...Food allergies affect around 4% of adults and 4-6% of children in the United States. The most common allergic reactions to food are cough, runny nose, sneezing, dizziness, chest pain, rashes, itching, hives, swelling, nausea, vomiting, and diarrhea. Factors that influence food allergies include exposure as a child and breast feeding. Allergic responses can arise from a number of proteins found within any given food. There are thought to be two types of allergic reactions, immune reactions and non-immune hypersensitivity reactions. Biosignaling plays a major part in the immune reaction response to food allergies. When cells receive and act on signals sent throughout the body, they are communicating through biosignaling. These are the signals that will bring about a response. Intolerance of certain foods creates a reaction within the cells of the body and there are many different kinds of biosignals that can result. They include ligand-gated ion channels, receptor enzymes, g-protein coupled receptors, and steroid receptors. In food allergy reactions the most common type of biosignaling reaction would be receptor enzymes. Within this process the enzymes demonstrate specificity, amplification, adaptation and integration. Enzymes and signal molecules will fit in a binding site on a complementary receptor; in food allergies certain responses will bind to the site and produce a reaction. The enzymes can also activate a large number of molecules, therefore demonstrating...

...In America, food allergies are estimated to affect four to six percent of children and four percent of adults (“Food Allergy”). This sounds like a small amount, but it alters the life of millions of people each day. Many children show signs of an allergic response to a particular food at a young age after trying it for the first time. The research of severe food allergies allow doctors to find the best treatment possible and work towards preventing allergic responses. People with food allergies are affected when eating foods that most can tolerate without a problem. More than one hundred seventy foods are known to cause food allergies, but the most common allergenic foods, referred to as “The Big Eight” are the following: eggs, fish, milk, tree nuts, peanuts, shellfish, soy, and wheat (Riddle). These account for ninety percent of all reactions (“Food Allergies”). The...

...Food allergy develops when the body‘s immune system wrongly reacts to a specific food as if it was a harmful substance in the body. The severity of a food allergic reaction differs in different people and can as well be different in the same person during different times. Food allergies are prevalent in young children. It is estimated that five to eight percent of all children suffer from food allergies. These allergies usually appear mainly in the early life of a child and present themselves in the form of facial swelling and itchy rashes, which appear shortly after ingesting food. However, food allergies may lead to severe allergic reactions involving diarrhea, breathing difficulties or vomiting and they are the common dominant triggers of anaphylaxis in children. Anaphylaxis is considered as the extreme form of an instant allergic reaction and can be life-threatening, even leading to death. The most common causes of allergic food reactions in children include cow’s milk, peanuts, and chicken eggs. Over the years as a child grows, they often outgrow chicken eggs and cow’s milk allergic reactions as they disappear after a few years. However, children do not outgrow allergic reactions from peanuts. Those who suffer from peanut allergy must follow a strict diet in their entire lives and carry medication with them always....

...Food Allergens An allergy is used to describe a response, within the body, to a substance, which is not necessarily harmful in itself, but results in an immune response and a reaction that causes symptoms and disease in a predisposed person. All food allergies are caused by an immune system malfunction. The immune system identifies certain proteins as harmful, triggering the production of immunoglobulin E (IgE) antibodies to neutralize the proteins known as allergens. Allergens are organic compound that contain hydrogen, oxygen and nitrogen, which form an important part of living organisms. Allergens contain protein, which is often regarded as a constituent of the food that we eat. For these to cause an allergic response they need to be bound to a protein once they are in the body. An allergic person’s immune system believes allergens to be damaging and so produces a special type of antibody (IgE) to attack the invading material. This leads to other blood cells to release further chemicals (including histamine), which together cause the symptoms of an allergic reaction. The most common symptoms are: sneezing, runny nose, itchy eyes and ears, severe wheezing, coughing, shortness of breath, sinus problems, a sore palate, swelling, sickness, vomiting, diarrhea and nettle-like rash.Almost anything can be an allergen for someone, but the most common are: wheat, soy, milk, eggs, nuts, tree nuts, fish, shellfish and other, like sulfites, which are food intolerances and...

