Introduction
Human milk represents the optimal nutrition for a baby
after birth and during the whole nursing period. Progressive
discoveries of its particular components together with
determining their physiological functions has allowed
better understanding of this unique liquid. Besides nutritional
functions, we can distinguish a whole spectrum of
functions in human milk, including immunomodulatory
and other physiological activities. Revealing the function
and importance of particular components has allowed for
improvement of modern supplemental milk formulas for
infants who, for various reasons, cannot be breastfed.
Modern preparations of supplemental milk nutrition try
to copy and imitate the components of human milk to
achieve not only its nutritional properties, but also other
physiological functions that are provided by human milk
to a breastfed child [1].
