Patients suffering from emphysema can eat more of the following foods: 1. Eat more apples, pomegranates, oranges, strawberries, kiwis, cherries, tomatoes and other fruits, because these fruits are rich in vitamin C, which is good for improving the immunity of patients and increasing their ability to fight diseases. 2. The pear has the function of clearing and moistening the lung, which is suitable for emphysema patients who often feel dry mouth and bitterness. 4. lean meat, eggs and milk, because meat, eggs and milk are rich in high-quality protein, which can be easily digested and absorbed by the body, which can not only supplement nutrition but also improve the patient’s resistance. Patients with emphysema must quit smoking and drinking, and should not eat spicy, stimulating and fire-prone foods in their diet. They should usually drink warm light salt water to help dilute the phlegm.
