This was previously called Oral Allergy Syndrome (OAS), the term was coined to define the symptoms. It has now been termed Pollen Food Allergy Syndrome (PFAS) more definitively as it mostly affects people who already suffer from pollen allergies and seasonal rhinitis due to cross reactivity.
I have put together some more comprehensive resources at http://www.allergyresources.co.uk/PFAS.php
The allergy resources page for pollen food allergy syndrome covers the key allergens and foods which are commonly cross reactive.
There is also regularly updated links to useful websites specifically for pollen food allergy syndrome 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.
