It has been known since 1998 that around 20% of children with peanut allergy do outgrow their allergy.

Now researchers at Johns Hopkins Children's Center and Arkansas Children's Hospital have found that 9% of 278 children with tree-nut allergy also outgrew their allergies.

The children, some of whom had had anaphylactic reactions, had reacted to a variety of tree nuts including walnuts, almonds, Brazils, cashews and hazelnuts.

But it does seem that children who are allergic to more than one kind of nut are less likely to grow out of their allergies.

Children who are allergic to both peanuts and tree nuts, and who outgrow their peanut allergy, are also likely to outgrow their tree nut allergy. However, the researchers believe that if they are to grow out of their allergies they will have done so by the age of six.
