The Effects of Protein on Infant Growth and Nutritional Health

Protein is a critical nutrient for infant growth and development and plays an essential role in maintaining their nutritional health. With the advancement of nutritional science and increased attention to infant well-being, the types and quality of protein have garnered widespread interest. This paper primarily introduces the sources and composition of protein intake in infants. Drawing upon existing literature, it reviews the relationship between protein and various aspects of infant development, including physical growth, micronutrient metabolism, immunity, gastrointestinal health, and sleep function. The aim is to provide a theoretical foundation for scientific infant feeding, and to present insights into the functions of protein and feeding strategies. The findings offer valuable guidance and reference for promoting the healthy development of infants.
