Peanut Allergy

What is Peanut Allergy?

Peanut allergy is one of the most common food allergies in children. It happens when the immune system mistakenly sees proteins in peanuts as harmful, leading to an allergic reaction.

About 2% of children in the UK have a peanut allergy, and this number is increasing. Children who have eczema from a young age are also at a higher risk of developing peanut allergy with this being around 1 in 5.

Most children develop a peanut allergy in early childhood, though it can sometimes start later.

What is a peanut?

Peanuts are legumes and not related to tree nuts like Brazil, almonds, walnuts or cashews, so a peanut allergy doesn’t automatically mean your child will be allergic to these nuts, also called tree nuts. 

However, about 25-40% of children with a peanut allergy also have an allergy to at least one tree nut. Additionally, a peanut allergy increases the chance of being allergic to sesame and lupin.
