The lupin is a popular flower with tall, colourful spikes. Some species of lupin are also grown for their seeds which can be used in foods. The seeds are normally crushed to make lupin flour which can be used as an ingredient when making pasta, pancakes, and baked goods such as pastries and pies. Lupin is not commonly used as an ingredient in products produced in the UK but is used more commonly in mainland Europe. This means that Lupin allergy is more common in other parts of Europe where it is used in foods more often.
Lupin is a type of legume, which is the same plant family that peanuts belong to. This means some people with peanut allergy may also be allergic to lupin as they contain similar proteins. However, you do not need to automatically avoid lupin if you are allergic to peanuts as only a small number of people with peanut allergy will also be allergic to lupin.
