At War With Food: The Cause of Food Allergy

An allergy takes place when the immune system suddenly has an abnormal response to a certain material that is usually not detrimental to most individuals except those who have allergies. When an allergy is triggered by a substance or allergen, a persons body recognizes this as a trespasser and subsequently releases chemicals to fight off the trespasser causing symptoms that can range from a simple irritation to a fatal reaction that may even lead to death.

Food allergy is a reaction made by the immune system in which antibodies are produced by the body as a result of a negative effect to some foods. Though there are many individuals who claim that they have food allergies, there are only a few who really have certain allergic reactions to food. Most people confuse food allergy with food intolerance. Food intolerance and food allergy are both sensitivity reactions to food, but intolerance to certain types of food does not affect the immune system and isnt really a life threatening incident.

As of the present time, the medical world still has not found any cure for food allergies. Allergy management only involves the prevention of intake of food allergens and some diet modifications.

Looking closely, during an allergic reaction, the bodys immune system releases antibodies, specifically immunoglobulin E. It subsequently causes the production of chemicals like histamine in the process of protecting the body. Now, these chemicals are the root cause of symptoms which may include an irritation in the eyes, skin, throat, lungs, and the gastrointestinal organs. These takes place whenever the individual is exposed to the allergen.

Although any type of food can cause allergic reactions to different types of individuals, there are eight major foods out there that are often the main culprits of an allergic reaction. These eight major allergy-causing foods are: fish, soy, milk, wheat, eggs, peanuts, tree nuts, and shellfish.

By and large, individuals afflicted with allergies react only to some allergy-causing foods. Sometimes, allergy to a certain type of food may also cause allergic reaction to foods that may be related with the allergen food. This incidence is known as cross-reaction. For instance, an allergic reaction to wheat may also cause a reaction to rye. Allergy to pollens subsequently causes an allergy to green apples, hazelnuts, almonds, and peaches. A reaction to goats milk may also be associated with an allergy to cows milk. And the list goes on and on.

Moreover, individuals who have been afflicted with asthma and/or eczema may also be at risk of developing a food allergy. With bad luck, they would probably have a reaction that is more severe than those people who only have food allergy to worry about. This is due to the fact that when an allergy takes place the person will be under stress which then may lead to triggering their asthma and/or eczema which will aggravate the situation.

But the intensity of the reaction will depend on some circumstances like the individuals sensitivity threshold to the food allergen, amount of eaten food, and the exposure scale the person has to the food.

Although, there is no cure to allergies, self-discipline and vigilance will help you, the allergy-sufferer, overcome these food problems. There may be some medications out there that alleviate the symptoms but a consultation to the physician will give you a better understanding to your allergy problems as well as treatment recommendations.

Spotting the Culprit: Food Allergy Blood Test

A simple food allergy can change the way a person live his or her life for it basically makes this person a little altered than his or her allergy-free contemporaries. Allergies with certain types of food are caused by a specific chemical that is a common chemical ingredient in that same food. So, it is not surprising that an allergy to food may also cause a reaction to medications which subsequently leads to an alteration in medications, too.

As a result, medical professionals have been finding ways to detect food allergies as early as possible before the reactions take place. There are numerous testing processes that they utilize in finding out whether a patient is allergic to certain types of chemicals. One of these tests includes blood testing.

But before going further about blood testing, you should first understand what goes on inside the body during the allergic process.

There are two ways that the immune system reacts to an allergy. One approach is that the body, after the detection of allergens, generates immunoglobulin E or IgE which is a kind of antibody. IgE is then disseminated in the blood stream. The other approach is the occurrence of mast cells. Mast cells appear in the body tissues particularly in common allergy sites like the throat, nasal cavity, oral cavity, skin, lungs, and the organs of the gastrointestinal system.

There are cases that the capacity to produce immunoglobulin E to fight off a certain food allergen is in inherited. Individuals who are at higher risk in being afflicted with food allergies are those who have blood relations who have suffered from asthma, eczema, and hay fever.

Furthermore, an individual must initially be in contact with the potential food allergen before his or her body produces the antibody IgE. As the individual is finally exposed to the allergen the IgE is then produced and consequently fastens itself to the mast cells. This team up will eventually cause body chemical reactions the next time the allergen is eaten by the hapless individual.

