Lung cancer is a very common cancer, ranking second in the mortality rate of malignant tumors in China. Generally, the systemic symptoms of lung cancer are not obvious. In the early stage, there may be symptoms like tuberculosis such as cough, shortness of breath and blood in sputum. In the late stage, patients may have fever, emaciation, fatigue and even cachexia.

The digestive system function of lung cancer patients in the early and middle stages is sound. After clinical diagnosis, we should take the time to supplement the body with nutrition, so as to improve physical fitness, enhance resistance and prevent or delay the emergence of cachexia. If the nutrients are fully charged before clinical treatment, patients with better physical condition will have stronger tolerance to chemotherapy and radiotherapy, and the treatment effect will be better; Similarly, patients with better physical condition are more likely to receive surgical treatment and recover faster than patients with poor nutritional status. Therefore, patients with early and middle stage lung cancer should be supplemented with various nutrients as soon as their digestion and absorption capacity permit, such as high-quality protein, carbohydrates, fats, inorganic salts and multivitamins.

For the symptoms of lung cancer patients, such as cough and hemoptysis, there are many prescriptions and recipes for nourishing yin and moistening lung, relieving cough and stopping bleeding and astringing in Chinese medicine, such as nourishing yin and moistening lung and foods such as almond jellyfish, lily, water chestnut, etc., while lotus root nodes, lotus seeds, persimmons, pears, yams, lilies, white fungus, etc. all have the functions of relieving cough, astringing and stopping bleeding. According to folk prescriptions, patients with lung cancer can also eat foods that nourish yin, such as clams, tortoise plastron, tortoise meat and glutinous rice.

Compared with digestive tract tumors, the diet of lung cancer patients should be easier to solve. In addition to the above-mentioned nourishing foods of traditional Chinese medicine, lung cancer patients should choose milk, eggs, lean meat, animal liver, bean products, fresh vegetables and fruits and so on. Can try to increase the patient's food intake and frequency. Attention should be paid to: patients with lung cancer should avoid greasy food, spicy food and irritating food such as cigarettes and alcohol.

II. Dietary therapy for lung cancer

(1) Strengthen nutrition: When patients with lung cancer have no difficulty swallowing, they should choose their food freely. Under the condition of not affecting the treatment, they should eat more protein and carbohydrate-rich foods, such as lean meat, chicken, duck, rabbit, fish, shrimp, bean products and various cereals, which generally do not limit their food intake, so as to ensure good nutrition and create opportunities for surgery.

if the nutritional status is poor, it is difficult to tolerate the trauma of operation, and the postoperative healing is slow and easy to be infected, which is extremely unfavorable for surgical rehabilitation. This requires improving the quality of diet before operation.

(2) elemental diet: lung cancer patients should be supplemented with elemental diet in addition to three meals a day half a month before the operation. Elemental diet contains all kinds of nutrients necessary for human body. Because the nutrients are complete, it can meet the needs of the body. It can be absorbed in the upper part of the small intestine without digestion, and can be taken orally or by tube feeding. The essential diet can not only supplement the nutrition of protein, but also promote the synthesis of muscle protein when the heat supply is sufficient. When the heat supply is insufficient, branched-chain amino acids can also provide more heat energy.

There are many kinds of essential diet, which can be fed orally or by tube. When applied, it should start from a low concentration, which is generally 5% and gradually increase. If there is no diarrhea or vomiting, it can be gradually increased to 1% to 2%. If you take it orally, you should pay attention to slow drinking. If you drink it too fast, because the essential diet is hypertonic, it is easy to produce diarrhea and vomiting. Pay attention to the appropriate temperature to prevent diarrhea caused by too cold. If you take 1 grams of essential diet every day, you can increase calories by 4 kilocalories and protein by 16 grams. At the same time, it increases the immunity of the body and can tolerate surgery.

(3) postoperative diet: after the operation, the diet should be determined according to the condition. Some patients can eat on the second day after the operation, but the food should be light, soft and easy to digest and absorb, because surgical trauma will cause dysfunction of the digestive system, so don't rush to seek success in food selection and tonic. We should start from the simplest, if there is no adverse reaction in gastrointestinal tract, then transition to semi-liquid food and general food. Within a week after the operation, in addition to eating clean and semi-fluid, we should also supplement the essential diet to supplement the nutrition in the body. When you can eat normally, cancel the elemental diet. Eat more fresh vegetables and fruits, such as green vegetables, yellow vegetables, red vegetables, mushrooms, black fungus, asparagus, lemons, red dates, etc., before and after the operation, because fruits and vegetables are rich in vitamin C, which is an anticancer substance and can block the generation of cancer cells.

don't eat or eat less irritating food, including fried food. You can often eat garlic, which contains anticancer substances. Don't smoke or drink. Developing good living habits and eating habits, regular physical examination, timely diagnosis and treatment can prolong life.
