QUINCE ALLERGY
Key Allergens
Quinces are fruits from trees in the Rosaceae family of plants. Other plants in this family include almond, apple, plum, peach and pear.
Quince is not a commonly eaten fruit worldwide, but some studies have suggested it contains Lipid Transfer Protein (LTP). LTPs are panallergens which can case severe allergy over large groups of seemingly unrelated groups of foods.

Food Intolerances
Quince 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.
Like apples and pears, quince are 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 quince allergy with allergic symptoms to 3 or more of the foods mentioned in cross reactivity section.
Cross Reactivity
Other plants in the Rosaceae family of plants include almond, apple, apricot, blackberry, cherry, peach, pear, plum, raspberry and strawberry.
