Which is a major benefit of breastfeeding for infants?

Breastfeeding offers a multitude of benefits for infants, and one of the most significant is the reduced risk of infections. Breast milk contains antibodies and other immunological factors that help protect infants from various illnesses and infections. Unlike formula, which lacks these natural immunological properties, human milk provides essential elements like secretory immunoglobulin A (IgA), which coats the gut and prevents the entry of pathogens, as well as other components that promote healthy gut flora and enhance immune response. This protective effect is particularly crucial during the first few months of life when infants are developing their immune systems.

While increased weight gain, improved eyesight, and better social skills may have some association with breastfeeding, they do not encompass the critical immune protection that breastfeeding provides against infections, making this benefit particularly salient in the early stages of an infant’s development. Breastfeeding significantly contributes to overall health and survival by minimizing the risk of conditions such as diarrhea, respiratory infections, and other infectious diseases.