...For more than a decade, peanut allergies in children have tripled in the United States. These dangerous allergies are causing harmful anaphylactic reactions that can lead to death. In 2008 a research team discovered that 1.4% of children had a peanut allergy, more than three times the 0.4% rate back in 1997. (Hendrick, 2010) This is an alarming rise that should not be ignored. The question is, why is this happening? I believe that the recent spike in peanut allergies is partly due to the excessive cleanliness during a child’s developmental years in our society. This phenomenon is known as the Hygiene Hypothesis, which was first introduced by Dr. Erika Von Mutius. During the 1990’s she compared the rates of allergies and asthma in East and West Germany. Before these two places were unified, East Germany was poorer and less hygienic than their neighbors to the West. Dr. Von Mutius hypothesized that the children growing up in East Germany would suffer from more allergies than the children in West Germany. To her surprise she found that it was actually the opposite! As a result from her studies, the Hygiene Hypothesis was born. (PBS, 2001). The Hygiene Hypothesis states that due to our relatively clean lifestyle, our bodies do not need to fight as many germs and bacteria as we did in the past. This results in a shift from fighting infections, to developing allergic reactions. (McMorris, 2007) With the development of antibiotics and the increased emphasis on using products such as...

...expect to have more children affected by allergies, a developing country such as Haiti or America? Despite expectations, in America, peanut and tree nut allergies encompass almost 90% of all food allergies, and the occurrence of peanut allergies in children has increased 21% since 2010 and is projected to increase in the future (American College of Allergy, Asthma, and Immunology, 2017). One explanation for this is the Hygiene Hypothesis; the idea that children in developing countries are exposed to more allergens in their environment, and are therefore able to develop more resistance to allergens, while American children are not exposed to many allergens (A. ElHag, personal communication, March 19, 2018). The environment and lifestyle...

...When I was thirteen years old I developed a gluten allergy. In the United States, over three million people are diagnosed with food allergies a year, and over 50 million people have a food allergy. So, even though it was hard to me to make this change in my life and it effected me in many ways, I was not the only person that ever had to go through it. However, there is a much smaller population of people that develop allergies later on in life. Roughly 6% of Americans are born with and food allergy and around 8% of people have an allergy by the time they are 12 years old, meaning that only 2% of people develop allergies around the age I did. When someone has an allergy there are many things they have to learn about it to keep themselves healthy....

...RATIONALE Childhood food allergies The purpose for my presentation is to inform elementary school staff of the signs and dangers with child food allergies. My presentation will provide education around the signs and symptoms of an allergic food reaction that could occur in the school. At the end of my presentation, the audience should be able to identify signs of an allergic reaction to food in order to have treatment begin in a timely/ effective manner for the child. Child care providers should be aware of the physical signs and symptoms of allergic reactions to food including anaphylaxis which is a life threatening condition. My intended audience is all staff, at all levels, working in the elementary school setting Knowledge will promote increased safety of elementary school children who suffer from food allergies. This is significant as nearly 8% of children have food allergies, with younger children affected most. Within this group, more than 15% of school aged children with food allergies have had a reaction while in school (U.S. Census Bureau, 2010) Approximately 20-25% of epinephrine administrations in schools involve individuals whose allergy was unknown at the time of the reaction. (Nowak-Wegrzyn A, Conover-Walker MK, 2001) Presentation Failure to promptly treat food anaphylaxis with epinephrine within minutes is a risk factor for fatalities, This potentially deadly disease affects 1 in every 13 children (under 18 years of age) in the U.S. That’s...

...people who are severely allergic to peanuts and peanut products. Did you know that one of the ingredients in some flavors of Jelly Belly jelly beans is peanut flour? Did you know that food, processed in equipment that has previously processed food containing peanuts, may be as lethal to the severely allergic as food containing peanuts? If your answer is No, then read on. Here is a story that sounds like something from Stephen King. True food allergies are rare. The FDA (U.S. Food and Drug Administration) estimates that only 2% of the adult population of the United States is allergic to foods. Further, only eight foods cause 90% of all food allergic reactions. They are milk, egg, wheat, peanut, soy, tree nuts, fish and shellfish (Food Allergy Network). Many reactions to foods are really intolerance (reaction of the metabolism due to a chemical deficiency) rather than allergy (reaction of the immune system). Many infant allergies, which are later outgrown, are thought to be the result of immature immune systems. However, other allergies become stronger as the person ages and inadvertently becomes more exposed. One report on KCBS radio indicated there may be a link between mothers who ate peanuts during pregnancy and their children’s subsequent allergies. One of the reactions to peanut allergies is anaphylaxis which is characterized by swelling of the mouth and throat, a feeling of panic or dread, followed by a drop in blood pressure, unconsciousness and death. I was on a...

