3.1. Socio-demographic characteristics of milk sample donors
In this study, a total of 180 breast milk samples were analyzed in this study. The demographic characteristics of the groups according to dietary patterns are shown in Table 1. According to the energy supply ratio of the three major nutrients of the mother, 180 cases of mature milk were divided into three groups (fat group, carbohydrate group, and protein group), with 60 samples in each group. The average ages of mothers in three group were all approximately 30, and the pregnancy periods were approximately 39 weeks. The rate of natural delivery was slightly higher than that of cesarean section. All infants were full-term infants with birth weight of approximately 3.5 kg. Male infants were more than female infants. It can be seen from the table that there is no significant difference between mothers and newborns in each group. There was no significant difference in total energy intake among the three groups of mothers.
