Complementary feeding in Mexico by 2026: a review and recommendations from the Academia Mexicana de Pediatría

The present document aims to present a reflection derived from a narrative review on the evolution of complementary feeding (CF) recommendations worldwide and their application in Mexico. Based on the analysis of international guidelines and consensus statements, such as those published by European Society for Pediatric Gastroenterology, Hepatology and Nutrition, Latin American Society of Pediatric Gastroenterology, Hepatology and Nutrition, and the World Health Organization, members of the Mexican Academy of Pediatrics review the main points of convergence and controversy related to the initiation, progression, and characteristics of CF during the first two years of life. The document highlights that this period is critical for growth, neurological development, immune maturation, and the establishment of healthy eating habits in the long term. Likewise, it emphasizes the relevance of the first 1000 days of life and the need to promote breastfeeding, dietary diversity, and the timely introduction of foods rich in essential nutrients. The review also addresses current topics such as the early introduction of allergenic foods, the role of different food textures, the prevention of obesity and allergies, as well as the importance of avoiding sugar-sweetened beverages, ultra-processed foods, and restrictive diets without specialized supervision. From the Mexican perspective, it is recognized that international recommendations must be contextualized according to the epidemiological, cultural, and social realities of the country. Finally, the Academia Mexicana de Pediatría proposes practical recommendations directed at healthcare professionals to promote responsive, safe, and evidence-based CF that contributes to the overall well-being of Mexican infants.
