This study was conducted to compare the lipid content and fatty acid composition of the Korean breast milk produced at 1, 2 and 3 months postpartum with the infant formula produced Korea. The content of total lipids of the breast milk was low
compared
with the other data of Korean as well as foreign breast milk and the content tended to reduce during the progress of lactation. The composition of fatty acids of the breast milk was characterized by low saturated fatty acids(SFA) and high ω3
series of
polyunsaturated fatty acids (PUFA) especially 20 : 5 and 22 : 6, so the P/S and ω6/ω3 ratios were high. The formulas had more total lipids, triglycerides(TG) and phospholipids and less cholesterol(CHOL) and free fatty acids than the breast
milk.
The
cholesterol content of the formulas was around 50% of that of the breast milk, so the DHOL/TG ratio was low. Although the formulas varied in fatty acid composition, the formulas had more SFA and ω6 series of PUFA, but less monounsaturated aftty
acids
and ω3 series of PUFA than the breast milk. This study shows that there are some differences in lipid content and fatty acid composition between breast milk and infant formula. Therefore, further studies needed to investigate the physiological
effect
of this difference on lipid metabolism of infants.
