What to eat in advanced stage lung cancer? 1. Dietary taboos. Spicy and stimulating food is also one of the dietary contraindications for lung cancer, which includes onion, ginger, garlic, leek, chili, pepper, cinnamon and so on. Therefore, in the daily diet of lung cancer patients, they should put less of these seasonings and eat mainly light food. Lung cancer patients should also not eat barbecue and fried food, because it will also lead to the condition not being controlled in time. Since coughing and producing phlegm is a common symptom of lung cancer patients, in order to alleviate this symptom, patients should not eat oily, sticky and phlegm-producing food either. 2. Add nutrients to diet. When enough calories are supplied, protein nutrition can be supplemented to enhance muscle protein synthesis, and branched-chain amino acids can also provide more heat energy when calories are not supplied enough. There are quite a number of kinds of elemental diets, when applying them, one should start from low concentration, and if taking them orally, one should pay attention to drink slowly, because elemental diets are hypertonic liquids, and citing them too fast is easy to produce abdominal leakage and vomiting. 3.
