title: Association between lutein intake and lutein concentrations in human milk samples from lactating mothers in South Korea.
abstract: This study was performed to investigate the association between maternal lutein intake and lutein concentrations in human milk among exclusive breast-feeding and mixed-feeding groups of lactating mothers in South Korea. From 99 women who were recruited from March to July 2015, dietary data and breast milk samples were obtained. The means of the daily lutein intakes and breast milk lutein concentrations in lactating mothers were 4.04 mg/day and 10.06 μg/dl, respectively, and they did not differ according to the type of breast-feeding. Breast milk lutein concentrations were positively correlated with the dietary lutein intake of lactating mothers after adjustment for the infant's age and supplement use by the lactating women (r=0.3337, P=0.0008). These correlations appeared in both groups. Further research is needed to identify whether breast milk lutein levels influence infant health, especially eye health.European Journal of Clinical Nutrition advance online publication, 25 May 2016; doi:10.1038/ejcn.2016.84.
