Adverse reactions to ingested foods, synthetic food additives and drugs can by elicited by a variety of pathomechanisms. Clearly toxic reactions have to be differentiated from immunologically (allergy) or non-immunologically (intolerance) mediated adverse reactions. When the observed symptoms of toxic or intolerance reactions mimic the typical symptomatology of IgE-mediated reactions, the term "pseudoallergy" is used. The diagnosis of both, allergic and pseudoallergic reactions, is based on the anamnesis with an analysis of pharmacological and immunological food properties, food additives and drug intake. Skin tests and specific serum IgE evaluation are informative in allergic reactions only. Natural foods, food additives and drugs may be tested according the priniciple of placebo controlled challenge tests. Individually performed eviction regimes are the principal methods of prevention.
