This review provides a comprehensive listing of common and less common allergenic foods in a tabular form. Where available, information from double-blind, placebo-controlled food challenge trials are presented for the less common allergenic foods, as these studies represent the most objective diagnostic approach to establish a cause-and-effect relationship between ingestion of a food and an allergic reaction. Also, information relating to results of skin tests, immunoassays and histamine release tests are presented for the less common allergenic foods.
