Tips:
Allergens contained in food may have some cross-cutting. Simply put, people who are allergic to one food are allergic to another food, because these two foods contain the same allergen, which leads to the same food allergy in different foods. For example, people who are allergic to milk may be allergic to goat milk, which is the reason. Foods that can interact include: spices and celery; Peanuts and soybeans; Milk and goat's milk; Milk and meat.
What are the common symptoms of baby food allergy 1, digestive tract symptoms:
Vomiting, refusal to eat, mucus diarrhea, constipation, etc.
2, respiratory symptoms:
Runny nose, sneezing, stuffy nose, cough, etc.
3, skin symptoms:
Urticaria, eczema, dry skin, etc.
note:
In fact, all the symptoms of allergy are not unique to it, such as diarrhea, constipation and vomiting, which can also be caused by other reasons besides allergies. But the baby is allergic to food, which is related to eating. If the baby has allergic symptoms after eating a certain food, the symptoms will be relieved by itself after stopping eating this food. This situation may be caused by food allergies.
Why is the baby allergic to food 1 and the baby's intestinal barrier function is not yet mature?
Under normal circumstances, the intestinal mucosal barrier can effectively block harmful macromolecules from entering the body, but the baby's intestinal mucosal barrier is immature, the arrangement of mucosal barrier cells is not tight, and macromolecules can easily enter the blood directly through the intestinal mucosa, which leads to allergies.
2, the baby's intestinal bacteria has not been fully established:
The intestines of newborn children are sterile, and after birth, intestinal bacteria need to be gradually established. When the intestinal bacteria are not completely established, it is impossible to form a protective film on the intestinal surface, which makes it easy for allergens to drive straight into the blood, so the baby is more prone to allergies.
What should I do if my baby is allergic to food 1? Avoid foods that cause allergies:
For example, babies who are allergic to milk protein should strictly avoid eating milk protein and foods containing milk ingredients.
2. Baby allergic to 0- 1 year-old milk protein:
At present, the accepted recommendation in the medical field is that if breastfeeding is not possible, the formula of completely hydrolyzed milk protein should be selected. The vast majority of babies have symptoms relieved or disappeared within two weeks after receiving the completely hydrolyzed protein formula. If the baby's symptoms are still not relieved after using the completely hydrolyzed protein formula, amino acid formula powder should be used at this time. With the growth of age, the baby's immune system is gradually maturing. After the baby's allergic symptoms completely disappear for 3-6 months, it can gradually transition from amino acid formula to completely hydrolyzed formula, and then from completely hydrolyzed formula to moderately hydrolyzed formula, thus helping the baby to transition to a normal diet.
How to prevent baby's food allergy
1, exclusive breastfeeding should last for 6 months;
The risk of allergic diseases in infants who have been exclusively breastfed for more than 4 months or partially breastfed for more than 6 months is significantly reduced.
2, 6 months began to add complementary food:
Iron-containing rice flour is added first instead of egg yolk. Especially for children with a family history of allergic diseases. Supplementary food must be added one by one, and each supplementary food should be observed for 3-4 days, and new food should be added without adverse reactions.
3, food substitution method:
Parents should not blindly taboo some foods for their children, but can use other foods with the same nutritional value instead of sensitized foods.
4. Mothers with a family history of allergies should avoid allergic foods:
It is suggested to postpone the time of breast-feeding and the time of adding dairy products, eggs, fish, nuts and beans to the baby. For newborns or infants with family history of allergies who are fed by mixed feeding or artificial feeding, it is suggested that when adding formula milk, partial or complete hydrolysis of formula milk powder is the first choice, which can effectively reduce the incidence of food allergies or alleviate symptoms. With the growth of the baby's age, moderate hydrolysis can be converted into ordinary formula milk powder when the doctor's allergy test passes.
