What food does chronic urticaria need to avoid?

Urticaria, commonly known as "rash", is a localized edema reaction caused by the expansion and permeability of skin mucosa. It is characterized by porcelain white or reddish air mass on the skin, and itching or burning sensation. There are many factors that cause the disease, which can be allergic (such as food and drugs), non-allergic (such as cold, heat, wind, humidity and sunlight), and also related to human diseases (such as chronic diseases, intestinal parasites and gallbladder diseases). But the most common reason is eating some allergic food. Therefore, the dietary taboos of this disease play an important role in the onset and prognosis (such as acute to chronic). Taboos for such patients should first know which foods are sensitive to this disease. The foods that cause allergies are mainly animal protein foods, and the most susceptible foods are fish, shrimp, crab, milk, cream products, eggs and so on. Followed by plant foods, such as bamboo shoots, spinach, mushrooms, mushrooms, eggplant, broad beans, cucumbers, garlic, onions, oranges, plums, strawberries, nuts such as chestnuts, ginkgo, walnuts, peanut butter and aromatic seasonings. In addition, some foods can cause some people's allergies, such as wine, chocolate and acrolein (a substance produced when digesting fat and eating fried food), as well as pigments, condiments and preservatives added to foods, natural or synthetic substances in foods such as yeast, salicylic acid and citric acid, and foods added with mint such as mints, mint cigarettes or pastry foods. Chinese medicine believes that the disease is caused by wind (such as acute onset, also refers to allergies, etc. ), blood heat is evil. Most of the above foods can generate wind and blood heat, especially seafood, pig's head, chicken's head, pumpkin, mushrooms, Toona sinensis and other hair products, as well as spicy and greasy foods, which will cause phlegm fire and dissipate qi and blood. Anyone with syndrome differentiation as yang syndrome and heat syndrome should strictly avoid eating. However, not all patients are allergic to these foods, but they should also avoid eating them when they are sick, so as to know which food or which food is most likely to cause disease. For example, some people will get a rash after drinking, so drinking must be strictly prohibited at ordinary times. Patients with urticaria should also distinguish between acute urticaria and chronic urticaria when avoiding food. Acute patients have a rapid onset and severe fever, but they can stop running and recover in a few days to two weeks, that is, they come and go as fast as the wind; Chronic patients repeatedly rise and fall, often delayed for weeks, months or even years. Therefore, if the cause of acute attack is not clear, some foods should be absolutely taboo, especially fish, such as yellow croaker, hairtail, eel, carp, cuttlefish and octopus. Shellfish, such as shrimp, crab, oyster, sea clam, clam, razor clam and turtle; Meat such as chicken, goose, sheep, cattle, pig's head, mushrooms, onions, leeks, peppers, cucumbers, day lilies, pickles, strawberries, ginkgo, chestnuts, peanut butter, wine and seasonings such as vinegar, pepper, pepper and star anise. However, it is difficult to determine the allergenicity of foods eaten by chronic urticaria, because some foods, such as milk, cream, barley, buckwheat, corn, beef, potatoes, broad beans and so on. There is usually a delayed response 24 hours after eating. Therefore, the final decision not to eat is the food exclusion method, that is, only light and infrequent allergic foods are allowed, and then the allergic foods mentioned above are added one by one, and one or more allergic foods are determined by observing the reaction, and then eating is strictly prohibited. However, some foods, that is, products that generate wind and promote blood circulation, are also clear allergic foods, such as hair, seafood and spicy food. Regardless of patients with acute or chronic diseases, we should pay attention to taboos at ordinary times. In addition, all patients with intestinal urticaria should strictly avoid eating rough and indigestible foods, such as frying, frying, smoking, baking, etc., and vegetables containing more cellulose, such as leeks, parsley, bamboo shoots, pickles, etc., otherwise it will easily damage the gastrointestinal mucosa.
