Hazel Pollen – Allergy Resources

There are 3 airway allergens associated with hazel tree pollen, Cor a 1, Cor a 6 and Cor a 10. There are 8 allergens associated with eating hazelnuts, you can find more information on the Hazelnut page.

Cor a 1 is a Bet v 1 allergen, which means people suffering from this particular allergen will also be allergic to the pollen from birch trees.

Cor a 6 is an isoflavone reductase protein and Cor a 10 is a luminal binding protein.

Hazel pollen occurs in the UK between January and April, peaking in February. This varies in different countries. It is considered to have medium to high allergenicity.

I have put together some more comprehensive resources at http://www.allergyresources.co.uk/Hazel.php

The allergy resources page for hazel pollen covers the key allergens, which allergic syndromes are linked to this allergy and other foods which are commonly cross reactive with hazel pollen.

There is also regularly updated links to useful websites specifically for hazel pollen allergies and the latest research papers on the topic.

If you have multiple allergies and are interested in how they are linked or want to find out more about food allergies outside the usual top 14 then you can follow me on Facebook or Twitter, where I share a food allergy card every day of the week.
