In the diet of lung cancer patients, Western medicine does not have the concept of "trigger foods" like Chinese medicine does. According to Western medicine, there are no specific dietary restrictions; the focus is on maintaining a balanced diet as usual, incorporating meat, proteins, vegetables, and fruits to ensure nutritional balance. Generally, lung cancer patients may experience coughing symptoms, so it is advisable to consume a light diet avoiding oily fried foods. Extremely spicy foods can provoke irritative coughing and worsen it, so they should be avoided, along with barbecued and pickled foods, and junk food. Other than that, the diet should be similar to a normal balanced diet. For patients undergoing chemotherapy, a high-protein diet is recommended, preferably consisting of steamed or stewed dishes. These can be combined with traditional Chinese medicinal herbs such as Astragalus, American ginseng, and Dong quai, which are known to boost energy and enhance resistance, thus aiding in dietary therapy to strengthen the patient's immunity.
