Allergies to substances can be seen everywhere in daily life, and many people have experienced this pain. The World Health Organization (WHO) points out that 22% -25% of people worldwide suffer from allergic diseases, and the number is increasing year by year, with food allergies accounting for the vast majority. Professor Ma Guansheng from the School of Public Health at Peking University reminds netizens that we do not have a complete cure for food allergies, and can only prevent allergies by avoiding foods that cause allergies. Food allergy refers to the abnormal immune response of the body to the components in food, leading to physiological dysfunction or tissue damage, and subsequently causing a series of clinical symptoms. Some people believe that food allergy is like "a rash on the skin that itches like hitting a wall". In fact, the symptoms of food allergy vary from person to person, and skin rash is just one of its manifestations. It is also often manifested as gastrointestinal discomfort, oral ulcers, asthma, etc. In severe cases, allergic shock may occur. What foods can cause allergies? There are many foods that can cause allergies, but for most people, the main categories of foods that are prone to allergies include 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 nut products, such as almonds, hazelnuts, walnuts, cashews, American walnuts, Brazilian nuts, etc. Allergies caused by the above-mentioned foods can account for about 90%, in addition to fruits such as citrus, kiwi, strawberry, banana, etc; Meat, such as beef, lamb, chicken, pork, etc; Other foods such as celery, mustard, sesame, etc. may cause allergies. How to solve food allergies? Unfortunately, we currently do not have a complete cure for food allergies, and can only rely on avoiding foods that cause allergies. Therefore, people with allergies are generally very careful when dealing with food. However, it's okay to be afraid of a single food, but I'm afraid of complex compound foods. I don't even know if there might be something hidden inside that could make me vulnerable. It feels like I'm gambling when buying. The best way is to 'pull the enemy out of the shadows and expose them to the sun', which means clearly stating on the food label what allergens are contained, so as to know oneself and one's enemy, and prevent eating allergens. It is important to pay attention to allergen labeling. Labeling allergen information on food labels is crucial for avoiding food allergies and protecting consumer health. Currently, many countries require clear labeling of allergens, such as the United States and Japan. However, China's national food safety standard "General Rules for Pre packaged Food Labeling" (GB7718-2011) does not require mandatory labeling of allergen information. Therefore, the labeling of allergens in domestic food is currently not standardized, and some foods simply do not label them. The forms of labeling vary, and even if they are labeled, it is not easy to find them. Therefore, many experts suggest that this issue should be taken seriously and allergen labeling should be standardized. In addition, China's exported food is often recalled due to not labeling allergens or labeling allergens improperly, which has a negative impact on export enterprises. Therefore, whether from the perspective of protecting consumer health or international trade, it is necessary to improve food labeling management and attach importance to allergen information.
