Olive Pollen – Allergy Resources

There are 15 pollen allergens associated with olive pollen, they are all allergens associated with airways.

Ole e 1 is a glycoprotein, it has high cross-reactivity with the main allergens of other plants in the Oleaceae family. Ole e 1 is the marker allergen for diagnosing these linked allergens and they are often called “Ole e 1-like”. Most patients with olive pollen allergy are linked to this allergen. Ole e 2 is a profilin protein, these are panallergens and can cause allergies across multiple species of plants and foods.

Ole e 7 is a lipid transfer protein, which can cause serious allergic reactions across multiple plants.

Ole e 3 and 8 are polcalcin proteins, these are calcium binding protein commonly associated with pollen germination. These proteins are highly cross reactive and also considered to be panallergens.

Olive pollen is more common in warmer European climates. Pollen season is between April and June. This varies from country to country. It is considered to have medium to high allergenicity.

Sensitisation to olive pollen does not mean you should avoid eating olives or using olive oil, there is very little evidence that there is cross reactivity through food.

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

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

There is also regularly updated links to useful websites specifically for olive 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.
