In this study relationships between patterns of Se and lipid secretion in milk of women on self-selected diets were assessed. Milk samples were collected from 10 women at 4, 6 and 8 wks postpartum and blood samples at 4 to 8 wks. Milk samples were extracted and analyzed for tiacylglycerols and fatty acids. Activity of glutathione peroxidase (GSH-Px) and contents of Se in milk, plasma and erythrocytes were also measured. Two groups were found: one displaying an increase in plasma Se and the other, a decrease from 4 to 8 wks. Milk Se significantly decreased only in women whose plasma Se also decreased. Milk Se was negatively correlated with myristic and stearic acids in women whose plasma Se increased and with arachidonic, eicosapentaenoic and docosahexaenoic acids in women whose plasma Se decreased. Results of this study show that maternal Se nutrition relates not only to the quantity of Se secreted in milk but also to the quantities of individual fatty acids.
