Why does trigger food have to be avoided for a whole year?

First of all the IgG has to be eliminated so that you can eventually start eating these foods again – at least now and then in small quantities as part of your rotation diet. This can only be achieved through a strict avoidance for at least a year. After this you can check in another provocation phase if this food still triggers symptoms.
