Different patients with advanced lung adenocarcinoma have different gastrointestinal function damage and different nutrient deficiencies, therefore, recipes for patients with advanced lung adenocarcinoma need to be formulated in combination with patients’ specific physical conditions. Light and easy-to-digest food with balanced and comprehensive nutrition should be suitable. Lung adenocarcinoma is a type of lung cancer. Patients with advanced lung adenocarcinoma have extensive spreading and metastasis of cancer cells, and their physical condition is poor, with clinical symptoms such as emaciation and anemia. Cancer cells metastasize to digestive organs such as stomach and liver, which can seriously affect the digestive function of patients, resulting in patients not being able to effectively digest and absorb nutrients from food, and lack of nutrients in the body. Recipes for advanced lung adenocarcinoma need to be individualized and customized according to the patient’s physical condition, and each patient’s situation is different, so there is no fixed recipe. As the digestive function of patients with advanced stage of cancer decreases, they should have light and easy-to-digest diet, and in serious cases, they even cannot eat, and if necessary, they need to have intravenous infusion to supplement nutrients. If there is any discomfort, they should consult a doctor in time.
