Although the causes of urticaria are complex, food factors are currently thought to account for a large part of the onset. Acute urticaria, in particular, is often directly related to food. The emphasis in urticaria is on a restricted diet, but it should be targeted and reasonably restricted. For acute urticaria, if it is not caused by infection or medication, the first thing you should do is avoid stimulating allergy-prone foods, spicy, seafood, dairy, eggs, etc. Be sure to review carefully if there are foods and drinks you don’t usually eat and drink, including vegetables and fruits. In particular, some spices and preservatives are not ignored, because these substances are not easy to attract attention, the actual allergy to these substances is not uncommon. 1, it is advisable to enter a light diet, more rest, do not get tired, moderate exercise. Eat more fresh fruits and vegetables rich in vitamins, more alkaline foods such as: grapes, green tea, kelp, tomatoes, sesame seeds, cucumbers, carrots, bananas, apples, oranges, radishes, green beans, nuts, etc.; 2. Avoid eating spicy and fishy hairy substances. In the absence of possible triggers, try to avoid fish, shrimp, crab and stimulating food. Such as shrimp and crab, oyster, sea clam, snapper, scallop, eel, pork, rooster, beef and mutton, mushrooms, bamboo shoots, mushrooms, etc., because these foods are easy to produce wind and heat, which can catalyze the production of the disease. Chili, pepper, cinnamon, onion, curry, fennel, tobacco and alcohol, etc. Because these foods can help heat and blood, inducing the occurrence of the disease; sometimes can also directly become allergens, producing allergic reactions; 3, avoid eating fried fatty food. Such as a variety of fried, fried, smoked and cured meat products, animal offal, cream cakes, chocolate, etc., because these foods are easy to produce phlegm fire or gather moisture and heat, so that moisture and heat contained in the skin and induce the disease; 4, for chronic urticaria diet restrictions more cautious. Because the causes of chronic urticaria are more complex than acute, food factors are not very major. Some dried fruits, such as walnuts, beans, peanut butter, chocolate, coffee, lemon drinks, etc. are not uncommon. For patients with urticaria, especially chronic ones, one must carefully, patiently search for the most likely cause. In short, acute urticaria restriction of diet is the main, chronic urticaria other factors are more common, it is best not to overly, blindly restrict the diet. Allergen testing should be done when conditions permit, and dietary modification should be guided by the results.
