Why Does An Allergy Occur And When Should You Get A Food Allergy Testing Done?
Some people can go through life enjoying just about the very same foods that trigger deadly allergies in others.
Why? The answer lies in the antibody response. IgE antibodies when triggered, cause the release of various vasoactive compounds causing characteristic allergy symptoms.
Allergenicity is the property of a particular protein in the food to cause this reaction in the systems of the body. During the digestion process, proteins too undergo some change in order to either be absorbed or excreted. This ability of theirs to pass through and remain intact is what plays a role in their ability to cause allergies. When the protein binds to IgE antibody, an allergic response is seen.
