Food Allergens

Food Allergy is one of the most common allergies that affect men and women regardless of age. It is the condition in which the immune system overreacts to some food substances or their ingredients, triggering the production of antibodies to eliminate the threat. Allergies can be inherited or acquired. Individuals may also develop an allergy to a particular food to which they have not been allergic in the past. Common food allergie includes shellfish allergy, dairy allergy, fruit allergy, etc. Correct diagnosis and complete avoidance of the allergic substance are key to preventing anaphylaxis.

Signs and Symptoms of food allergy:

Usually, upon ingesting the allergic food, the symptoms and signs begin. However, the severity of the symptoms varies from person to person depending upon the immune response. The common symptoms include mouth itching, hives, difficulty swallowing,  breathlessness, abdominal pain, nausea and vomiting, dizziness, diarrhea, itchy and watery eyes, angioedema and hay fever. Some individuals develop anaphylaxis with sudden onset of respiratory distress, chest congestion, swollen tongue, and coma.

In the case of a food allergy, the immune system of the affected person reacts to normally harmless foods with an excessive defensive reaction. The body forms defensive antibodies, mostly IgE, against certain protein components called allergens. Why the immune system in some people reacts exaggeratedly to certain food components has not yet been precisely clarified. In addition to environmental factors, hereditary probably also play a role here.
In IgE-mediated food allergies, allergic symptoms usually occur within a few minutes to two hours. The location of the reaction and how strongly they occur varies from person to person. Reactions often take place on the mucous membranes, for example in the form of inflammation of the intestinal mucosa, watery and swollen eyes, runny nose, sneezing, coughing, or asthma attacks with shortness of breath. In addition, skin rashes, eczema, wheal formation, and itching as well as diarrhea, nausea, or flatulence often occur with a food allergy.
The prevalence of food allergies is reported to range from 1 to 10% of the total population and depends on multiple factors. The dietary behavior in various countries plays a decisive role. Certain types of food trigger these allergies more often than others. These include nuts, wheat, milk, seafood, soy, and chicken eggs.
A blood test indicates whether the body has produced specific antibodies, predominantly IgE antibodies. In a skin test, a solution containing food protein is applied to the lightly scratched skin and observed to see whether it turns red or itchy wheals appear. If an allergy is detected, the most important treatment is to avoid the triggering food. In case of severe allergies, an emergency kit with epinephrine injection, antihistamine, and cortisone tablets is necessary, which can be applied in case of anaphylactic reactions.
Central BioHub provides thousands of serum samples isolated from consented donors and indicated for in-vitro biomedical research. The biospecimens are tested for sIgE for different food allergens and stored at <-18 °C at our biobank. Positive tests are arranged into four groups, the so-called RAST classes, of which class 1 represents the lowest and class 4 the highest content of specific IgE.
