RYE ALLERGY


Key Allergens

Rye is a grain in the Poaceae family of plants, other plants in this family include barley, corn, durum wheat, wheat, oats and rice.

There are 3 allergens associated with an allergy to rye. Two are airway allergens and one is a food allergy called Sec c 20 which a gamma secalin protein.

Secalin proteins are prolamins, storage proteins found in cereal crops which have the ability to trigger coeliac disease symptoms. Collectively these proteins are known as gluten.

Sec c 5 is a grass pollen allergen and Sec c 38 is dimeric alpha-amylase/trypsin inhibitor, both are pollen allergens.


Food Intolerances

Food is high in FODMAP

Rye 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.

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

Associated Syndromes

The protein associated with rye allergy is linked to Exercise Induced Anaphylaxis, more specifically wheat dependent exercise induced anaphylaxis.

Coeliac disease is not an allergic condition, but is triggered by gluten found in rye to which sensitive individuals may react.

Cross Reactivity

If you react to wheat, especially with anaphylaxis symptoms after exercising then you may want to also avoid consumption of rye.

Rye is in the Poales order of plants, so there may be some cross reactivity with other foods in the group such as wheat, barley and maize.

Wheat also contains dimeric alpha-amylase/trypsin inhibitor, so there may be some cross reactivity if you have airway reactions to rye.

None of these food lists are completely exhaustive, the most up to date food lists are on the Cross Reactivity Tool.
