Up to 40% of children with moderate to severe
atopic dermatitis also have some type of
food allergy.1 Although the
link between food allergies and atopic dermatitis is not fully understood, some
children with atopic dermatitis are thought to have a food allergy that
triggers rash and itching.
A few common foods are responsible for most allergic
reactions.2 In adults, shellfish, fish, tree nuts
(such as walnuts or almonds), and peanuts cause 90% of the allergic reactions.
In children, foods high in protein cause 90% of the allergic reactions. These
include peanuts, milk, wheat, soy, tree nuts, and eggs.
With the help of a health professional, you can
determine whether certain foods are linked to your or your child's symptoms by
trying an elimination diet. However, there is little evidence that
dietary restrictions improve symptoms of atopic dermatitis.
An elimination diet consists of the following
steps:
- Eliminate one food from the diet at a time,
observing and recording any changes in symptoms over the next days or weeks.
- Reintroduce the suspected food to the diet. Foods that
you are allergic to will cause an
allergic reaction within a few hours.
But foods will not make atopic dermatitis symptoms show up within
hours.
