Why do some people have food allergies?

Food allergy is a common disease, which can cause discomfort in the skin, digestive tract and other systems. Because everyone's physical condition is different, everyone has different allergens. Some children are prone to food allergies. Why on earth is this?

Why can food allergy

Everyone's physical condition is different, so any food can cause allergies. Although parents take good care of their baby, there will also be baby food allergy. Why on earth?

1. Intestinal mucosal barrier can protect our intestines, block macromolecular substances from entering the body and reduce our allergy. As the baby's physical development is not mature and the protective function of intestinal mucosal barrier is not fully developed, some substances can still enter the blood through intestinal mucosa, causing allergy.

It can inhibit the absorption of allergens in the gastrointestinal tract and reduce the probability of allergen transport in the human body. However, the immune level of the baby's gastrointestinal tract is low, so the content of immunoglobulin is low, which may enable the transport and absorption of allergic substances and increase the possibility of allergy.

3. There are many beneficial bacteria in the human intestine, which protect our intestinal barrier. Ordinary milk protein formula or antibiotic abuse may damage the beneficial bacteria in the baby's body, which will also make the baby prone to allergies.

What are the symptoms of food allergy

Some wheat products and bean products, such as soybean milk and tofu, are also prone to allergies. Therefore, children under one year old should try to avoid eating soybean milk.

2. Some seafood and shell foods, such as fish, crabs, shrimps, oysters, etc., are easy to cause allergies. Although these foods are rich in protein, they are also easy to cause reactions such as dyspnea, urticaria, anaphylactic shock and so on.

Although milk and eggs are the most common foods and are also known as nutritional saints, they can also cause allergic reactions. Many children under the age of one have allergic reactions to milk, but this situation may change when they grow up.

What about food allergy

If you eat improperly, it is easy to have food allergies, and some allergic reactions will have an impact on our lives. If food allergy occurs, we should take some measures to alleviate it. First of all, we should find the source of allergic reactions. Beef, seafood and other foods common in life are easy to cause allergies. Such foods should be kept away from. In addition to avoiding foods that are easy to cause allergies, we should also eat more nutritious fruits and vegetables to enhance our own resistance and help reduce the occurrence of allergic reactions.

If food allergy occurs, the resistance of the human body will be greatly reduced. At this time, we should stay away from the harmful bacterial environment.

How to prevent food allergy

Although the baby is not fully developed and is prone to allergies, parents can also pay more attention to avoid food allergies in their daily life. So how to prevent food allergy?

1. When breastfeeding, we should try to prolong the time. Breastfeeding should be used when the baby is six months old, which is beneficial to the formation of various antibodies in the baby. During this period, the mother should also pay attention to her body and avoid eating things that are easy to cause food allergy.

2. In the first year of the baby's birth, the diet should focus on some foods that are not easy to cause allergies. Supplementary foods should not be added too early. They can be added week by week, starting with vegetables, fruits, rice and other foods. If there is allergic constitution, the time of adding supplementary food can be postponed.

When adding solid food, pay attention to observe whether there is allergic reaction before adding new food. Do not add a variety of new food at one time, so as not to distinguish allergens. The probability of allergic reactions can be reduced by processing food.
