If allergy sufferers want to eat duck eggs, they first need to clarify whether they will be allergic to duck eggs, and if they are not, they can eat them. Duck eggs have a certain effect of nourishing Yin and clearing the lungs, and their protein content is comparable to that of eggs, while the total amount of minerals is higher than that of eggs, especially rich in iron and calcium, which can prevent anemia and promote bone development to a certain extent. Duck egg is not a common allergen, but it is a high-protein food that can act as a semi-antigen to stimulate the body to produce antibodies, leading to the occurrence of allergies. Allergies are mainly allergic lesions mediated by IgE. Anyone who is genetically, or physically, susceptible to a specific antigen may have a rapid-onset, or delayed-onset, allergic reaction after exposure to the antigen in question. If the patient is allergic to duck eggs, consumption will cause more severe allergic reactions, with severe respiratory distress, throat edema, or even anaphylaxis. If an allergic reaction occurs it must be treated promptly and during the treatment period attention must be paid to the diet and away from foods that can aggravate the allergy. Therefore, people who are clearly allergic or hypersensitive to duck eggs need to clarify whether they can eat duck eggs and take precautions against allergic reactions to avoid anaphylaxis.
