What causes egg yolk allergy in children?

We know that many people in our lives are allergic to certain substances, the most common of which is pollen. But the egg yolk can also cause allergies. Some children may be allergic to egg yolks, but many people don’t know what is going on. Therefore, we need to have a detailed understanding of this knowledge. After understanding the knowledge about children's egg yolk allergy, we can better protect their health.

1. The iron stored in the baby's body is gradually consumed 5-6 months after birth, so it is necessary to add iron-containing foods 4 months after birth, and in most cases egg yolks are added. However, adding egg yolk may sometimes cause allergic reactions such as eczema in a small number of infants. However, the reason why adding egg yolk causes allergic reactions is not the egg yolk itself, but because the substances in the egg white that cause allergic reactions enter the egg yolk.

2. You should know that the substance in eggs that is related to allergic reactions is mainly a component called "ovomucin-like protein", which is mainly found in egg white. When the egg is fresh and the yolk membrane is not damaged, the substance cannot enter the yolk. However, when the egg yolk is loose or cooked, the function of the yolk membrane is destroyed, and the "ovomucin-like protein" does not coagulate, so it can quickly diffuse from the egg white to the yolk. If the yolk and egg white are separated immediately after the eggs are cooked, the amount of "ovomucin-like protein" that enters each egg yolk is only 4.8 micrograms. However, if the egg yolk is taken out after being left for 2 hours, the content of this substance in the egg yolk can increase to 78.8 micrograms, which is 16.4 times the former. Excessive "ovomucin" is an important factor in inducing allergic reactions in infants. Therefore, the egg yolks fed to babies must be fresh, and the yolks and egg whites must be separated immediately after being cooked. Do not wait until they are cold before taking them out, and do not soak them in cold water. This should be paid attention to.

3. The most effective way to avoid allergic reactions when feeding egg yolk to babies is to separate the egg yolk from the egg white immediately after the eggs are cooked. If your baby is allergic to egg yolk, it may be related to his allergic constitution and allergy to animal protein, so we can postpone adding it for the time being. Babies with iron deficiency should consume more iron-rich foods, such as animal liver, whole blood, meat, fish, poultry, followed by green vegetables and beans. Black fungus, kelp and sesame paste are rich in iron. Oysters, beef, liver, snails, fish, and lean meat are high in zinc and easily absorbed. There are also pumpkin, eggplant, cabbage, etc.

Through the introduction of the above knowledge, we have learned about egg yolk allergy in children. The editor reminds everyone that you can also take some iron supplements under the doctor's instructions. Because the baby is still young, many foods cannot be added right away. Mothers should pay attention to adding complementary foods properly! You can slowly add egg yolks after the baby is six months old. Pay attention to starting from a small amount to a large amount. If the baby is still allergic, he can't eat it.
