Oral Food Challenges & Relationship to Allergen-Specific IgE Levels

Diagnosis of food hypersensitivity is a clinical challenge and the only current definitive test is the Double Blind Placebo-Controlled Food Challenges. Although the Double Blind Placebo-Controlled Food Challenges is the current gold standard, it is difficult to perform and is very time-consuming. Hence, researchers are continually evaluating new tests and assessing the value of the available serum tests. (more…)

Gastrointestinal Allergy Symptoms and Food Intolerance

gastrointestinal allergy symptoms
Gastrointestinal allergy can be classified according to the triggering antigen, the mechanism of immune reaction, or the anatomic site of reaction.

Gastrointestinal allergy may be triggered by food components (e.g. food proteins or glycoproteins), and by other antigen antibody reaction to (e.g. bacterial disease, viral, fungal, and worm antigen), drugs and chemicals, (more…)

Oral Allergy Syndrome: Symptoms, Mechanisms, and Reactivity

oral allergy syndrome symptoms
The oral allergy syndrome is difficult to detect. Common allergy tests to examine allergy are using extracts only in skin scratch testing. But this method is quite useless due to many enzymes involved in allergy reaction are already broken out in the process of extraction. They are not as effective as the original enzymes. Oral Allergy Syndrome is usually diagnoses by symptoms that are appeared. The other method is to look for allergy history to pollen, if any. (more…)

Antibodies in Food Sensitivity – IgG Antibody

antibody food sensitivity
It is common to find anti-food IgG antibodies circulating in blood, even in people who have no signs or history of adverse reactions to foods. In fact, some authorities think that an increase in anti-food IgG in some cases might be indicative of successful resolution of an IgE-mediated allergy. The subject of IgG-mediated food allergy is extremely complicated because of the nature of the antibody and the immunological reactions associated with it. The present knowledge about food allergy-associated IgG may be summarized as follows: (more…)

Dietary Management of Oral Allergy Syndrome

oral allergy syndrome
Oral allergy syndrome is one form of allergy that body have allergic reaction to fruits and vegetables. Based on statistics facts, The American Academy of Allergy Asthma and Immunology described that probably one third of people allergic to pollen may can extend and develop to oral allergy syndrome. As a matter of fact, not only pollen and fruits allergy are related, but pollen allergy can lead into the oral allergy to certain fruits and vegetables. (more…)

Management Food Associated Asthma in Children | Asthma Foods to Avoid

asthma foods avoid
After long-term avoidance of the offending foods, many children outgrow their food allergies. Subsequent periodic challenge with asthma foods to avoid, the offending food should therefore be undertaken to determine whether your child remains allergic to it. The results of skin and blood tests tend to remain positive long after symptoms have resolved, so direct challenge with the offending food is usually necessary. (more…)

Oral Tolerance and Antigenic Proteins Founds in Food

gut-associated-lymphoid-tissueHuman body treated all of the food that we ate, either plants or animals, as foreign substances. It is body immune system’s function to protect us from foreign material’s intrusion which may causes harmful to us. Then why does our immune system not oppose and refuse foreign materials that we consume as food?”

Naturally, if our body totally reject those foods which get into our body, we could not survive! Then, what is it that allows for food to plainly evade the roadblock of immune cells and be taken up into our bodies? In the final process, food become an integral part of our tissues and organs, and then be used as fuel for essential body processes. Research has begun to reveal part of the answer to this important issue in our body complex immune system question: the complex series of events known as oral tolerance. (more…)
