If we keep in mind that milk fat
globules are the natural vehicles secreted by female mammals to
deliver lipids to their infant, it is possible that, among the wide size
distribution of fat globules, small and large milk fat globules may
play different and specific roles in the gastrointestinal tract of
the infants. The specific compositions and structures, revealed
according to the size of milk fat globules, need to be further studied
in regard to their potential physiological, nutritional and health
consequences. Such understanding of milk fat globules properties,
as a function of their size, could lead to the development of foods
with improved health-properties, adapted for populations such
as infants or elderly persons.
