In order to avoid allergies, it is best not to add egg yolks to supplement foods. Babys may have allergies when eating egg yolks.

The prevalence of food allergies is less than 1 year old, especially 4-6 months after the beginning of supplementary food. In order to avoid or minimize the occurrence of food allergies in infants, the following issues should be paid attention to in the process of adding complementary foods:

Insist on breastfeeding and avoid adding premature supplements

At present, domestic and foreign experts agree that exclusive breastfeeding is one of the most effective ways to prevent food allergies in infants. This is because:

In the immature stage of the baby's intestine, breastfeeding can reduce the chance of exposure to foreign proteins;

Breastfeeding can play an anti-infective and anti-allergic role by promoting the growth of probiotics such as Bifidobacterium and Lactobacillus;

Specific antibodies in breast milk can induce intestinal mucosal tolerance, thereby reducing the occurrence of allergic reactions. Therefore, in the first 4 months of the baby, try to use exclusively breastfeeding; after 4 to 6 months, add supplementary food. Babies with a family history of allergies should especially emphasize exclusive breastfeeding for the first 4 to 6 months, and should continue to breastfeed for 10 to 12 months.

Because food allergies are also related to genetic factors, couples with a history of food allergies should beware of foods that have caused their allergies in late pregnancy to avoid indirect allergies through breast milk. During breastfeeding, mothers should avoid eating foods that can cause allergies.

Pay attention to the order of selection and addition of complementary foods

Studies have found that common allergenic foods for babies are milk, eggs, peanuts, soybeans, fish and shrimps, shellfish, citrus fruits, wheat, etc. Most food allergens are glycoproteins. About 40 different proteins in milk may have sensitizing effects. Egg proteins, egg mucins, and egg transferrins in eggs can also cause allergies. Cod, soy, and peanut also have a variety of antigens that can induce allergies. In addition, some food additives such as artificial colors, preservatives, antioxidants, flavors, etc. can also cause allergic reactions. Therefore, such foods should not be introduced prematurely during the supplementation process.

The first type of complementary food introduced to infants should be food that is easy to digest but not easy to cause allergies. Rice noodles can be used as the first choice of food, followed by vegetables and fruits, and then meat, fish, and eggs. In short, the order of supplementary foods is cereals vegetables fruits meat, fish, and eggs. Foods that are more likely to cause allergic reactions, such as egg whites, peanuts, and seafood, should be provided after 1 year of age.

Master the principle of progressive food supplementation

Adding complementary foods to infants should master the principle of gradual progress from one to many, from small to many, from fine to coarse, and from thin to thick.

Each new food introduced should be a single food, starting with a small amount, in order to observe the infant's gastrointestinal tolerability and acceptability, and timely detect the symptoms related to the newly introduced food, so that you can detect whether the baby has food allergies and reduce Consequences of eating multiple foods.

When trying to give a baby a new food, the baby often shows signs of refusal and uncooperation. Usually, this is the infant's defensive instinct, which can be stopped after 2 to 3 days before trying again. But sometimes infants respond to food allergies only as a protective antifeedant behavior. If the baby continues to reject a certain food, the possibility of food allergy should also be considered, and the introduction should be cautious.

Infancy is a high incidence of food allergies. When adding complementary foods to babies, especially when introducing new foods, food allergic reactions may occur, which not only affects the baby's health and growth and development, but also seriously threatens life. Therefore, parents should learn a little bit about adding supplementary food to avoid or reduce the occurrence of food allergies.
