Various additives, including food colorants (FCs), are used in the food industry to make food appealing to consumers and to add variety. Despite the widespread usage of FCs, adverse reactions related to their consumption, including reactions triggered by immune (immediate and delayed-type hypersensitivity) and non-immune (intolerance) mechanisms, are considered rare. There is a discrepancy between the perception of patients and parents (7.4%) and the reported prevalence of adverse reactions to additives (0.01-0.23%), which is higher in atopic individuals (2-7%). Documented reactions are mild, involving mainly the skin, and, rarely, anaphylaxis. A major problem in diagnosing reactions to FCs is identification of the offending agent(s), which is based on careful dietary history taking. Allergy testing is usually unrevealing, except for reaction to some natural colorants. Treatment consists of avoidance of the offending colorant as no successful desensitization procedures have been reported. Crown Copyright (C) 2017 Published by Elsevier Ltd. All rights reserved.
