Patients with herpes zoster need to pay close attention to their diet. Firstly, they should avoid overly greasy and overly spicy foods. Seafood and barbecue should also be avoided as much as possible. Smoking and drinking alcohol are prohibited. Secondly, patients with herpes zoster generally have lower immunity and weaker constitutions. Therefore, it is recommended to eat more soy products, or foods rich in protein, such as fish and lean meat. It is also necessary to consume plenty of fresh vegetables and fruits, and eat foods that are easy to digest. Lastly, patients with herpes zoster should try to eat fewer acidic foods, such as spinach, carbonated drinks, and other beverages that contain additives.
