Human milk metabolome: Impact of gestational age, lactational stage and maternal diet.

Abstract

Human breast milk due to its unique composition and the ability to adapt to the needs of the infant, is referred to as the "gold standard". Exclusive breastfeeding is recommended for the first 6 months of a inflant's life. The composition of breast milk and its metabolites is not constant and varies depending on the influence of various factors. Its analysis allows for rational management of infant nutrition. Intermediate and final metabolites of human milk are formed as a result of various metabolic processes in the mammary gland, and their role and the influence of various factors on them are not fully determined in the context of the proper development of infants. Metabolomic studies can be used to identify intermediate and terminal metabolites in breast milk. The aim of the study was to review the current literature on the variability of human milk metabolome depending on factors such as gestational age, lactation stage and mother's diet. A review of current research shows that the composition of human milk metabolome varies depending on various factors. Better understanding of metabolome of breast milk could be crucial in the future programming of metabolic processes in infants, which is crucial in preventing many diseases and maintaining health.