Now, this immunoglobulin E is important in the detection for allergies through blood testing. The most frequently utilized blood tests are Radioallergosorbent test (RAST) and CAP-RAST (which is basically similar to RAST but more advanced).

In blood tests, the outcome is ranked from one to six, with one the least positive and six the most. Blood tests can be utilized in individuals afflicted with a severe case of eczema since this type of testing can not be influenced by antihistamines.

Following the drawing of blood samples, it is then sent away to the laboratories for further evaluation. Blood tests can be pretty much expensive and results are not immediately available for the patient to know whether they are allergic to certain food or not.

Eventually, an allergy is diagnosed when the medical professionals detected the presence of the immunoglobulin E or IgE in the patients blood. But the results of the blood test can not identify if there is a close connection between the existence of IgE and the allergys intensity. There are even cases wherein the results are negative although the patient manifests symptoms of food allergy.

In case, blood tests fail there are still other tests that the medical professionals may utilize to size up your allergy. These tests may include skin prick tests, elimination diets, and food challenges.

Furthermore, feel free to ask questions to the medical professionals concerning the results to better understand your condition.

Food Allergy and Anaphylaxis in an Irritating Nutshell

A person will never know if they are allergic to a certain type of food unless they have eaten the food allergen itself. It takes a certain amount of food for the reaction to take place and trigger a symptom.

Food allergy and anaphylaxis are closely related, but they have their own defining differences that will be discussed as you read on.

Plus, a person can also develop allergic reactions to foods that are closely related to the original food allergy he or she has. Say, an allergy to oysters can also lead to an allergic reaction when the person eats shrimp, crabs, or fish.

In food allergy, the individuals immune system reacts in two ways. The body may respond through the use of mast cells. These mast cells can come about at just any part of the human body but its favorite spots make itself known to the world is in the throat, lungs, eyes, skin, and especially the organs of the gastrointestinal system. The other type of response is through the bodys release of immunoglobulin E antibodies that travel through the blood system. It then eventually causes the discharge of the body chemical histamine which then causes the activation of allergic reactions in the common body sites previously mentioned.

On the other hand, anaphylaxis is derived form the Greek words ana and phylaxis, which subsequently means back and protection. It is the abrupt allergic response that is much more intense than the common allergy which can be lethal to the sufferer. Chief causes of anaphylaxis include insect stings, skin contact to latex, medications, and food. Anaphylaxis may also be idiopathically caused or, in lay mans terms, unknown causes.

Like in food allergy, anaphylaxis involves the reaction of the different body sites; the only difference is the intensity of the response and only a small amount of the allergen is needed for the reaction to take place. The time span before signs and symptoms become evident ranges from within a few seconds up to a few hours after allergen exposure.

Anaphylaxis can come about following the intake of food, skin contact, or even as simple as inhalation of the food aroma. The life threatening type of anaphylaxis is called anaphylactic shock. In anaphylactic shock, only a tiny amount of the food allergen is needed to cause death to the sufferer within moments of exposure.

Individuals who are in danger of undergoing an anaphylactic reaction are those who have a history of allergy to food, asthma, and eczema. They are more likely to experience an anaphylactic response that can be fatal. Another population group who are also at risk of anaphylaxis, through the evidences of current studies that have been conducted, is teenagers who are afflicted with a certain type of food allergy. This is due to the fact that teenagers have frequent tendencies to eat out, are daring and experimental in their endeavors, and are more likely to fail to identify symptoms of anaphylactic reaction. Moreover, teenagers have tendencies to forget to carry with them essential medications which can either be caused by self-consciousness common to their age group.

Symptoms of anaphylaxis may be similar to that of food allergies. Basically, an incident of anaphylaxis initially starts with an itchy or irritating sensation, and some individuals experience a metallic after-taste. Anaphylactic symptoms may also include hot flashes or sudden warm feeling, inflammation of the throat and oral cavity, hives, dyspnea or labored breathing, low blood pressure, diarrhea, gastric irritations, and fainting or loss of consciousness.

Furthermore, there are cases wherein the symptoms fade away for a moment but then come back within a few hours; this incidence is known as biphasic reaction.

To prevent food allergy and anaphylactic reactions, careful scrutiny of food labels, diet modifications, specific instructions in food orders in restaurants, and certain medications can be of great help in reducing the incidence of any type of reaction. Moreover, a consultation to the physician is advisable for an efficient management plan and if allergies seem to run in families because it can also be hereditarily caused.
