Many people have trouble distinguishing whether or not they are allergic to certain foods or they have increased sensitivity or intolerance. Food allergy and sensitivity testing can be performed at home by the help of various kits that are available on the market. Food allergy testing kits will help you determine common foods that negatively stimulate your immune system and test the sensitivity. The most common mistake is that, often, people tend to confuse food sensitivity to food allergies.
Allergy and intolerance (sensitivity) difference
Allergic reaction is a result of your immune system wrongfully attacking a protein which exists in various food products. When such protein enters the human body, the immune system creates an antibody which is called immunoglobulin E (IgE). The main purpose for this antibody is to destroy the so called intruding protein.
Food intolerance is an unwanted body reaction too (as is allergy). However, the difference is that food allergy is caused by immune system and food intolerance is caused by digestive system. In this case, antibodies are not involved in negative reactions regarding food intolerance. Certain food products are hard to digest because of lack of digestive enzymes. Also, food intolerance might be caused by various chemical compounds like lactose. For example, we call people lactose intolerant when the enzyme that breaks down lactose (milk sugar) is missing.
How fast do food allergy and food intolerance reactions appear?
Usually food allergic reaction might appear very quickly, no later than two hours after eating allergenic food. Food intolerance reaction, on the other hand, are slow and symptoms might only be visible in a couple of days.

Food Allergy, Intolerance and Sensitivity Testing
You can perform food allergy and sensitivity and other various food intolerance tests in health institutions and medical centres.
Perform food sensitivity testing by writing a food journal and eliminating food products one by one. For example, write down the symptoms that you are suffering from like abdominal cramp, exhaustion, joint pain and others. Then, each week eliminate a food product like eggs or dairy and see if the symptoms are still there. If they are still persistent, eliminate products that have gluten and continue to observe.
