Postponement of non-staple food cannot avoid allergies.

Before 2008, people naturally thought that the later the allergic food was added, the better. However, after 2008, this concept began to be revised, and it was slowly discovered that such a delay could not avoid allergies. In recent years, research has further reversed this concept and found that the later you add these foods that are considered allergic, the more likely you are to suffer from asthma or allergic rhinitis.

Sleeping Beauty and Spindle VS Non-staple Food and Allergy The king in the story of Sleeping Beauty, in order to get rid of the witch's curse, destroyed spindles all over the country and prevented them from appearing in front of the princess. However, when sleeping beauty grew up, driven by curiosity, she met an old spinning woman and accidentally let the spindle pierce her finger, thus falling into a deep sleep. If the king changed his way and taught the sleeping beauty how not to be stabbed by the spindle at an early age, could he rewrite the whole story?

The same principle can also be applied to the relationship between non-staple food and allergies. Before 2008, people naturally thought that the later the allergic food was added, the better. However, after 2008, this concept began to be revised, and it was slowly discovered that such a delay could not avoid allergies.

In recent years, research has further reversed this concept and found that the later you add these foods that are considered allergic, the more likely you are to suffer from asthma or allergic rhinitis.

Is it easy to be allergic to non-staple food if it is added too late? Before defining the relationship between non-staple food and allergies, we must first clarify the difference between the following two situations. The first situation is that the food the baby has eaten is really allergic; The second situation is the food that others are allergic to. The baby has never eaten or eaten it, but he is not allergic.

In the first case, for this kind of food, as long as it is not serious enough to cause allergic shock, you can pause for a month or two and try again, and you have the opportunity to change from allergic to non-allergic. This kind of food tolerance, after 4 months, the earlier you try it, the greater the chance.

The most famous study is to compare Jewish children living in Britain and Israel. The study found that Jewish children in Britain dared to start feeding them peanuts later, but they were more allergic to peanuts when they grew up than Jewish children in Israel.

The second situation, if you are not allergic after eating it, is what we are most happy to see. A study published on 20 12 pointed out that infants who eat wheat, rye, oats and barley after five and a half months, fish after nine months, and eggs after 1 1 month are more likely to suffer from allergic rhinitis, and the latter two are also more likely to suffer from asthma.

There are more and more studies like this, showing that if a certain food is added after a certain point in time, it will easily lead to heterotopic constitution.

After introducing these two situations, when should these allergic non-staple foods be added? Of course, it is not unlimited to add as soon as possible, at least until the baby is 4 months old, has the basic digestive ability, and the gastrointestinal mucosa has established a preliminary defense.

At this time, we should first consider the form of food, such as rice soup and 10 times porridge, and don't jump to dry rice at once. The second consideration is the nutritional complementarity with breast milk or formula milk. For example, add egg yolk first and then add protein, because there are more ingredients in egg yolk that are not enough for breast milk.

Allergy is the last consideration in the process of adding non-staple food. And maybe in the near future, what we are discussing is how old we should eat shrimp, so that we will not be prone to allergic rhinitis or asthma in the future!

Which foods are allergic? Which foods are more susceptible to tolerance? Taipei Rongzong investigated the main food allergens in Taiwan Province Province as follows: eggs, milk, crustaceans, fish, mollusks (clams, shellfish, midges, squid, octopus) and peanuts.

Secondary food allergens include mango, kiwi fruit, papaya, peach and plum, bamboo shoots, citrus, corn, beans, wheat, almonds, cashews, chestnuts, pine nuts, hazelnuts, pistachios and walnuts.

Among them, children's tolerance to milk and beans is higher than that of peanuts or shrimp. A study published on 20 12 in the United States found that children who are allergic to eggs are the most susceptible to tolerance, and more than half of them are no longer allergic to eggs at the age of 7.

Anaphylactic shock! This is the most serious allergic reaction, which occurs quickly and can be fatal. It can cause laryngeal edema, bronchospasm, hypotension, myocardial ischemia and arrhythmia. Foods that cause this reaction should be avoided for life. In addition to paying attention to the labeling of food content on the package, foods that may be contaminated should be avoided even if they are not labeled.
