Reason 1: Food: fish, shrimp, eggs, milk are the most common, followed by some meat and some plant foods, such as strawberry, cocoa, tomato or garlic and other condiments. In addition, spoilage food is decomposed into polypeptides, and basic polypeptides are histamine release products. Protein food is absorbed in the form of peptone or polypeptide before being thoroughly digested, which can cause urticaria. This is more common in children, and it may also be caused by the different permeability of gastrointestinal mucosa between children and adults. In addition, the addition of food pigments, seasonings, preservatives, natural or synthetic substances in food can also cause urticaria.
