1 to learn about common allergens.

First of all, it is very important to know which foods your baby is allergic to. Milk, eggs, seafood, wheat, soybeans, peanuts and nuts are seven kinds of foods that are easy to cause baby food allergies.

Compared with western countries, although the prevalence of food allergy in Asia is relatively low, the prevalence of food allergy in eggs and milk is comparable to that in westerners. And some researchers have tested the serum samples of 5 190 children aged 3 ~ 12 in China serum bank. The results show that the most important foods for children's allergic reactions mediated by immunoglobulin E(IgE) in China are milk and eggs, followed by beef and nuts [4].

2. The principle of complementarity

Like the basic principle of normal baby complementary food, the principle of complementary food should follow the principle of "from single to diverse, from small to large, from thin to thick, from fine to thick".

After understanding some common allergic foods, for allergic babies, the order of adding complementary foods should start with non-allergic foods, such as rice, millet, fruits and vegetables, meat and so on. , and then try to add meat, eggs, fish and other foods with high allergenicity.

Close observation is needed within 3~5 days after adding complementary food. Once symptoms appear, stop adding complementary food for about 2 weeks to determine whether it is food allergy. However, it is not necessary to stop all complementary foods during this period, and the complementary foods that have been successfully added can continue to be added.

Step 3 avoid allergens

For a baby who has been diagnosed as allergic to a certain food, complementary food can be arranged by avoiding the allergic original. However, avoiding allergens does not mean that the body does not need nutrients in allergens. At this time, you can replace it with other foods containing corresponding nutrients, and pay close attention to your baby's growth and development. Generally, avoid allergens for 3 to 6 months, and then try to add this food.

4, insist on breastfeeding

Breast milk provides the most suitable nutrition for the growth and development of babies. At the same time, immunoglobulins and antibodies in breast milk contribute to the development and maturity of the infant's immune system and to the improvement or desensitization of allergies. The daily diet of lactating mothers should also be diversified, which will also reduce the baby's allergy rate to some extent.