...GROUP 4-Corn and Dairy Allergies in Mexico Traditional Dietary Habits; The traditional diet of Mexico and Central America is based on corn and beans, but offers a wide diversity of preparations. Coupled with locally available fruits, vegetables, meat and dairy products, the diet can be highly nutritious. However, poverty frequently limits access to an adequate variety of quality foods, resulting in malnutrition. With dairy and corn products being frequently consumed, they represent abundant cause for allergies, due to the proteins of their makeup. Allergies; A food allergy is an adverse immune response to a food protein.[1][2] They are distinct from other adverse responses to food, such as food intolerance, pharmacological reactions, and toxin-mediated reactions. The protein in the food is the most common allergic component. These kinds of allergies occur when the body's immune system mistakenly identifies a protein as harmful. Some proteins or fragments of proteins are resistant to digestion and those that are not broken down. In the digestive process are tagged by the Immunoglobulin E (IgE). These tags fool the immune system into thinking that the protein is an invader. The immune system, thinking the organism (the individual) is under attack, sends white blood cells to attack, and that triggers an allergic reaction. These reactions can range from mild to severe. Allergic responses include dermatitis, gastrointestinal and respiratory distress...

...The infants that cannot digest cow’s milk protein have problems in several organ systems showing more than one different symptoms in that organ systems (Isolauri 1997). These symptoms are mainly come from the gut, the skin and the respiratory tract (Hill, Firer et al. 1986). All the above can be referred as Cow’s Milk Allergy (CMA). CMA is an Immunoglobulin E (IgE)-mediated hypersensitivity reaction and it is a food allergy. The term food allergy describes the adverse immunologic response to a food protein (Waserman and Watson 2011). The protein content is what leads to the sensitization and allergy of humans. These proteins contain the allergenic segments which are between 10 to 70 kDa in size, water-soluble glycoproteins such casein in...

...Eczema Eczema, also known as dermatitis, is a disease that causes inflammation and irritation of the skin. In fact, that's what dermatitis means: derma means 'skin', and -itis means 'inflammation'. This irritation and inflammation of the skin can take on many forms, including swelling, rashes, pustules, and itching. Common causes for eczema include allergies, changes in hormone levels, stress, or genetic predisposition to the disease. While there is no cure for eczema, there are ways to treat it. Ointments and medicated salves can help sooth the symptoms, while prescription medications can help manage the dryness and irritation of the skin. Prevention is a best bet for eczema, including moisturizing the skin and avoiding irritants. Eczema affects the stratified squamous epithelium of the skin, and the underlying blood vessels. Causes & Triggers The exact causes of eczema are unknown. You might have inherited a tendency for eczema. You may have a family member who has eczema or who has hay fever (allergic rhinitis) or asthma. Many doctors think eczema causes are linked to allergic disease, such as hay fever or asthma. Doctors call this the atopic triad. Many children with eczema (up to 80%) will develop hay fever and/or asthma. There are many triggers of eczema that can make it flare or get worse. Below are some of the common triggers. You should learn what triggers your eczema to flare, and then try to avoid it. IRRITANTS: Irritants can make your symptoms worse. What irritates...

...ALLERGY TESTING Perennial allergies result from airborne substances that are present all-year-round such as house dust. This causes congestion, an itchy nose that may also run, and itchy mouth and throat. House dust may contain mould and fungal spores, fibres of fabric, animal dander, dust mites, and bits of insects. Cockroach particles are often the cause of allergic reactions. Because more time is spent indoors during cold times of the year, allergic reactions are likely to be more severe in the winter. Perennial allergies usually cause allergic rhinitis symptoms but rarely allergic conjunctivitis. Allergic conjunctivitis may develop due to substances being introduced into the eye, such as eye drops or cream used to treat eye disorders, cosmetics such as eyeliner, mascara or face powder, and hair dye. The cleaning solutions used to clean contact lenses may cause reactions. Antihistamines are given to relieve the symptoms, but the person may have to take them 12 months of the year. Anaphylactic shock is the most extreme form of reaction and it can be fatal in not treated medically immediately. Anaphylaxis develops suddenly, the face, lips, tongue and airways start to swell, cutting off respiration. Anxiety, tightness in the chest and difficulty breathing are also present. Blood vessels begin to dilate (widen) causing a severe drop in blood pressure, this may lead to unconsciousness and shock.
