, soy products, etc. It should be slightly higher than the normal amount. Insufficient intake can lower the body’s resistance ability and promote the occurrence of tumor. However, if the amount of protein is increased to 2-3 times of the normal amount needed, it may induce tumor patients again. Therefore, the protein intake of tumor patients is 1.5 times of the normal amount as appropriate. That is, 250-300 grams of animal protein, 50-100 grams of soybean products, plus the protein in rice, noodles and vegetables are basically enough, so don’t overdo it. 2, the intake of fat is should be similar to normal people, should not increase, should be mainly vegetable oil, cooking with less frying, frying, smoking and other methods, to steam, stir-fry, stew soup is good, so that food to keep light and delicious. 3, the amount of starchy food intake should be measured for the intake, to achieve a balance, to avoid excessive intake, resulting in obesity, increasing the burden on the body. 4, the fiber in the food can promote the excretory function of the intestine, and can make the intestinal waste out of the body in a timely manner, reducing the time of contact between toxic metabolites and the intestinal wall. Therefore, food should not be too fine, but should be mixed coarse and fine, eat more vegetables. 5.Some inorganic salts such as iron, iodine, selenium, molybdenum, etc., as well as vitamins A, C and E, some of them can prevent the initiation of cell cancer; some can block the effect of cancer factors; some can inhibit the activity of tumor cells; some have the effect of antioxidant, which have positive effects on inhibiting the occurrence and development of tumor cells. Secondly, according to the specific conditions of patients, the dietary therapy of Chinese medicine can often effectively promote appetite, eliminate the side effects brought about by tumor treatment and improve the physical condition of patients. After receiving radiation therapy, patients often have dry mouth and lips, red tongue with less coating, reduced sense of taste and smell, low appetite and other fluid depletion phenomena, so they can eat more sweet and cool foods that nourish Yin and produce fluid, such as lotus root juice, pear juice, water chestnut juice, radish juice, mung bean juice, winter melon soup, rutabaga soup, watermelon, etc.; eat more fish, meat, honey, fresh vegetables and fruits. During chemotherapy, as the drugs kill the tumor cells, it is inevitable that the normal cells will be damaged to a certain extent and produce corresponding toxic side effects, such as decreased immune function, reduced white blood cells, mucosal ulcers in the digestive tract, hair loss and so on. At this time, patients should supplement high protein foods, such as milk, lean meat, animal liver, red dates, adzuki beans, etc. River crab, eel, cuttlefish, beef, etc., help to raise white blood cells. Shiitake mushrooms, mushrooms, fungus and silver fungus can increase immune function. If there is loss of appetite and indigestion, add spleen-healthy and appetizing foods, such as white cinnamon, white lentils, radish, incense , Chen Pi, etc. Mung beans with raw licorice and chemical anticancer drugs used together have the effect of cooling and detoxification and reducing side effects. Post-surgery patients with deficiency of qi and blood can eat more foods such as yam, red dates, cinnamon, walnuts, lotus seeds, river fish, eggs and milk to replenish qi and nourish blood. Third, rich in vitamin A, C, E, minerals food: 1, rich in vitamin A food: carrots, apricots, asparagus, cauliflower, mustard, parsley, lettuce, spinach, green radish, beet leaves, red pepper, sweet potatoes, tomatoes, etc. 2, rich in vitamin C food: fresh hawthorn, aubergine, orange, orange, lemon, kiwi, etc. 3, rich in vitamin E food: vegetable oil, sprouted seeds, wheat germ, etc. 4, rich in molybdenum food: cabbage, cauliflower, etc. 5, rich in selenium food: onions, garlic, mushrooms, etc. 6, rich in iodine food: kelp, nori, sea jelly, etc. 7. Iron-rich foods: green vegetables, beans, grapes, pork liver, beef, dates, brown sugar, etc. Anti-cancer herbal medicine and food Anti-cancer herbal medicine can be divided into the categories of tonic for deficiency and strength, softening