Food allergy

Classic IgE food allergy

A classic type I allergy is when the immune system produces specific IgE antibodies (subclass E immunoglobulins). These antibodies cause an immediate allergic reaction. Symptoms appear within seconds or minutes: severe swelling, difficulty breathing, rash, itchy skin or even anaphylactic shock.

A person with a type 1 allergy is likely to know which food is causing the problem because the symptoms appear immediately. Therefore, blood tests are not necessarily needed to detect this type of allergy. IgE tests are mainly done for confirmation. The ROLE™ program does not detect type I food allergies.

Delayed IgG food allergy

Type III food allergy is when the immune system produces specific IgG antibodies (subclass G immunoglobulins). These antibodies can cause inflammatory processes. Symptoms appear up to three days after consuming the trigger food.

Because of the delayed onset, it is very difficult to determine which food is causing the problem.

With the ROLE™ program, you only need to avoid foods with elevated IgG antibody values. This means you can maintain a versatile and varied diet and not have to restrict yourself unnecessarily. After a certain period of avoidance, you can reintroduce foods one at a time into your diet and monitor your symptoms. This provocation phase is an important step in identifying your personal “trigger products”.
