Abstract
The goal of this research was to explore the macronutrient composition in expressed stored human milk of mothers in East Texas. 5mL samples of human milk were warmed to 40oC, ultrasonically homogenized, and processed through a MIRIS Human Milk Analyzer for lipid, carbohydrate, protein, and energy levels. Macronutrient levels were analyzed via descriptive statistics and one-way ANOVA. The time of day of the milk expression was statistically significant for energy (p= 0.0001) and lipid (p= 0.0002) but not for carbohydrate or protein levels. The variation of lipid and energy was an unanticipated finding and is contrary to the current literature. The patterns of increased lipids at specific times have clinically important ramifications for the energy needs of premature infants. Further research is needed to characterize the causes of this fluctuation in lipid and energy content which may be related to maternal dietary intake.
