Eczema is an allergic skin disease. If the patient is not allergic to eggs, he or she can eat eggs; if the patient is allergic to eggs, he or she should not eat eggs. In the clinic, we often tell patients that they must pay attention to their diet and try not to eat fish and shrimp, beef and mutton, mushrooms, bamboo shoots, drinking alcohol and other so-called hair products. Different people may have different hair products, such as people who live by the sea for a long time, mainly seafood, may be tolerant to fish and shrimp, so he is not allergic to seafood, he will not be required to avoid these things; Northwest people are mainly beef and mutton, long-term exposure is also not allergic. So different people will have different dietary requirements for him.
