Chapter 15, Other food-related allergic disease entities

Abstract

Allergy to nonfood substances can be a cause of diet-related allergic symptoms. In the 2021 guidelines, a new chapter was created to address such disorders, including allergies to erythritol, cochineal dye, and Anisakis, as well as oral mites (commonly known as oral mite anaphylaxis or pancake syndrome). In this article, the concept, diagnosis, and lifestyle guidance for these diseases are reviewed. In particular, Anisakis allergy is an extremely common cause of anaphylaxis in adults, and should always be considered a cause of allergic symptoms after seafood consumption.
