There are lots of different species of lupin, but it is best known as a common garden plant

The seeds for lupin can be eaten whole or used for flour. Lupin flour is widely used in some parts of Europe
A study in France by Gayraud et al (2009) showed 17% of children with a peanut allergy also had a reaction to lupin, and 15% of adults. They suggest that for anyone that has a peanut allergy, a prick-test to lupin is also valuable
Studies have found that if you are allergic to peanuts, there is a chance that you will also react to lupin which is called cross-sensitivity (Anaphylaxis Campaign 2016)
Some companies use lupin as an alternative to soya flour
The Anaphylaxis Campaign (2016) recommend seeing your GP as soon as possible if you think you may have a lupin allergy. It is likely they will then refer on to an Allergy Clinic
