People with bronchitis should avoid overly spicy, stimulating, and greasy foods, such as chili peppers, Sichuan peppercorns, grilled meats, and hot pots. These foods can exacerbate symptoms of coughing and phlegm, hampering the alleviation of the condition. Some cases of bronchitis are caused by allergic factors. If a person is allergic to certain foods, they should avoid those foods. For instance, patients allergic to seafood should not consume it as it could worsen symptoms of coughing and asthma, which is not conducive to the relief of their condition. A light diet should be maintained, with attention to staying warm, avoiding cold exposure, changing unhealthy lifestyle habits, and abstaining from smoking and drinking.
