Patients with urticaria can adjust their diet appropriately, choosing light, easily digestible foods rich in vitamins, which can help relieve symptoms. It is recommended to eat more fresh fruits and vegetables and high-quality protein, while avoiding foods that may trigger allergies.

1. Eat more fresh fruits and vegetables, such as spinach and apples. They are rich in vitamins and antioxidants, which can help reduce inflammation in the body and are beneficial for skin recovery.

2. Choose high-quality protein: such as chicken, fish, and soy products. These foods are easy to digest and can provide the body with the necessary nutrients to support the normal functioning of the immune system.
3. Pay attention to hydration and light cooking: Drink enough water every day to promote metabolism. When cooking, try to use steaming or boiling methods, and use less fried and spicy seasonings to reduce skin irritation.
4. Be aware of and avoid suspected allergenic foods: such as seafood, nuts, and certain food additives. If you find that your symptoms worsen after eating them, try to avoid them temporarily and observe the situation.
In your daily diet, maintain regular mealtimes and avoid overeating. If symptoms recur, it is recommended to keep a food diary to help identify foods you are allergic to, and consult a doctor if necessary for professional guidance.
