Sumario:Breast milk is a complex and multifaceted fluid that plays a critical role in the development of infants. It is composed of water, carbohydrates, fats, proteins, vitamins, and minerals, as well as numerous bioactive compounds such as hormones, oligosaccharides, and immune proteins. Additionally, breast milk contains microRNAs, which have been found to regulate gene expression and impact various aspects of infant development. This text provides an overview of the components of human breast milk and their importance in infant development, with a focus on microRNAs. MicroRNAs are short RNA sequences that regulate gene expression posttranscriptionally, and they play an important role in shaping the mechanisms of immunity, protecting against oxidative stress, and promoting thermogenesis. The composition of breast milk can vary in the same mother between different feedings, as it changes in response to various factors such as the infant's age, feeding frequency and duration, time of day, and maternal health status. Despite the variations in breast milk composition, it still provides complete nutrition for the infant. The unique microRNA profiles in breast milk and how they are affected by various factors can have significant implications for disease prevention and treatment. Further research is needed to better understand the functions of individual microRNA molecules and their potential therapeutic applications.
