food allergy refers to the abnormal immune response of the body to the ingredients in food, resulting in physiological dysfunction or tissue damage, which leads to a series of clinical symptoms. Some people think that food allergy is & ldquo; Skin rash, itching to hit the wall & rdquo;, In fact, the manifestations of food allergy vary from person to person. Skin rash is only one of its manifestations. It is often manifested as gastrointestinal discomfort, oral ulcer, asthma and so on. Severe anaphylactic shock may occur. Let’s follow and learn about it!
What foods can cause allergies?
there are many foods that can cause allergy, but for most people, the foods that are easy to be allergic mainly include the following categories:
grains and their products containing gluten, such as wheat, rye, barley, oats, spelt wheat or their hybrid strains;
crustaceans and their products, such as shrimp, lobster, crab, etc;
fish and their products;
eggs and their products;
peanuts and their products;
soybeans and their products;
milk and dairy products, including lactose;
nuts and their kernel products, such as almonds, hazelnuts, walnuts, cashews, pecans, Brazil nuts, etc.
allergies caused by the above foods can account for about 90%. In addition, fruits, such as oranges, kiwifruit, strawberries, bananas, etc; Meat, such as beef, mutton, chicken, pork, etc; Other foods, such as celery, mustard and sesame, may cause allergies.
How does food allergy break?
unfortunately, at present, we have no means to completely cure food allergy. We can only rely on the method of not eating allergic food. Therefore, people with allergic constitution are generally very careful with food. However, it’s better to say that a single food is afraid of some complex compound foods. I don’t know if there will be something in it that can make me win. There’s a kind of & ldquo; The enemy is dark and I am bright & rdquo; It feels like gambling when buying. What should I do?
the best way is & ldquo; Pull the enemy out of the shadow and expose him to the sun & rdquo;, That is, clearly write down what allergens are contained on the food label, so as to know yourself and the enemy and prevent eating allergens.
Allergen labeling is very important
labeling allergen information on food labels is very important to avoid food allergy and protect consumers’ health. At present, many countries require clear labeling of allergens, such as the United States, Japan and so on. However, China’s national food safety standard general principles for the labeling of prepackaged food (gb7718-2011) does not require the labeling of allergen information. Therefore, the labeling of allergens in domestic foods is not standardized at present. Some foods are not labeled at all, and the labeled foods are in different forms. Even if some foods are labeled, they are not easy to find. Therefore, many experts suggest that we should pay attention to this problem and standardize the labeling of allergens.
in addition, China’s export foods are often recalled because they are not labeled with allergens or allergens are unqualified, which has an adverse impact on export enterprises. Therefore, whether from the perspective of protecting consumers’ health or international trade, we should improve food label management and pay attention to allergen information.
Three tips to deal with food allergy
1 and identify
rapid food allergy can occur quickly after eating, and the patient can find it quickly; However, late-onset food allergy often occurs about two hours after eating, which is difficult to contact with eating. This requires the joint efforts of patients and medical staff to ask and recall the medical history in detail. The patient can cooperate with the doctor to record the food diary, which is helpful to find the allergic food. By recalling the medical history and food before the onset, a safer skin prick test and serum allergen IgE examination were carried out for highly suspected allergens to clarify the diagnosis of food allergy.
2 and
mild food allergies can be naturally relieved or improved after giving anti allergic drugs. For patients with severe food allergy, the key to treatment is to quickly alleviate respiratory obstruction and circulatory failure. Intramuscular adrenaline should be preferred. If the attack is far away from the hospital, the high-risk objects who may have anaphylactic shock should be equipped with adrenaline drugs and injection devices to teach patients to save themselves in case of accidents. This has become the main way for most countries to rescue anaphylactic shock at the first time.
3. Prevention
the principle of prevention can be summarized into four words: avoidance, avoidance, substitution and removal. One of the most effective ways is to avoid eating foods known to cause allergies. The reaction of some infants to allergic food will disappear when they grow up, and the phenomenon of allergic food can gradually weaken or disappear after adults avoid eating allergic food for 1 ~ 2 years.
