Allergic symptoms in infants are increasing year by year, and eczema is one of the manifestations of allergic symptoms. First, eczema has a great relationship with genetics, if the baby’s parents have a history of eczema, or allergic to certain foods and environmental factors, you should try to avoid exposing your baby to substances that may cause allergies; second, wool, artificial fibers, pollen, sweat, urine, dry air can trigger eczema, babies with eczema should stay away from these environments. Third, food is also an important cause of eczema in babies. Milk and formula contain a lot of foreign proteins, which can cause allergies in some babies, and some babies are allergic to eggs, fish, shrimp, crab, chocolate and other foods. Infant milk allergy is actually an allergy to the proteins in milk, which means that it is caused by the baby’s body’s immune system overreacting to milk proteins. Deeply hydrolyzed proteins are processed through a protease hydrolysis process, which greatly reduces the allergic components of milk proteins, making the modified milk proteins less allergenic, i.e. hydrolyzed proteins. Allergic eczema should be treated with the right milk. The first step in treating infants with allergic eczema is to identify the allergen. Only after the allergen is identified can the milk be “allopathic”, even if it is a milk protein allergy. If the symptoms are mild, there is no need to use deeply hydrolyzed milk powder, as the child grows older and the body matures, most allergy symptoms will heal naturally. General hospital blood tests can find out if your baby has a protein allergy. Almost every brand of milk powder on the market has hydrolyzed protein milk powder, but drinking deeply hydrolyzed milk powder can only prevent milk protein allergy and has no effect on other allergens. Therefore, deeply hydrolyzed milk powder is not actually a medicinal milk powder, let alone a “cure-all” for infant allergies. In addition, the nutrition of hydrolyzed protein milk powder is similar to normal milk powder, so mothers do not have to worry about the nutrition of their allergic babies.
