Alternatively, medications with different side-chain structure are not cross-allergic. Cross-reactivity should not be assumed, and important foods should not be eliminated from the diet without appropriate testing and clinical diagnosis. Medications with identical or similar side chains may be cross-allergic. Cross reactivity means that a similar protein is present in a range of different foods. The most well-documented cross-reactivity occurs between apple and birch pollen however, individuals who are allergic to apple are not necessarily allergic to birch pollen. Cross reactivity can be difficult to predict without testing. If a person has a measurable reaction to a certain food with clinical diagnosis, avoiding similar foods that could trigger this reaction may be helpful. There are several types of hypersensitivity reactions, which are broadly divided into immediate and delayed reactions based on the time between administration and the appearance of signs or symptoms 1. This is a list of possible food and plant. A person allergic to a plant may be allergic to related foods. If someone is allergic to peanuts, for example, they might react to soya, peas, lentils or beans – food items in the same biological family (legume).Īllergic cross-reactions can also happen between certain fruit or vegetables and latex (known as latex-food syndrome), or the pollens that cause hay fever. Hypersensitivity reactions, or allergic reactions, are immunologic reactions to a drug. Possible Allergen Plant and Food Cross-Reactivity. Most adverse reactions to ASA, such as gastrointestinal intolerance, are predictable and are dose and host related. This means that someone may suffer an allergic reaction even when avoiding the foods they know they are allergic to. Reactions can be either light or heavy and are known as allergic cross-reactivity. Such reactions may be to different foods containing the same allergen, or to an allergen with a very similar protein structure. Allergy to eggs from duck and goose without sensitization to hen egg proteins. Abarro B, Seoane FJ, Vila C, Lombardero M. Allergol Immunopathol (Madr) 2020 48:265. Individuals who react to specific food allergens, inhalants or substances can develop an allergy to others. The frequency of cross-reactivity with various avian eggs among children with hen's egg allergy using skin prick test results: fewer sensitizations with pigeon and goose egg.
