Exposure by early consumption – regularly eating the food allergen

can protect


Immunotherapy with foodSupervised consumption of the food allergen

Start well broken down by cookingEg Milk in biscuit

Then increasingly intactEg Fromage frais

• Doesn’t work for all• Side effects • Life-long consumption?

Avoiding food allergensKnowing what EXACTLY to avoid

Knowing where it is used

Reading labels

Talking to staff

Looking up online

Being ready to manage symptoms


Labelling – changing behaviourMore food is sold online and through third party businesses
