Infancy has been proven as the best time to improve health outcomes for the later stage of life. The composition of human breast milk has evolved over millennia to support and maintain the infant's life during the early years of life. To achieve life-sustaining effects, human breast milk is packed with fats, proteins, carbohydrates, and a wide range of bioactive compounds such as immunoglobulins, lactoferrin, and cytokines. The immunological compounds in breast milk have been shown to curtail gastrointestinal tract infections, respiratory tract infections, hospital admissions, acute otitis media, allergic reactions, and urinary tract infections. Although breastfeeding causes newborns to gain less weight at the beginning of their lives than formula milk does, breast milk improves body composition by low adiposity. A higher adipose deposition in infants is linked with an increased risk of child obesity in the future. Due to significant health benefits, the World Health Organization (WHO) recommends initiating breastfeeding within one hour after birth and continuing for at least six months. Breastfeeding has emerged as a superior source of nutrition that can promote healthy physiological and cognitive development and protect against disease challenges in low birthweight infants. This review summarizes potential evidence that highlights the potential health impact of breast milk in low birthweight infants.
