Abstract
Breastfeeding is a critical component in shaping the immunological foundation of infants, influencing not only immediate protection against infections but also long-term health outcomes. Human breast milk contains a rich array of immunologically active components such as secretory immunoglobulin a (sIgA), lactoferrin, oligosaccharides, cytokines, immune cells, and beneficial microbiota that work synergistically to protect the infant from pathogens. Moreover, breastfeeding fosters the development of the infant gut microbiome, supports mucosal immunity, and enhances the maturation of the immune system. Emphasis is placed on the biological, clinical, and epidemiological evidence that positions breastfeeding as a natural and powerful tool in strengthening infant immunity. Breastfeeding plays an indispensable role in shaping an infant’s immune system and laying the foundation for lifelong health. Human breast milk is not merely a source of nutrition it is a dynamic, bioactive substance rich in immunological components including immunoglobulins (especially IgA), cytokines, lactoferrin, oligosaccharides, leukocytes, and beneficial microbiota. These components help protect the neonate against infections, reduce inflammation, and modulate the development of the gut and immune system. Beyond the immediate protective effects against respiratory, gastrointestinal, and systemic infections, breastfeeding also imparts long-term benefits such as reduced risk of allergies, asthma, obesity, diabetes, and even certain autoimmune and cardiovascular diseases. The duration and exclusivity of breastfeeding are critical factors influencing the strength and longevity of these benefits. In the context of global health, promoting and supporting breastfeeding is a cost-effective strategy to improve child survival, health equity, and resistance to emerging diseases.
