Childhood Food Allergy: Outgrowing, Challenging and Long-Term Tolerance

In this episode we’re joined by Professor Adam Fox OBE, and Professor Rosan Meyer. Professor Fox is a leading Consultant Paediatric Allergist at Evelina London Children’s Hospital, Professor of Paediatric Allergy at King’s College London, and co-founder of London’s first specialist allergy hospital, the Allergy Centre of Excellence. Professor Meyer is a leading Specialist Paediatric Dietitian, Senior Lecturer in Paediatrics at Imperial College London, Professor at KU Leuven and Winchester University, and founder of SBS Kidz Nutrition.Together Prof. Fox and Prof. Meyer answer the questions families and clinicians frequently ask about outgrowing food allergies. We explore what “outgrowing” really means, how likely children are to become tolerant to different foods and how age and clinical history affect those odds. We walk through the clinical pathway — referrals, testing, follow-up frequency — and explain the specialist dietitian’s role in assessment and management. We also cover the risk of recurrence and the red flags that should prompt urgent review.Prof. Meyer also offers realistic, low-cost tips for keeping foods in the diet, handling ‘may contain’ labels, managing dislikes and preventing cross-contact at home.Whether you’re a parent, carer or healthcare professional, this episode gives clear, evidence-based guidance and practical steps to help families navigate childhood allergies.
