Patients with lung cancer should not let down their guard even after surgical resection, because lung cancer can easily recur and metastasize after surgery. Therefore, in addition to long-term consolidation treatment, post-surgical lung cancer patients also need good post-surgical dietary care. Lung cancer is one of the top three cancers that endanger human health. After lung cancer lobe removal surgery, lung cancer patients are very weak, so they must pay attention to nutritional supplements in their diet at this time, especially for such malignant tumors as lung cancer, and even more attention should be paid after surgery. Because surgery for lung cancer is an invasive treatment, it cannot avoid causing harm to the patient’s body during the treatment process, resulting in a decrease in immunity and weakness. After lung cancer surgery, patients should eat light and easily digestible food after they can eat, but to ensure sufficient nutrition, they can eat more vegetables and fruits and other foods. What is good to eat after lung cancer surgery? 1.The proportion of fruits and vegetables accounts for 1/4 of daily diet Fruits and vegetables contain many vitamins, which are also essential nutrients for human body. Some vitamins also have strong oxidizing properties, which can help detoxify the body, promote metabolism, timely remove harmful free radicals from cancer patients’ bodies, avoid premature aging of normal cells and prevent sudden changes in the disease. The consumption of fruits and vegetables after lung cancer surgery should account for 1/4 of daily diet, and which fruits and vegetables to eat should be decided according to the patient’s taste. On the third day after lung cancer surgery, you can have semi-liquid diet, about 500 ml each time, five to six times a day. After four to five days, you can resume normal diet and eat more light and easily digestible foods, such as fish and shrimp, to help wound healing and physical recovery. 2.Supplementation of selenium With the development of medical technology and the popularization of health knowledge, selenium is gradually applied in the field of auxiliary anti-cancer. It has strong oxidizing and anti-cancer effects. Proper selenium supplementation can not only reduce the incidence of cancer, but also help a lot in cancer treatment. 3.Protein-rich food can be given priority to protein food. Protein is the main component of human body, which is the main nutrition for constituting antibodies, hormones, enzymes and various tissues and organs. The growth and spread of cancer cells will devour a lot of protein, and the protein in patients’ body is even more lacking after lung cancer surgery, so they should eat more fish, poultry, milk, eggs, animal liver and other foods rich in high quality protein. Pork, beef and mutton among lean meat are also rich in protein, but the muscle fiber is coarse and hard, and the water in meat is not enough, so it is relatively difficult to digest, so it can be eaten in moderation. Another point to note is that after surgery, many patients will overly abstain from some things in order to recover better. The recurrence and metastasis of tumor patients have nothing to do with whether to abstain from eating or not, as long as they want to eat, they can eat and be comfortable to eat. Patients with advanced lung cancer often have symptoms such as fever, emaciation and weakness. At this time, the diet should be diversified, multi-course, not partial, and avoid eating only one kind of food. When cooking dishes, more efforts should be made in terms of color, fragrance and taste according to patients’ taste. If you have nausea during meals, you can drink some ginger juice before the meal. The most important thing is to avoid being too hungry and too full, and to avoid eating greasy food, lest the appetite will be lost, causing the patient to be more lethargic and weak.
