What causes a three-year-old to be allergic to milk?

Many people are naturally sensitive to some things, such as seafood allergies, flower allergies, or allergies to certain foods, etc. These are all normal phenomena. As long as the patients avoid contact with allergens in daily life, they will be fine. However, some three-year-old children are allergic to milk. Although this is a healthy disease, it will still have some effects on the children and make them feel uncomfortable.

1. Milk allergy is a health condition but is often mistaken for lactose intolerance. Although both are related to milk, they are different.

2. Milk allergy symptoms occur when the human immune system produces antibodies to the proteins in milk.

3. The milk we consume is composed of carbohydrates, water, minerals, fat, protein and some other substances.

4. 30 different proteins can be found in milk, divided into two groups: casein or whey protein. Proteins belonging to the casein group are heat stable and cannot be utilized by thermal decomposition. Proteins belonging to the whey protein group can be thermally decomposed. Symptoms of a milk allergy vary from person to person; some people will have an immediate reaction, while others may develop symptoms hours or days later. There are three types of milk allergies: An adverse reaction occurs immediately after consuming even a small amount of milk.

In the above article, we mainly introduced the reasons why three-year-old children are allergic to milk.
