ASPARAGUS ALLERGY


Key Allergens

Asparagus is in the family Asparagaceae which also includes plants like yuccas and agave plants.

Aspa o 1 is the key allergen associated with an allergy to asparagus, it is a Lipid Transfer Protein (LTP). If you have an allergy to this protein you will still suffer symptoms on ingestion of the cooked vegetable.

There is some evidence that asparagus can cause contact dermatitis rashes - this is due to a plant growth inhibitor called 1,2,3-Trithiane-5-carboxylic acid which is present in young shoots. If sensitised to this you will still be able to eat the cooked food.

Food Intolerances

Food is moderate in sulphites Food is low in salicylates Food is high in FODMAP

Asparagus is naturally moderate in sulphites. This is a food intolerance which is more common in asthmatics. An improvement in symptoms can be made with a change to a low sulphite diet.

Asparagus is a high FODMAP food. FODMAP stands for Fermentable oligosaccharides, disaccharides, monosaccharides and polyols. Foods high in FODMAPs can cause symptoms of food intolerance, affecting the gastro intestinal system and this can be mistaken for a true IgE food allergy.

Asparagus is a food low in salicylates. Salicylates have the potential to cause gastrointestinal food intolerance symptoms in people who are sensitive to salicylates.

You can read more about Food Intolerances on the dedicated Food Intolerance Page.

Associated Syndromes

You may have LTP Syndrome if you suffer from asparagus allergy and other foods mentioned in cross reactivity section.

Cross Reactivity

Common foods involved in LTP allergy include kiwi, strawberries, sunflower seeds, walnut, apple, mulberry, banana, pea, apricot, cherry, plum, almond, peach pomegranate, raspberry, tomato, grape, celery, peanut, asparagus, cabbage, broccoli, chestnut, lemon, tangerine, orange, hazelnut, lettuce, lentils, lupin, green bean, pear, mustard, wheat and maize.
