¤e present guideline updates and summarizes S1- and S2-guidelines published by the German Asso-ciation of Scienti—c Medical Societies (Arbeits-gemeinscha¥ der Wissenscha¥lichen Medizin ischen Fachgesellscha¥en, AWMF) which have been pub-lished on various aspects of food allergy [1, 2, 3, 4, 5, 6, 7]. It ful—lls the methodological requirements set out by the AWMF on the development of guidelines for diagnosis and treatment and represent S2k-guide-lines according to the AWMF three-level concept. DELBI criteria were taken into account [9]. ¤e strength of recommendation for the individ-ual recommendations is expressed in the guide-lines using standardized formulations (Tab. 1) [10].¤e guideline is based on the current European Academy of Allergy and Clinical Immunology (EAACI) S3-guideline on the diagnosis and treat-ment of food allergy [11], as well as on systematic EAACI reviews [12, 13] from 2014, for which sys-tematic literature searches of PubMed, meta-analyses, clinical studies, and other scienti—c investigations
were undertaken. Consensus on the present guide-line was achieved independently from the Euro-pean guidelines by an interdisciplinary panel of German-speaking experts who were nominated by the participating societies.
