Urticaria usually requires avoidance of spicy and stimulating foods, high-protein foods, seafood, and pickled foods, to prevent any adverse effects on the body. Here are the details:

1. Spicy and Stimulating Foods

Common spicy and stimulating foods include chili peppers, pepper, and onions. These foods are pungent and can irritate the body, potentially worsening the condition and hindering recovery.

2. High-Protein Foods

Foods high in protein, such as beef and lamb, contain relatively high levels of protein and heterologous proteins. Consuming these foods may stimulate the immune response, leading to increased skin itching, rash, and other symptoms.

3. Seafood

Seafood items like crabs, tuna, and shrimp have high levels of heterologous proteins. Eating these foods may irritate the skin and exacerbate allergic reactions.

4. Pickled Foods

Pickled foods such as pickled vegetables and preserved meat contain relatively high levels of nitrite and other allergens. Consuming these foods can easily worsen the condition.

In addition, it is also advisable to avoid mushroom-based foods like shiitake and enoki mushrooms, as they may affect your health. If you experience any discomfort after eating these foods, it is recommended to seek medical attention at a formal hospital to avoid delaying treatment.
