Helping to prevent the development of food allergy in infants
Recommendations for the introduction of common allergens to infants have changed as research has emerged on ways to help prevent the development of food allergy in babies.
A 2021 position statement co-published by the Canadian Paediatric Society (CPS) and the Canadian Society of Allergy and Clinical Immunology (CSACI) includes recommendations on the specific timing of early introduction of allergenic foods for high-risk infants. In 2023, the CSACI reinforced the importance of regular ingestion as a means of food allergy prevention. A 2025 study has found that food allergy rates have declined since families began following early introduction practices.
The current guidance is to feed a baby the foods that most commonly cause food allergy at around 6 months of age and continue to feed them to a baby. If a baby is high risk for developing food allergy, introduction can start earlier than 6 months when developmentally ready, but not before 4 months.
The release of the position statement followed the CPS’ 2019 practice point which first outlined this specific timing.