and dissolving phlegm, siltation and dispersion, clearing heat and detoxification, etc., among which the first two types of herbal medicine are the main ones. Ginseng, astragalus, royal jelly, angelica, ganoderma lucidum, wolfberry, cistanches (desert ginseng), purple heliotrope (human placenta), heshouwu, lily, asparagus, silver fungus, golden dendrobium (maple dou), cordyceps, asparagus, cranberry, ginkgo, coix seed, kiwi, hawthorn, konjac, kelp, fishy grass, fig, bitter melon, monkey head mushroom, dandelion, etc. are the main ingredients, together with Walnut, longan, jujube, yam, lotus seed, bird’s nest, fish maw, shark’s fin, sea cucumber, oyster, eel, loach, wormwood, turtle, snapper, quail, pigeon, black-bone chicken, chicken, duck, pig liver, pig kidney, pig belly, pig feet, hoof bladder, tenderloin, rock sugar, bee syrup, lotus root powder, water chestnut, sugar cane and various seasonings to make a variety of medicinal dishes such as soup, soup, congee, cold dishes, stir-fry. It has the efficacy of tonic deficiency and strengthening, softening and dispersing hard knots, clearing heat and detoxifying. Patients such as the use of benefits, the use of reasonable, will be beneficial to health. When using medicinal food should pay attention to: 1, according to the patient’s appetite and special requirements, at the same time should be based on the patient’s symptoms, evidence-based food administration. 2, pay attention to dietary contraindications, such as persimmon avoid crab; onion avoid honey; turtle fish avoid amaranth, etc.. When taking tonic products, generally should not eat more radish and radish seeds. 3, food taboos should be adapted to the four seasons of the climate. 4, the diet is appropriate for the person and the disease In food therapy, it is best to choose a wide range of recipes under the guidance of a physician, reasonable identification of the patient both like, and no adverse reactions after eating. V. Common questions 1.What should be noted in diet for cancer prevention? We should adhere to the principles of less food and more meals, less hot and more warm, less hard and more soft, less salt and more light, less sugar and more honey, less wine and more tea (avoid strong tea), less stale and more fresh, less fried and more stewed, less smoked and more fried, avoid smoking and alcohol, avoid eating moldy food, avoid partial food, avoid swallowing, avoid overeating and avoid eating unclean fruits and melons, etc. 2.What are the main foods with anti-cancer effects? It is found that there are many foods with anti-cancer effects, mainly including: ①Foods: corn, soybeans, mung beans, sweet potatoes, barley, etc. ②Vegetables: cabbage, white radish, carrot, eggplant, green pepper, tomato, onion, asparagus, bamboo shoot, garlic, ginger, onion, leek, cabbage, cauliflower, spinach, cilantro, celery, water chestnut, amaranth, potato, taro, yam, cut beans, lentils, etc. ③Fruit and melon: cucumber, bitter melon, winter melon hanging, pumpkin, watermelon, apple, banana, prickly pear, peach, walnut, hawthorn, date, apricot, kiwi, fig, citrus, sea buckthorn, pineapple, strawberry, lotus seed, etc. ④Marine aquatic products: kelp, nori, seaweed, sea cucumber, oyster, shark, loach, turtle, etc. ⑤ Dried mushrooms: silver fungus, black fungus, shiitake mushroom, flat mushroom, monkey head mushroom, etc. ⑥Other: sunflower seeds, tea, honey, milk, yogurt, etc. 3.Will increase nutrition of tumor patients speed up the growth of tumor? The statement of “increased nutrition for tumor patients will accelerate the growth of tumor cells and even increase the chance of recurrence and metastasis” is incorrect and without any scientific basis. Nutritional support for tumor patients is necessary for disease treatment and rehabilitation, and is a guarantee for implementing various treatment measures. Like normal people, tumor patients also need to consume certain nutrition every day, plus the consumption of tumor growth and a lot of consumption caused by surgery, radiotherapy, chemotherapy and other treatment measures, therefore, tumor patients need nutrition, and the nutrition needed is much more than normal people. If no attention is paid to nutritional support and supplementation for tumor patients, it