These delicious for some into a potentially lethal threat. Now more and more fantastic food .allergy have appeared: mango Kiwi allergies, allergies, or even Apple seems to be what are allergies as the source of the allergy. <p> <wbr> </ p> <p> This disturbing topic in late 2007 and early 2008 once again .attracted the attention of the medical profession immunity. </ p> An experiment showed that "the bad" in the course of treatment would probably make some people out of dangerous food allergy. But researchers are still unable to find the causes of allergies, it .can only be attributed to this hypothesis: perhaps because our life too health, too clean. <p> <wbr> </ p> <p> Does anaphylaxis?

You may also be used .for fruit sent this time, but this choice on Xiao Li, but some problems. Not long after, her mouth near to grow small rash, and begin to itch. She wanted to Flex, but also forborne. Because she knows that they have a .food allergy. <p> <wbr> </ p> <p> And the usual common food easily cause allergy, allergy to Xiao Li is not a peanut, milk or fish, but of the fruit. </ p> Not all fruits .are let Stacey. She is just on Rosaceae fruit such as apples, pears, Hawthorn, papaya ... Sensitive, especially members of the Board a branch: peaches, apricots, plums and cherries, and these things to her body have serious allergic reactions .. <p> <wbr> </ p> <p> Today, food allergy has become the most headache health issues. </ p> In the United States, the problem is particularly serious. According to the scientists of the latest statistics, .now has more than 11 million in the United States people are affected by food allergy. Almost all researchers in referring to this number is often also combined with the sentence: this number is still growing. They found that 5 of the United States under the age .of children, the person with peanut allergies, from 1997 to 2002 has doubled. "Obviously, peanut allergy in the adolescent population growth very fast." New York's Mount Sinai School of medicine, food allergy experts Hugh · Sampson (Dr.Hugh Sampson) ., "we expect in the future, this number will increase." <p> <wbr> </ p> <p> The expansion of food allergy problems, not only reflected in the growing number of allergies, also reflected in the increase in .food and aeroallergens. </ p> Allergy experts say that, after the study, they found that the risk of comprehensive allergy symptoms, the number of children is increasing, and cause allergic food pedigree of children increasingly broad. <p> <wbr> .</ p> <p> In the 1950s, had only two main food is found to be likely to cause allergic symptoms of mankind: milk and wheat. </ p> Today, this list is getting longer and longer. Now recognized easily trigger .allergy symptoms of food extended to 8: peanuts, nuts, fish, shellfish, eggs, milk, soybeans and wheat. According to statistics, at least 90 percent of food allergies and the 8 kinds of food. Of these, peanuts are one of the .most important aeroallergens. The problem is that in addition to these eight categories of food, now researchers have found that at least 170 kinds of foods can cause allergic reactions, almost all of the newly introduced food might let some children appear allergy symptoms, and the .components of complex food additives even more of a hypersensitivity to guard against. <p> <wbr> </ p> <p> Thus, parents on every new food have misgivings, they don't even worry about the child from the classmate or .friend to a new allergy symptoms. </ p> At the same time, in many countries, "monitoring" children eat new symptoms caused by food, also became a compulsory course for parents: If your child is eating some new food after eruption, .symptoms such as diarrhea, vomiting, note that this may mean that he is allergic to this kind of food. Children's Hospital of land and LUN by allergy experts Dr. pointed out that, in general the Los, allergy is eating into the food after several .minutes, usually reflected in the body or rashes near the mouth. Baby's digestive system disorders can occur, such as nausea, vomiting, or stomach pain, rare allergic reactions occur in laryngitis, asthma, and is called "allergic shock" systemic reactions. < .p> <wbr> </ p> <p> Based on these issues, in the United States, many schools established a "restricted area" peanut. </ p> A number of cantons have also developed a guidance manual for the prevention of .allergies. Many airlines will no longer supply the peanuts and crackers instead. In August 2004, the adoption of the United States also allergy to food source identification and consumer protection statute, the ActRegulatory requirements for food producers in the simplest language marking food composition. This .is the United States for the first time in history in the form of legislation expressly requires the identification of food allergy. For example, if the food contains the above 8 cause allergic reactions of the main food component, it must be clearly identified on food labels .. If you are involved in fish, shellfish or tree nuts in the three groups of producers of food allergy sources, you must mark the specific food name. At the same time, if the seasonings, spices and pigment containing any kind of aeroallergens, must .also be indicated. <p> <wbr> </ p> <p> <wbr> </ p> <p> [Response] there is also a defense mechanism of the human body </ p> <p> <wbr> .