Patients with lung cancer can consume food in general. Patients often do not have appetite, so they can improve their appetite with traditional Chinese medicine, such as ginsenoside, which can improve patients’ appetite, enhance their immunity, induce differentiation of tumor cells, and make cancer cells change their ways. Therefore, lung cancer patients can eat more easily digestible porridge, such as silver fungus porridge and millet porridge, and high-quality protein is also indispensable. Lung cancer patients are generally in poor physical condition, so they should not neglect the daily intake of high-quality protein, such as milk, eggs, lean meat, fish, soy products, etc. They can also eat more vegetables and fruits, which are rich in vitamins, and lung cancer patients can eat more tomatoes, loofahs, green peppers, grapes, strawberries, etc. For lung cancer patients, the current medical profession promotes the diet of eating less and more meals, with each meal being eight minutes full, which is most helpful to the recovery of health.
