Human breast milk serves as a complicated biological fluid that provides vital nutrients to support baby development, immune system defense, and brain growth. The formula includes macronutrients, which consist of lipids and lactose, and proteins, together with micronutrients and immunoglobulins, hormones, growth factors, antimicrobial peptides, and human milk oligosaccharides. Scientists began studying its components because people consume it outside its primary function of providing food to babies. This review presents human breast milk research that investigates its biochemical properties, its effects on human physiology, and its safety for adult consumption. The research team used PubMed, Scopus, and WHO databases to perform a narrative synthesis of peer-reviewed literature that spans the years 2000 to 2025. Research results show that human breast milk remains safe for adult use when it originates from healthy individuals who breastfeed.
The screening process for lactating individuals required them to maintain proper sanitary conditions. The research findings demonstrate that adults do not gain significant nutritional or immunological benefits because their bodies process most bioactive immune elements through the digestive system, which they cannot absorb into their bloodstream. Breast milk provides ideal nutritional value for infants who need to grow quickly because its composition does not meet the metabolic requirements of adult humans. The potential risks of infectious disease transmission through inadequate screening procedures, together with the dangers of storage and handling errors that lead to contamination, present an actual risk.
The process of obtaining informed consent, together with the need for cultural sensitivity, requires evaluation in all situations that do not involve infants. Human breast milk serves as a specialized biological fluid that provides optimal nutrition for infants, yet offers minimal value to adults who consume it for non-medical purposes.
