What is the difference between IgG and IgE?

IgG stands for “Immunoglobulin G”. These are the antibodies found in the human blood. They are used by the immune system to identify, neutralize, and destroy foreign objects, such as bacteria and viruses, or other large foreign molecules. Everybody has IgG antibodies, but occasionally they start to react against foods. This is what can cause food allergies or delayed-onset food allergies (food hypersensitivities, commonly also known as food intolerance). IgE mediated allergies (type I) are completely different from IgG mediated allergies (type III). An IgE allergy is a traditional “true” allergy, its symptoms occur immediately and remain for your whole life. IgG food allergies occur delayed and may decrease or disappear if the change in diet according to the ImuPro results is strictly followed. For this change the IgE findings must be taken into account and the respective food must always be avoided.
