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.
Quince is a high FODMAP food. FODMAP
stands for F
olyols. 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.
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.
Other plants in the Rosaceae
family of plants include almond, apple, apricot, blackberry, cherry, peach, pear, plum, raspberry and strawberry.
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, pear, wheat and maize.
These food lists are not exhaustive, the most up to date information is on the Cross Reactivity Tool.
