Original title: Why people with food allergies are becoming more
In recent decades, there has been a marked increase in the number of cases of food allergies worldwide, with 7 per cent of children in the UK having food allergies and 9 per cent in Australia. Why is there a food allergy? Why are more and more people with food allergies? Dr. Sun Jin brigade, director of the Perverted Response Department of Beijing Concord Hospital and chairman of the Special Committee of Allergy Medicine of the China Research Hospital Association, recently answered questions for consumers.become a global public health problem
Food allergies are an abnormal immune response produced by the body's immune system to a particular food, and allergens mistake normal, harmless substances for harmful, resulting in antibodies. A substance that causes allergies in food, called a food allergen, can also be called an antigen.
food allergy has gradually become one of the outstanding problems of food safety and public health emergency. Currently, the prevalence of food allergies among adults in Western countries is close to 5% and among children is close to 8%. In the United States, for example, one in 13 children is allergic to food, and every three minutes there is an emergency case of a food allergy reaction. Although there are no authoritative statistics on adult allergies in China, research has shown that the prevalence of food allergies among children in China is 6.2%, which is much higher than the prevalence of general diseases.
the World Health Organization, 22 to 25 percent of the world's population suffers from allergic diseases, and the number is increasing year by year, with food allergies accounting for a large proportion. According to the World Perverted Reactions Organization, 30 to 40 percent of the world's people are plagued by allergies, which have become the world's sixth-largest disease. In 2016, Yu Jia, director of the Perverted Reactions Section of Beijing Concord Hospital and former chairman of the Perverted Reactions Branch of the Chinese Medical Association, conducted a study of severe allergic reactions and found that food triggers accounted for 77% of patients with allergic shock, drugs for 7%, insects for 0.6%, and the remaining 15% for unknown reasons.
Sun Jin Brigade introduced, China's overall prevalence of food allergies is on the rise, for several reasons: some people died suddenly before, at that time did not know the cause, now the study found that food allergy rescue is not timely, often lead to death. Statistics found that allergy-related deaths tend to increase, more and more ingredients in food (such as peanuts, milk, etc.), leading to food allergy people are easily exposed to allergens, often use hand lotion and other chemicals, weakening the protective function of the skin mucosa, people will become more and more allergic; plasticizer use, haze and car exhaust and other environmental problems may cause allergic diseases, but also lead to more and more allergic reactions, including food allergies;
Food allergy light may cause redness, swelling, itching around the lips, tongue swelling, itching, nausea, vomiting, abdominal pain, diarrhea, blurred vision and other symptoms, serious may cause throat hair tightness, breathing difficulties, blood pressure drop sharply, loss of consciousness and other allergic shock symptoms, rescue often lead to death. In addition, food allergies can affect children's growth and development and quality of life. Children with food allergies are prone to asthma, increasing the risk of respiratory allergies later in life. In general, although food allergies are related to the intake of allergen doses, the threshold for food allergies is very small, and even if you eat only a little allergic food, it is well above the threshold. Moreover, food allergic reactions take a short time, some for a few minutes, some for dozens of minutes, and may even lead to allergic shock death by eating just one bite.8 food products cause 90 per cent food allergies
according to the World Food Organization, more than 90 per cent of food allergies are caused by eight categories of food, including milk, eggs, fish, shellfish seafood, peanuts, soybeans, nuclear fruits and wheat. "People with food allergies must pay great attention to their diet. At present, there is no effective cure for food allergies, patients can only identify as far as possible which food can not touch themselves, and actively avoid eating. Sun jin brigade said.
food allergy in Western countries is the most important peanut allergy, our country is milk, egg allergy more people.
the first food allergy prevalence in China is egg allergy, eggs are also the first allergen that causes allergies in children. According to the survey, the prevalence of egg allergy in China is 3%-4%, far higher than the 1%-1.6% prevalence rate in Western countries. Milk ranks second. Infants and young children are most prone to allergic reactions, in general, the prevalence of milk allergies is 0-3 years old, 4-17 years old adults. Some studies have shown that the prevalence rate of infants under 1 year of age in the Mainland of China is 1.3%, while others have shown that the prevalence rate of children under 2 years of age is 0.83% to 3.5%, higher than in Hong Kong and Taiwan. Peanut allergy ranked third. However, the prevalence of peanut allergy in China is much lower than in Western countries, firstChinese contact with peanuts is relatively lateChinese, children under 1 year of age basically do not eat peanuts;
recent years, it has been found that red meat can also cause severe allergic reactions and even shock deaths. Red meat allergy and tick bites related to the global tick bite caused by red meat allergy cases reported, clinical manifestations are eating red meat 3-6 hours later, the emergence of systemic urticaria, throat edema, respiratory distress and other symptoms.
food allergies caused by buckwheat, peppers, insects, etc. are unique types in China. Sun Jin brigade introduced, buckwheat products in China is increasingly regarded as health food, and buckwheat flour is gluten-free, usually as a supplement for patients with celiac disease, there are many people with wheat allergies to buckwheat as an alternative food, so buckwheat food is more popular. Locusts, cocoons, dragonflies and scorpions are the specialties of many parts of our country, and the intake of these exotic proteins can also cause severe allergic reactions and even death. Pepper is a common dish ingredient in our country, which is rarely used abroad. In addition, china's mango, peach, dragon's eye, kiwi, lychee and other allergies are also many people.to prevent first aid
"It is essential to identify and diagnose food allergic reactions, especially severe allergic reactions, in a timely manner and to take the right rescue measures as early as possible." Sun Jin brigade introduced, food allergy is the first characteristics of the heart, feet itchy, or scalp itchy, numb;
these symptoms, it is clear that food allergies, to be rescued in a timely manner. When the patient's symptoms are mild, 20 drops can be taken under the tongue of the sitilitin drip, and if it is not effective, it is necessary to inject epinephrine immediately or intramuscularly, without epinephrine, and can also be replaced with a methamphetrome injection or a hydrocarbonized pine intravenous infusion.
addition, people with food allergy shock also have a very important feature, some patients 6-8 hours after the phenomenon of re-shock, so be sure to pay attention to prepare the corresponding rescue measures.
food allergies are basically preventable. Prevention should do the following: avoid allergic food, find that a food may cause their own allergic reactions, to avoid eating again. Step-by-step principle. When allergens are not clear, you can first test for allergies to foods you have not tried. Take milk as an example, first put a little milk on the skin or lips, to see if it will cause skin erythema, wind cymbals, mouth redness and other allergic reaction characteristics; There is no allergic reaction and you can eat in small amounts. Wait a while to be completely sure, and then eat with peace of mind. People with allergies should have first aid medicine in place.
of food allergies is increasing year by year worldwide. Sun called on the relevant departments to strengthen health education to raise public awareness of food allergies, and the public to learn to recognize common allergens and eat special foods such as crickets, locusts and silkworms with caution. Relevant departments should also further improve food labelling. Labeling is the only way for consumers to understand the ingredients of prepackaged foods, with one in three people experiencing food allergies attributing allergies to labels. At present, China's relevant standards have added the label of food may contain certain allergens, but the lack of the label does not contain any common allergens. In addition, China's clinical should establish the scientific system of desensitization treatment as soon as possible. (Zhang Jian)
