For patients with acute urticaria, dietary treatment should pay attention to spicy and irritating foods as well as seafood such as fish and shrimp. There are also high-protein foods like silkworm pupae, which should be avoided, and smoking and drinking must also be avoided. Because of the above, these are generally the more common causes of hives in patients. However, because each patient’s constitution is different, the causes of allergies that cause hives to occur in patients vary from person to person. If some hives patients experience hives even after eating ordinary fruits and vegetables, it is best to check the allergen so that you can usually do effective avoidance. The vast majority of people with hives have no problem eating ordinary fruits and vegetables and meat during the acute phase of hives.
