It is usually not recommended to take mangoes after drinking beer. If there is no previous allergy to beer or alcohol overdose or alcohol poisoning, and there is no history of mango allergy, a small amount of mangoes can be taken after drinking beer, and the patient’s condition and reaction must be strictly and closely observed. However, if a beer allergy has existed in the past, or if a patient with severe alcohol poisoning has occurred, and if there is a previous history of mango allergy, it is not acceptable to eat mangoes immediately after drinking beer. If you eat mangoes, it can lead to serious alcoholism, alcohol allergy, or serious allergic reactions to mangoes, because mangoes are rich in an inflammatory mediator called histamine, which is particularly likely to lead to increased vascular permeability and aggravation of allergic reactions, which can easily mediate allergic reactions after drinking beer, so it is not recommended to eat mangoes after drinking beer.
