Barbecue is not allowed during the treatment of tuberculosis because during the treatment of tuberculosis, spicy, stimulating and greasy food should be avoided and food rich in high quality protein, vitamins and easy to digest should be the mainstay. Eating barbecued or fried food can easily stimulate the throat and bronchial tubes of patients, induce coughing and can lead to aggravation of their existing cough, and in a few patients, their violent coughing can lead to hemoptysis. In addition, foods such as barbecue can easily cause indigestion and stimulate the gastrointestinal tract, causing gastrointestinal discomfort. In addition, barbecue itself is also unhealthy food, which contains a variety of carcinogenic substances, and should be avoided at this time.
