Abstract
|
|
|
This study was conducted longitudinally following the total lipid and cholesterol content, fatty acids composition and Vitamin E content in human milk from 2-5 days to 12 weeks postpartum of 45 lactating Korean mothers. All samples were from well-defined subjects and uniform collection procedures were used. Total lipid concentration increased from 1.98g/dl at 2-5 days to 3.09g/dl at 12 weeks postpartum. However, there was a large variation in the concentration of total lipids. Total cholesterol concentration tended to decrease from 20.68mg/dl at 2-5days to 17.19mg/dl at 12 weeks. In comparison with transitional and mature milk, human colostrum was characterized by a lower percentage of saturated fatty acids including medium chain length fatty acids and a higher percentage of monounsatureated fatty acids and polyunsaturated fatty acids. Therefore, the P/S and M/S ratios of human milk lipids decreased significanlty during lactation. P/M/S ratio of colostrum changed from 0.38 : 0.84 : 1.00 at 2-5 days to 0.29 : 0.61 : 1.00 at 12 weeks of mature milk. Total tocopherol concentration decreased significantly from 833 ug/dl at 2-5 days to 300 ug/dl at 12 weeks.
