Certain foods are often important factors in triggering asthma, including wheat, eggs, milk, meat, tomatoes, chocolate, fresh fish, shrimp, crab, etc., which can cause asthma. Therefore, asthma patients should pay attention to their diet and understand which type or types of food trigger asthma. Once it is found and confirmed that a certain food can indeed trigger an asthma attack, they should try to avoid eating it. But don’t be overly cautious. Foods that do not cause asthma should be eaten as usual. If you avoid everything, the recipes will be monotonous and boring. Over time, it will cause malnutrition and reduce the body’s resistance. It is not a beneficial factor for asthma itself. In terms of food taboos, it should be determined according to personal characteristics. Infants and young children should be wary of foreign proteins, and the elderly should eat less phlegm-producing foods, such as eggs, fatty meats, peanuts, greasy foods, etc. During an asthma attack, you should pay attention to replenishing water and taking light liquids to avoid dehydration or thick phlegm that is difficult to cough up and aggravate breathing difficulties. If Chinese medicine has clearly identified the nature of asthma, it is appropriate to eat foods with opposite properties and flavors. For example, patients with heat asthma should avoid eating hot foods such as mutton, leeks, ginger, peppers and other spicy foods, spinach, bamboo shoots, etc., and eat more cold foods such as celery, pears, water chestnuts, etc. During an asthma attack, you should also eat less flatulent and indigestible foods such as beans, taro, potatoes, etc. to avoid abdominal distension and compression of the chest and aggravating dyspnea.
