COFFEE ALLERGY


Key Allergens

There are 3 allergens associated with coffee allergy. Cof a 1 is a chitinase protein. Chitinase proteins are usually associated with Latex Food Syndrome, but in this case the allergen is an inhalant allergen and not a food allergen, so does not need to be avoided if suffering from this syndrome.

Cof a 2 and Cof a 3 are both metallothionein proteins. Again these are inhalant allergens and not food allergens and they are used in the plant to bind metals such as zinc.


Food Intolerances

Food is low in FODMAP Food is moderate in salicylates

Coffee is a low 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.

Coffee beans are moderate in salicylates (but decaffinated coffee is considered to be low). Salicylates have the potential to cause gastrointestinal food intolerance symptoms in people who are sensitive to salicylates.<

Associated Syndromes

Allergy to chitinase proteins has been linked to Latex Food Syndrome.

Coffee allergy has been linked to asthma, rhinoconjunctivitis and atopic dermatitis, especially in patients who work with coffee occupationally.

Cross Reactivity

Other foods containing chitinase proteins are chestnuts, banana, avocado, pomegranate and maize. Other plants containing chitinases which are considered to be inhalant allergens are cockroaches and dust mites.
