Food cross reactivity chart3/15/2023 Considerations for an approach to individual patient care are highlighted.Ĭopyright © 2020 American Academy of Allergy, Asthma & Immunology. The complicating factor of addressing co-allergy, for example, the risks of allergy to both peanut and tree nuts among atopic patients, is also discussed. This review discusses clinically relevant cross-reactivity related to the aforementioned food groups as well as seeds, legumes (including peanut, soy, chickpea, lentil, and others), tree nuts, meats, fruits and vegetables (including the lipid transfer protein syndrome), and latex. 1 1.PDF Oral allergy syndrome pollens and cross-reacting foods 2 2.Food Allergies and Cross-Reactivity 3 3.Oral Allergy: Plants, Foods That Cross-React. Low rates are noted for grains (wheat, barley, rye), and rates of cross-reactivity are variable for most other foods. Examples of food families with high rates of cross-reactivity include mammalian milks, eggs, fish, and shellfish. Although molecular diagnostics have improved our ability to identify clinically relevant cross-reactivity, the optimal approach to patients requires an understanding of the epidemiology of clinically relevant cross-reactivity, as well as the food-specific (degree of homology, protein stability, abundance) and patient-specific factors (immune response, augmentation factors) that determine clinical relevance. 2 People with sesame allergy should talk with their physicians about which other food they may need to avoid. However, many are sensitized to foods without exhibiting clinical reactivity. There also appears to be cross-reactivity between sesame allergens and rye, kiwi, poppy seed, and various tree nuts (such as hazelnut, black walnut, cashew, macadamia, and pistachio). This results in patients having allergic sensitization (positive tests) to many biologically related foods. The diagnosis and management of food allergy is complicated by an abundance of homologous, cross-reactive proteins in edible foods and aeroallergens.
