Raspberries are part of the Rosaceae family of plants, many species of plants in this order are cultivated for their fruit, including apples, cherries, pears and almonds.

The two main allergens identified in raspberry are Rub i 1 and Rub i 3.

Rub i 1 is an allergen in the Bet v 1 family, which can cause oral allergy syndrome.

Rub i 3 has been identified as a Lipid Transfer Protein (LTP), but is not commonly linked to LTP Syndrome.

A study from 2008 showed raspberries contain chitinase proteins. These are proteins associated with Latex allergy.

Raspberries are 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.

Raspberry is a food high in salicylates. Salicylates have the potential to cause worsening of asthma, swelling, itching and hives as well as 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 Pollen-Food Allergy Syndrome if you suffer from raspberry allergy with oral allergy symptoms to 3 or more of the foods mentioned in cross reactivity section.

You may have LTP Syndrome if you suffer more severe allergic reactions to multiple foods mentioned in the cross reactivity section.

An allergy to chitinase is linked to Latex Food Syndrome. Which is when a person is sensitised to latex through contact and later has oral allergy type reactions to food which contain similarly shaped proteins.

If sensitised to birch tree pollen you may have Pollen Food Allergy Syndrome and may also react to apple, kiwi, pear, peach, plum, nectarine, apricots, cherries, tomato, celery, carrot, potato, parsnip, pepper, dill, cumin, peas, coriander, fennel, hazelnut, walnut, almonds, peanuts, lentils and beans

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.

Chitinases are also found in avocado, banana, cashew, chestnut, coffee, corn, grape, kiwi, mango, passion fruit, plantain, pomegranates and spinach.