</ p> <p> Unprepared allergy, parents time somewhat by surprise. </ p> Fortunately, not everyone will experience symptoms of food allergy. <p> <wbr> </ p> <p> The PLA General Hospital nutrition practitioners .Liu Ying-hua, food allergy refers to certain substances in food (usually a protein) into the body, body content of the immune system as invading pathogen, the occurred immune reaction, an adverse effect on the human body. </ p> Under .normal circumstances, your body will produce antibodies used to protect the body from disease, this is the so-called immune system. The problem is that some allergy 'body will normally harmless substance mistaken for harmful things, produce antibodies, it becomes a kind of ."aeroallergens." This kind of allergic reaction can cause some physical issues. Food in 90% of the allergen is a protein, but not all proteins will cause allergies, such as milk protein containing more than 20, of which 5 can cause allergic reactions .. <p> <wbr> </ p> <p> It is worth noting that the food allergy and food intolerance is different. </ p> Food intolerance does not involve the immune system, usually consisting of digestive enzyme deficiency. For example ., some people feel after drinking milk or abdominal distension, abdominal pain or diarrhea, "this is due to its lack of lactase in the body, so that the lactose in milk cannot be broken down, the most common is lactose intolerance." <p .> <wbr> </ p> <p> Medicine, allergy (allergic) is divided into four different categories, with Roman numeral I to IV. </ p> China Agricultural University, Associate Professor of food and nutrition Jack red pointed out that .in the hospital, usually food allergy is also known as "type I allergic response". <p> <wbr> </ p> <p> With food allergy opposed section referred to as "the crowd tolerance" that is, no response to .the food allergy. </ p> Most people on allergenic substances is not responding, even on a class of substances, the allergic reaction may only be temporary, sometimes allergy, allergy, sometimes because the body will produce the appropriate defense mechanisms. <p .> <wbr> </ p> <p> The esophageal mucosa and gastrointestinal effects generated by the barrier, is we have the first secret weapon. </ p> The weapons of magic, is available through non-immune or immune mechanism to prevent .the entry of homologous Antigen. Once this door is compromise, the body also took out a door with door, that is the body of inside the body of food antigens for centralized approaches fate, including the Antigen vesting to peptic substances, by inducing immune responses .out of Antigen, produced for food intolerance and allergy. <p> <wbr> </ p> <p> Of course, in their own food aeroallergens defense mechanism is not mature or is defective, if exposure to pulsed sources of food, it .is easy to produce allergic reactions, often induce allergic reactions: gastrointestinal, food allergy to the most common way is the organ most prevalent; respiratory reactions, highly sensitive children in boiling milk, fried egg, process food smells can also be induced disease; skin ., highly sensitive people in contact with skin allergies to food or skin test can also be induced symptoms; placenta, mother's serum antibody may accidentally through the placenta to the fetus by passive anaphylaxis. </ p> <p> <wbr> </ p .> <p> "Food allergy can occur at any age and gender, but good in infants and young children and women. </ p> As a result of food allergy in infants are most likely to occur, often causing parents to feed, being .afraid kids eat after allergy, fearing that the children do not eat after causing malnutrition, food allergy is secondary malnutrition in children. "Liu Ying-hua. Due to allergies and other immune system disorders there are incidental. Therefore, in people with lupus, .arthritis, and other immune system disorder in patients with eating fish, eggs, special attention must be given to prevent allergy symptoms. <p> <wbr> </ p> <p> <wbr> </ p> <p> [Genesis .] hygiene also excessive? </ p> <p> <wbr> </ p> <p> However people confusing is that why is now the children suffer from food allergies a sharp increase in the number of? why peanut butter sandwiches, chocolate .cake, and even a glass of ice milk, it will allow thin body is allergic. </ p> <p> <wbr> </ p> <p> Scientists gives an interesting explanation: all this change because "we become too clean .. "</ p> This is the so-called" hygiene hypothesis ". Jack red pointed out that, since the human immune system's main feature is the resistance such as parasites, viruses, and infection, alien invaders, but more clean water, .antibiotics and vaccines weakening its resistance, it is difficult to distinguish what is enemy, friend, and ultimately can only throw resistance a gas. Research shows that those longer than rural children although often and soil, animal contact in this kind of "dirty environments" ., these children rarely appears allergic symptoms. <p> <wbr> </ p> <p> Canada a team of scientists recently published a study reported that at least those longer than rural children suffering from asthma likely smaller - as we all know, .asthma is the most common allergy symptoms. </ p> Scientists at the molecular level compared to the wild environment of rodents and in the lab environment in a similar distinction. In order to compare different immune system, researchers will animals out of immune cells, .and then separately with plant protein, want to see these cellsReaction. <p> <wbr> </ p> <p> The results of the study found that wild rodents of the immune