Some cancer patients have too many "rules", one can't eat this and the other can't eat it; And some patients dare to eat what they can eat. As everyone knows, the above two attitudes are unfavorable and even harmful to the treatment and rehabilitation of patients. Here, the author introduces the reasonable diet of lung cancer patients: 1, and walks out of the misunderstanding of diet. Contraindications of cancer patients should vary from syndrome to syndrome, from person to person and from treatment methods. Don't stipulate what can and can't be eaten in general, and don't be too strict with taboos, or even be mysterious. To eat more foods rich in protein, some people mistakenly think that cancer cells are better at absorbing nutrients than normal cells. If they eat more protein, it will be good for cancer cells. However, if nutrition is insufficient, the immune function of human body will be at a low level, and the anti-cancer ability will be further weakened, which is conducive to the development of cancer cells and the decline of quality of life. For example, chemotherapy patients do not have a certain supply of protein, and it is difficult to recover white blood cells and hemoglobin. Therefore, we think that the taboo should not be too strict and the diet should not be too narrow. We should pay attention to the diet of high protein and vitamins to make up for the excessive consumption of tumors and improve the immune function, anti-cancer ability and quality of life of human body. 2. Choose a reasonable diet. Avoid eating foods containing carcinogens, such as pickled vegetables and meat containing nitrite, moldy, smoked and stale foods containing food additives, and crops with serious pesticide pollution. Always eat foods that are conducive to detoxification, such as mung bean soup (porridge), red bean soup, melon, watermelon and so on. You can also choose foods with anti-tumor effects, such as shiitake mushrooms, shiitake mushrooms, Ganoderma lucidum, Cordyceps sinensis, auricularia auricula, tremella, etc. Lettuce, shepherd's purse, day lily, towel gourd and pumpkin in vegetables; Apricot, pear, bayberry, kiwi, loquat and pomegranate in fruits; Lotus root, lily, water chestnut, garlic, radish, asparagus, carrot, tea, etc. Chicken, duck, goose, crucian carp, turtle, sea cucumber, silkworm chrysalis, royal jelly and other animals. 3. Try to increase your appetite. The main psychological reactions of patients with advanced lung cancer are anxiety and depression, which will lead to different degrees of loss of appetite. Therefore, first of all, we should do a good job in psychological care, help patients build up confidence, relieve their ideological worries, provide a quiet and tidy dining environment, and try to leave the hospital bed and sit at the table. You can drink a small amount of alcohol (low alcohol content) before meals, or give Chinese medicine an appetite and strengthen the spleen. Give fruit and the like after meals. Second, we should pay attention to diversification, a variety of recipes, avoid monotony, balance nutrition, pay attention to the diet structure, and avoid eating one food day after day. Pay attention to the sensory characteristics of food. Pay more attention to color, fragrance and taste. Third, if you feel sick when eating, drop a few drops of ginger juice into your mouth when eating; Or acupuncture Neiguan, or injection of metoclopramide at Neiguan point, or taking traditional Chinese medicine for lowering adverse qi and stopping vomiting. Fourth, keep the stool unobstructed. Constipation, obstruction of fu-organs, disharmony between stomach and qi, don't think about diet. Eat more crude fiber foods such as asparagus, celery and bananas, and keep laxatives or traditional Chinese medicine enema when necessary. Fifth, be careful not to be too hungry and full, and avoid eating products that are sticky and easy to produce waste gas, so as to avoid loss of appetite. 4, according to the nature of food and taste function, dialectical feeding. Food, like medicine, has four flavors, so the diet should be chosen according to the cold and hot conditions. The cold is hot, the hot is cold, and the weak supplements it. In fact, it is diarrhea. It is also necessary to distinguish between clearing lung yin deficiency and clearing lung yang deficiency. Yin deficiency should be supplemented, and yang deficiency should be warmed. According to clinical manifestations, lung cancer patients can be divided into yin deficiency and heat toxicity, phlegm-dampness blocking lung, qi stagnation and blood stasis, and deficiency of both qi and yin. Yin deficiency and heat toxin type: clinical manifestations are low fever, night sweats, dry cough with little phlegm, or blood in sputum, dysphoria, chest pain, shortness of breath, thready pulse, red tongue and thin yellow fur. Such patients should not eat warm products, such as velvet antler, mutton, dog meat, shrimp and spicy and fragrant things. You should eat houttuynia cordata, day lily, duck, lotus root, reed rhizome, asparagus, lily, banana, sugarcane, American ginseng, lotus seed, fungus, turtle and so on. Phlegm-dampness blocking lung type: clinical manifestations are cough and expectoration, chest pain and shortness of breath, mental fatigue, slippery pulse, dark or fat tongue, white and greasy fur. This kind of patients should not eat sticky, spicy and dry things, but should eat foods with the functions of strengthening the spleen, resolving phlegm, detoxifying and clearing the lung, such as rice kernels, lotus seeds, radishes, corn and long beans. Qi stagnation and blood stasis type: The clinical manifestations are unsmooth cough, chest tightness, chest pain, constipation, dry mouth, bloody sputum, thready pulse, red tongue or ecchymosis, and thin yellow fur. Such patients should eat more foods that can regulate qi and relieve depression, promote blood circulation and detoxify, such as eggplant, fungus, Nostoc flagelliforme, celery and water chestnut. Deficiency of both qi and yin: clinical manifestations are fatigue, shortness of breath, laziness in speaking, dry mouth, constipation, cough with little phlegm, red tongue, or fat body with thin white or little fur. Such patients should eat more foods with the function of benefiting qi and nourishing yin, such as grapes, pears, mulberries, rice kernels, lobster sauce, American ginseng, yam, soft-shelled turtle and snakehead. Clinically, corresponding symptomatic foods are given according to different symptoms. If you cough with too much phlegm and the phlegm is thick and yellow, boil Sydney, stew honey with Fritillaria, and stir-fry asparagus with Houttuynia cordata clear liquid. Cough thin phlegm, can take Stemona chicken soup, almond fried tofu; People with blood stasis and pain in lung cancer can eat peach kernel porridge, asparagus stew with three shreds, pumpkin slices with soy sauce and Trichosanthes kirilowii cake. Lung cancer patients with cough and hemoptysis can take bird's nest soup and lily Tianqi stewed rabbit meat; People with lung cancer fatigue, cough and asthma, spontaneous sweating and night sweats can take whole duck stewed with Cordyceps sinensis and fried shredded chicken with American ginseng; For patients with lung cancer pleural effusion, you can use red dates and longan to steam ducks and mushrooms and stir-fry snails. In short, a reasonable diet is of positive significance for cancer patients to better receive anti-tumor treatment, improve human immune function, improve quality of life, prolong life and recover from diseases.
