Evidence gaps and research needs in current guidance on feeding children from birth to 24 months

A United States National Academies report summarized recommendations on what and how to feed infants and young children in high-income countries from 43 eligible guideline documents. Consistency existed across many recommendations, but some differences occurred in topic areas, age groupings, and methodological approaches. Future development of guidelines on feeding of infants and young children requires new research and a rigorous evidence-based review process that is harmonized within and across countries and incorporates dissemination and implementation guidance. Novelty: New research and rigorous methods are recommended to develop future harmonized guidance on feeding of infants and young children that incorporates dissemination and implementation methods.