system and not be bothered to prove that they have been experiencing .a lot of similar interference. </ p> "These wild rodents do not appear in the allergy symptoms." The study of William · Parker (WilliamParker) said. <p> <wbr> </ p> <p> To this end ., Toulon's Hospital Children's allergy experts Dr. also pointed out that the Los children allergies increase for several reasons. </ p> Which genetic is a reason. But a close look, we will find our baby was "excessive protection": the regular use .of antibiotics, environment too clean, so that the cells do not have to struggle with the infection, and so on, these are more likely to trigger allergies. In addition, the baby's digestive system is not yet mature prematurely added complementary foods is also a .reason. <p> <wbr> </ p> <p> This issue looks seems to be: the more you focus on it, it will stick to you. </ p> Parents are more careful to protect your baby against foreign invaders .harm children; children are more susceptible to allergies. In fact, some researchers investigate certain evidence of this idea. United Kingdom London Royal College GE den · Lake (GideonLack) through the world of allergic phenomena of tracking, found a very interesting phenomenon: in .the United States, although it has been very Peanut Allergy in infants, stop at food contains Peanut Allergy, however, the proportion of still increasing; in some countries in Asia and Africa, despite the baby's recipe without stress, peanuts and contains peanuts food is .the proportion of patients with frequent visitor, baby or not. <p> <wbr> </ p> <p> However, just because it was so clean and sanitary, food allergy caused by increased, in some scientists also is not a problem .of all. </ p> New approach to health development research center director Wang Ke Ann says that food allergy in industrialized countries are becoming more and more serious, and now also the food processing technology. Due to the complexity of food processing technology, what .process ultimately caused allergy symptoms, scientific researchers in the study. <p> <wbr> </ p> <p> In addition, Los also noted that the discussion of why children are predisposed to allergies, but also genetic factors. </ p .> Most of the infant atopy is affected by genetic family. Baby get the chance for allergic Constitution and one parent or both have the chance for allergic Constitution, 30 per cent, respectively, and 80 per cent. <p> <wbr> </ .p> <p> <wbr> </ p> <p> [Study] need to know a lot of problems still </ p> <p> <wbr> </ p> <p> Food allergy, for many people living .with serious interference. </ p> Some people have been closely monitoring his own food into the mouth, but with any special "prohibited constituents". The famous series "CSI: Las Vegas, has a set description perpetrator use victim characteristics of shrimp allergy ., murder. <p> <wbr> </ p> <p> In this way, a big problem before the scientists: food allergy will become an insurmountable problem? </ p> <p> <wbr> </ p> < .p> This is one of the key is sensitized is a source of easy-to-understand questions. </ p> "In the modern food processing industry, food additives cause allergic reactions are common." Liu Ying-hua. These chemicals are .widely used in various types of food, but because of the food label callout is ambiguous or not tagging, if you do not pay special attention to the often difficult to observe. <p> <wbr> </ p> <p> In recent .years, with the rapid development of biotechnology and genetically modified food constantly enter circulation. </ p> The researchers, some containing genetically modified organisms from allergenic food species and humans have been living species of genes, genetic recombination enables host plants to produce new proteins ., these new protein may have on the human body including allergenicity, toxicity effects. "Now, check food allergenicity is genetically modified food safety inspection of one of the main content, any new commercialization of genetically modified food, all you need to include the allergenicity ., security assessment. "Yinghua stressed. <p> <wbr> </ p> <p> At the same time, many proteins common antigenic determinant, makes sensitive sources have cross reactivity, such as cross reaction can be present in the milk and .goat's milk, eggs and other bird eggs, but not present in the milk and beef, eggs and meat. </ p> Plants of cross reactive than animals, such as allergy to soy may other legume or allergies. <p> <wbr> .</ p> <p> And complex, some are allergenic food and digestive juice of reaction after the allergenic activity, which requires the detection evaluation and processing of the issues into consideration. </ p> <p> <wbr> </ p .