The main ingredient in breast milk that supports brain development is human milk oligosaccharides (HMOs). These complex carbohydrates play a crucial role in the growth and development of an infant's brain by promoting the growth of beneficial gut bacteria and enhancing immune function. The presence of HMOs contributes to cognitive development as they can influence the maturation of the brain and nervous system.

While proteins, fatty acids, and vitamins are also important components of breast milk that contribute to overall growth and health, HMOs are specifically highlighted for their unique role in neurodevelopment. Fatty acids, particularly long-chain polyunsaturated fatty acids (such as DHA), are important for brain development as well. However, HMOs offer benefits that extend beyond nutrition by supporting the gut microbiome, which indirectly affects cognitive and immune health. Therefore, human milk oligosaccharides stand out as a key ingredient in promoting brain development in infants.
