Abstract

Lipid is the major energy source for the breastfeeding newborn. It is well known that a number of factors influence the lipid composition of human milk.1 These include lactational period, maternal diet, duration of a feed, time of collection, feeding interval, gestational age, parity, maternal age and adiposity. In general, although boys are born bigger than girls and their growth curve maintain the difference, no report seems to indicate a relationship between breast milk lipid composition and the gender of the baby. In a single feed, the lipid content of the milk increases from fore to hindmilk, and, for our knowledge, sexual differences have not been documented.