> <p> Generally sensitized materials in food is also one of the few, if only in milk casein, letters a milky protein, bovine immunoglobulin and bovine serum albumin and so few protein components have sensitized source characteristics, and after several also has thermal stability ., thus taking measures to prevent sensitization reaction, be sure to clearly cause allergic sensitization source what kind of ingredients. </ p> <p> <wbr> </ p> <p> In fact, there are many more allergic phenomena also plaguing .scientific researchers. </ p> Jack red noted that child, eggs and milk is easier for the two types of food allergies. In contrast, adult allergy to shrimp and crab. Why kids on eggs and milk allergy prone to allergies, later what consequences .will, on this research, the scientific community has begun. <p> <wbr> </ p> <p> Including the Mount Sinai School of medicine, 4 research institutions collected 400 babies in a test. </ p> These babies are .allergic to eggs or milk. In the next five years, the researchers will always "oversight" of the child in order to observe whether they will suffer from Peanut Allergy, which the baby's milk or egg allergy symptoms aggravate. Researchers hope to be at the .molecular levelTo better understand what is causing these infant suffering from allergies. <p> <wbr> </ p> <p> <wbr> </ p> <p> [Resolved] healing Elixir has not been found </ p> < .p> <wbr> </ p> <p> Allergy phenomenon in modern society, more and more complex. </ p> For what is panacea for food allergy? <p> <wbr> </ p> <p> Los pointed .out that, for those who due to genetic and other possible allergic Constitution of baby steps you can take is that exclusive breastfeeding for six months - - whether you have a family history of allergy to add supplementary food in 6 months after birth. </ p .> <p> <wbr> </ p> <p> In fact, allergic for resistance before, the most reliable method is excluded may cause the child to the food allergy. </ p> However, due to the development of the modern .food industry, there is a lack of food, all the ingredients in the formula of accurate information, this method also become unpredictable. <p> <wbr> </ p> <p> To this end, the scientific research personnel also tried to .poison. </ p> In 2005, a food allergy research organization-sponsored research project started. This experiment was a gradual process. Initially, scientists for Peanut Allergy in children to a small quantity of peanut protein in order to test whether they can tolerate .aeroallergens intake. In turn, give them a small dose of peanut taking the amount of the subsequently take a little bit to increase. Scientific researchers hope to achieve with the bad effects. <p> <wbr> </ p> <p> In .fact, this method is used by many scientists. </ p> Although the contents of the respective expand some of the differences, but the general idea is the same. That is to appear in the allergy symptoms in patients with early exposure to micro allergy .food to see if you can prevent deterioration, and ultimately the development of a vaccine to prevent allergies. In their view, this approach inevitably some radical, but is a good attempt. <p> In January of this year's Allergy and Clinical Immunology "magazine .reported United States Arkansas Children's Hospital of Booker (Burks) and steins · Dr. Joan for eggs in medical law. </ p> In nearly two years of clinical trials, they let the patient gradually eat eggs, eventually most of these eggs children can .safely eat two eggs. A 7-year-old on peanut allergy in children, in the attempted NoahSchaffer such therapy, allergy symptoms almost disappear. <p> <wbr> </ p> <p> Booker wanted to stick to that idea, .developed anaphylaxis vaccine. </ p> At present, the Booker in a flower named "peanut" vaccines. Booker stated that through the mouse's experiments have shown, this vaccine can effectively solve the problem of peanut allergy. "We are hoping to get treatment .in humans. "<p> <wbr> </ p> <p> At the same time, the most recent scientific research has confirmed a for resistance to food allergy very important molecules, researchers believe that perhaps will bring a new treatment. < ./ p> <p> <wbr> </ p> <p> In the United Kingdom Institute for Eastern England University food, a by Nick ceretti (ClaudioNicoletti) led the research team found that allergic reactions occur, called Interleukin-12 (IL .-12) molecules disappear. </ p> <p> <wbr> </ p> <p> Prior to this, Nick lazzaretti et al. found called dendritic cells of special white for helping the immune system to determine how to react to .foreign molecule is critical. </ p> In the latest experiment, Nick ceretti compared the allergies of the mouse and the normal mouse intestinal and spleen between dentritic cells of activity. Results found that allergic rat intestinal, dentritic cells stop producing secreti IL-12 .. Nick pointed out that, if present, then inject antigens IL-12 after allergic reactions can be suppressed. "Food for some completely harmless protein may have on others is fatal. And we found that the immune system reaction under control of key elements. ."<p> <wbr> </ p> <p> It seems that everything is in to the good direction. </ p> However, another group of researchers of the laboratory has brought the opposite conclusions. Lake felt these despicable act now .to make a final conclusion is a little premature. At present, the Lake has raised 200 suffer from eczema or egg allergy in infants, carry out an experiment. Of course these babies on Peanut Allergy is not. Baby Lake is divided into two groups, .one group to their feed contains peanuts in food, the other half did not. <p> <wbr> </ p> <p> Lake indicated that he would monitor the situation of peanut allergy in infants: "I don't want everyone .to feel that taking the peanuts can prevent Peanut Allergy, in fact for this result, we are also unable to give an accurate answer. </ p> "<p> <wbr> </ p> <p> New thematic interviews / reporter .Li Jian-</ p> <p> <wbr> </ p> <p> <wbr> </ p> <p> This special appreciated: </ p> <p> Jack red (China Agricultural University, Associate Professor .of food and nutrition) </ p> <p> Liu Ying-hua (PLA General Hospital nutrition practitioners) </ p> <p> Wang Ke (new approach to health development research center) </ p>.
