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.

The current guidance is to actively offer non-choking forms of foods containing common allergens (e.g., peanut, egg) around 6 months of age, but not before 4 months, as this can be effective in preventing food allergy in some high-risk infants. This specific timing and ongoing feeding of the food(s) is reinforced, along with other recommendations, in the position statement.

The release of the position statement followed the CPS’ 2019 practice point which first outlined this specific timing.

Infants who are not considered high risk should start to receive complementary foods when they are around 6 months of age and show signs of developmental readiness.
