![]() Management and prognosis of oral allergy syndrome (pollen-food allergy syndrome). In: UpToDate, Post, TW (Ed), UpToDate, Waltham, MA, 2018.Īdkinson, N. Nowak-Węgrzyn, A. Clinical manifestations and diagnosis of oral allergy syndrome (pollen-food allergy syndrome). In: UpToDate, Post, TW (Ed), UpToDate, Waltham, MA, 2018. Includes berry (strawberry, blueberry, raspberry, etc), citrus (orange, lemon, etc), grape, mango, fig, peanut, pineapple, pomegranate, watermelon.Possible cross-reactions (to any of the above pollens) Includes banana, cantaloupe, cucumber, honey dew, watermelon, zucchini, echinacea, artichoke, paprika, honey Potential reaction: Dandelion, hibiscus or chamomile tea.Includes carrot, celery, coriander, fennel, caraway, parsley, peppers, black pepper, sunflower, garlic, onion, mustard, cauliflower, cabbage, paprika, lychee, broccoli.Includes fig, melon, potato, tomato, orange, Swiss chard, kiwifruit.Includes almond, apple, celery, cherry, hazel nut, peach, pear, parsley. ![]() Potential reaction: almond nut and walnut.Includes hazelnut, apple, avocado, peach, pear, peanut, apricot, carrot, celery, cherry, chicory, coriander, fennel, fig, kiwifruit, nectarine, parsley, parsnip, peppers, plum, potato, prune, soy, wheat.Importantly, not all the foods listed below will cause reactions for any one individual: If such symptoms are noted, evaluation by a board-certified allergist/immunologist is recommended.Ĭross reactions have been described for the following foods. Symptoms with peanut, tree nuts and soy may be the initial manifestations of a more serious food allergy with potential for anaphylaxis. See below for list of pollens and the foods that they cross react with. Individuals may have more food sensitivity during the season when relevant pollens are elevated in air. Some researchers report that Oral Allergy Syndrome can improve with allergen immunotherapy (allergy shots). Symptoms typically resolve without treatment. An epinephrine device is usually not necessary, because this type of allergy is unlikely to progress to anaphylaxis. The cooking process usually changes the protein enough so that one can tolerate the food without symptoms. Also, once swallowed, the stomach juices and enzymes degrade the protein rendering it harmless. The most common symptom is an itching or burning sensation in the lips, mouth, ears, or throat upon eating fresh or raw fruits and vegetables. Oral Allergy Syndrome can occur in people with seasonal pollen allergies (hay fever) and is due to cross-reactivity between certain foods and pollens. ![]()