will certainly lead to malnutrition, physical deterioration, inability to tolerate surgery or cause increase of postoperative complications, so that patients cannot complete the treatment for tumor, and affect the treatment effect, so that the clinical cure rate decreases and the mortality rate increases. On the contrary, if attention is paid to nutritional support and supplementation for tumor patients, it can improve the nutritional status of patients’ body while not only will not promote the growth of tumor tissues, but also can inhibit malignant tumor, enhance the immune function of the body, and can effectively cooperate with and withstand various therapeutic measures to ensure the therapeutic effect, improve the quality of life of tumor patients and prolong the survival period. At present, in the international treatment of malignant tumors, nutritional support has become an important adjuvant treatment for surgery, chemotherapy and radiotherapy, so patients do not need to have too many worries. 4.Can cancer patients drink tea? Tea is a necessary product in people’s daily life. Drinking tea is not only a kind of enjoyment, but also very beneficial to human health. Chinese medicine believes that tea has the effect of clearing the head and eyes, eliminating thirst, resolving phlegm, eliminating food, diuretic and detoxification. And modern medical research has proved that drinking tea has the effect of stimulating the senior nerve center, making the spirit excited, active thinking, eliminating fatigue; drinking tea can be diuretic and swelling; drinking tea can also fight the hazards of smoking. For tumor patients, tea contains cancer inhibiting substances, especially green tea, with anti-cancer and improve the role of the body’s immunity. Therefore, tumor patients drink tea properly is certainly beneficial to the body. It is better to drink light tea, not strong tea. It should also be noted that tea contains tannic acid, which can prevent the absorption of vitamins, nutrients and drugs, especially when taking Chinese medicine, it is best not to drink tea; for patients with qi and blood deficiency, it is also not advisable to drink more strong tea. In addition, patients with poor sleep and insomnia should not drink more tea, especially do not drink tea at night. 5.Do tumor patients need to “avoid eating”? What is “hairy food” about? The requirements of “avoiding mouth” and “hairy things” in TCM theory are relatively strict, and there are certain reasons for them. The principle of treatment is “if it is cold, it is hot, if it is hot, it is cold, if it is deficient, it is tonic, if it is real, it is diarrhea”. Therefore, all drugs and foods that do not correspond to the evidence and the needs of the disease are contraindicated. “It is mainly for some allergic diseases such as asthma and urticaria, and most of the “hairy substances” refer to seafood, such as fish, shrimp and crab. To sum up, the “taboo” must be avoided, but it must be justified. If cancer patients have fever, bone steam and hot flashes, hand and foot fever, as well as dry mouth and throat, sleeplessness, night sweating, red tongue with little moss, thin pulse, etc., it is appropriate to eat more watermelon, fruits and cool, thirst-quenching, and eliminate annoying food, avoid eating spicy, greasy things; such as long illness and weakness, especially chemotherapy patients, due to the spleen and stomach Yang trapped, eating tasteless, vomiting and diarrhea, the stomach does not accept, the spleen is unable to rot the grain, then no essence can be part of the Yin deficiency, then should be avoided spicy, hot, fragrant and dry foods that hurt Yin. In some places, it is said that “cancer patients cannot eat chicken because it is a hairy food”, which is not based on science. The current research has not found any case of cancer recurrence due to eating chicken, nor has it been found that eating chicken affects the treatment effect or aggravates the disease. According to Chinese medicine, chicken is slightly warm, sweet and flat, with the function of warming the middle, benefiting the qi, nourishing the essence and adding marrow, and is a good product for treating deficiency, deficiency, stomach dullness, diarrhea and weakness after illness.
