Challenges implementing recent recommendations of daily formula supplementation for allergy prevention and practical real-world options.

The Canadian Paediatric Society's Position statement 'Dietary exposures and allergy prevention in high-risk infants' December 2021 provides recommendations for regular ingestion of cow's milk protein (CMP) once introduced in early infancy. These recommendations are based on evidence from randomized controlled trials (RCTs) where researchers supported participants in adhering to diet recommendations. Real-life dilemmas that relate to dietary adherence including cost, food wastage, and practicality are not addressed and are the crux of where -evidence-based recommendations fail. This commentary highlights the difficulties in carrying out the proposed recommendation for regular ingestion of CMP in practice and offers three practical real-world options instead.
