Mung beans (also known as green gram) are most commonly eaten in Asia, but they are becoming more popular worldwide.
Mung beans contain multiple allergenic proteins including a Bet v 1 protein, which can cause cross reactivity and a vicilin protein called Vig r 2. Vicilin proteins are commonly found in nuts and seeds.
Mung bean allergy has been associated with Pollen Food Allergy Syndrome due to the Bet v 1 like protein.
I have put together some more comprehensive resources at http://www.allergyresources.co.uk/Mung.php
The allergy resources page for mung beans covers the key allergens, which allergic syndromes are linked to this allergy and other foods which are commonly cross reactive with mung beans .
There is also regularly updated links to useful websites specifically for mung bean 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.
