Food allergy prevention

The last few years have seen a substancial shift in our understanding of how to prevent food allergies. With the publication of the LEAP study ( and the EAT study (, we now know that, food allergies can be prevented by introducing solid foods into your child’s diet before 6 months of age, including introducing allergenic foods. This guidance is now available at the British Society for Allergy and Clinical Immunology (

Children with early onset eczema, requiring prescribed steroid creams for their eczema have a 50% chance of having peanut, egg or sesame seed allergy by the time they are one year old so it is very important to try to prevent this.

At Children’s Allergy Doctors we can test to see if your child is already allergic to a food or ‘sensitised’ (which is when the allergy test is positive but we are not yet sure if they are allergic) and we can advise you on which foods can be safely introduced at home and which foods need to be introduced under supervision in case of an allergic reaction.

We provide a supervised feed and food challenge service to be able to confirm whether your child is allergic to a food or not. Thereafter, we tailor a food introduction plan for your child with the aim to prevent the development of food allergy, based on the latest research.

Even if your child is already allergic to one food, there may still be time to prevent them from developing allergies to other foods. I am leading the Pronuts study which is evaluating the effect on introducing selective nuts into the diet in children already allergic to peanut, tree nuts or sesame seed.

We work closely with paediatric allergy dietitians to assist with recipes and advice for introducing these foods into the diet and provide written and verbal advice on how to perform this safely and incorporate this into your daily routine.


What parents say:

“After being let down by the NHS for almost a year, our situation became desperate for our little girl who was suffering in many ways and we just didn’t know what to do anymore. Trying to get help and support during a pandemic was so difficult so we resorted to going private for help.

We came across Dr Brough where her profile was so inviting and experience so vast, we messaged her that night requesting an appointment. I couldn’t believe we had a reply the same evening, really late, offering us an appointment within days! Dr Brough is thorough, understanding, makes you felt heard and helps you as a worried parent to understand what is going on. We have found out so much from the tests she carried out, results the same day or within a few. A service we cannot fault.

Thanks to Dr Brough our little girl is no longer suffering! The improvement we have made within weeks is something we never imagined could happen. We cannot thank Dr Brough enough. Highly recommend”.
