After lung nodule surgery, you can eat some food containing dietary fiber and rich in high quality protein. Eat more food rich in dietary fiber, such as celery, cabbage, winter melon and other vegetables, as well as watermelon, bananas, dragon fruit, etc. These foods are relatively rich in dietary fiber, which can promote gastrointestinal peristalsis and prevent constipation. Eating more food rich in high quality protein, such as beef, lamb, soy products, dairy products, etc., will be more beneficial to the recovery of the body after surgery. Lung nodule surgery is a minimally invasive surgery, which is less harmful to the patient’s body. Except for the first day of postoperative fasting to prevent gastroesophageal reflux, the next day you can have a normal diet, and your diet should be light after the surgery.
