The Importance of Gut Microbiota in Infant Health: Understanding the Impact of Feeding

The gut microbiota is a complex ecosystem that plays a significant role in human health, particularly during infancy. This review examines the effects of breastfeeding and formula feeding on the gut microbiota based on research conducted over the past five years.Various studies have shown that infants who are breastfed have a richer and more balanced microbiota profile. The natural prebiotics and probiotics found in breast milk support the growth of beneficial bacteria, particularly Bifidobacterium and Lactobacillus, helping to protect infants against infections. In contrast, infants who are formula-fed generally exhibit lower microbiota diversity and an increased presence of potentially harmful bacteria. This situation can negatively impact the development of the immune system and increase the risk of allergic diseases.The review also explores the impact of dietary habits from different geographical regions on the microbiota; recommendations for future research are provided, and the importance of promoting breastfeeding is emphasized. Breastfeeding plays a critical role not only in infant nutrition but also in strengthening the mother-infant bond and providing long-term health benefits. Therefore, raising awareness in the community about this issue is essential for helping infants achieve optimal health levels.
