Essential Long-chain Polyunsaturated Fatty Acids Quantitation in Breast Milk Samples at Different Gestational Ages

Mother's milk is the best food for the newborn as it is the only one capable of providing species-specific nutrition, guaranteeing everything necessary for the growth and maturation of a child. Mother's milk has the property of satisfying metabolic needs by changes in the composition of nutrients, which are different at each stage of life. Various studies have shown that the milk of a preterm infant differs from that of a term infant in the composition of micronutrients, such as vitamins, macronutrients, carbohydrates and proteins. The metabolomic study of human milk would offer the advantage of offering the best type of nutrition for the newborn at each specific period of life, in the event of a lack of mother's milk. This is particularly important in a Neonatal Intensive Care Unit, where it is essential to ensure timely adequate enteral nutrition. This is possible if a bank of donated human milk is available. The study of lipidomics is of particular interest, as the role of fatty acids is known both as essential constituents of cell membranes and as molecules actively involved in energy metabolism. Therefore, the benefit deriving from an adequate dietary intake in a constantly evolving organism such as that of a newborn is extremely important.
