What food bronchial asthma patients eat is a question with much consideration. Foods that bronchial asthma patients should avoid mainly fall into two categories: First is allergens. If a patient has previously had an allergy to certain foods, is suspected to be allergic, or has family members who are allergic to a particular food, then they should avoid eating it. Also, common allergens like small fish, shrimp, and seafood should be avoided, especially during asthma attacks. The second category is spicy and irritating foods, which should also be avoided. Therefore, the primary focus should be on eating light, easily digestible foods, and sticking to foods that are commonly eaten, avoiding those that have not been tried before. Moreover, if a food is known to potentially cause allergies after medication, it should not be consumed. (Please use medication under the guidance of a professional physician, and do not self-medicate.)
