“…Trace elements are probably secreted inde pendently of each other and the higher con centration of zinc in milk than in maternal serum suggests and active transport [39]. Cop per and selenium concentrations in human milk reported here are in agreement with those reported by others in developed [34,[37][38][39][40]45] or developing countries [38,44,45]. How ever, as noted in maternal serum (see above), selenium concentration in the breast milk from Nigérien women was higher than that in the breast milk from women living in coun tries with low selenium soils [27,36].…”

“…Copper, iron and selenium concentrations in breast milk are lower than in maternal serum, whereas zinc concentration is higher. With the exception of selenium, trace element levels in breast milk do not seem to be correlated with mother sta tus [15,28,33,39,40]. The secretion of trace elements in milk is incompletely understood.…”

“…The decline in trace element concentra tions in breast milk throughout lactation is well known [27,[32][33][34][39][40][41][42][43], This decline appears to be physiological and might be ex plained by changes in binding proteins. How ever, variations from study to study are wide, due to sample contamination, and analytical and geographic variations.…”

Trace element concentrations in serum and breast milk were studied longitudinally in 197 Nigerien women from 6 months of gestation to 6 months postpartum; 99 of them received a daily iron supplement of 100 mg from 6 months of gestation to delivery. During the last 3 months of pregnancy, serum selenium declined, whereas serum zinc remained unchanged and serum copper increased. After delivery, copper concentration in maternal serum decreased, whereas serum zinc increased from delivery to 3 months postpartum and then reached a plateau. Serum selenium increased from delivery to 6 months postpartum. In breast milk, selenium and zinc decreased from 5 days to 6 months postpartum. Copper in breast milk also declined during the course of lactation but reached a plateau by 3 months postpartum. Iron concentration in breast milk remained unchanged during the study. Iron supplementation had no significant effect upon the concentrations of copper, selenium and zinc in mother serum and breast milk. In umbilical serum, iron status, copper and zinc levels were similar in the two groups, whereas, unexpectedly, selenium concentration was significantly decreased (p < 0.03) in the iron-supplemented group. Taken together, our results suggest that the benefical effect of iron supplementation on iron deficiency was not associated with an adverse effect on copper and zinc status. On the other hand, our results suggest that Nigerien women had a marginal zinc status but an adequate selenium status.

“…The values continued to decrease until around 3 months of lactation, and main tained a constant level thereafter (Fig. 5 the world (30,(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50). Concentrations of zinc and copper in colostrum were high and rapidly decreased in the first 2 to 3 weeks after parturition and then stabilized in the later days of lactation.…”

“…The additional EAR for pregnant women, which was determined by measurement of zinc storage during pregnancy (0.40 mg/d) (28) and extent of zinc absorption (27%) (19), was set at 1 mg/d. The additional EAR for lactating women, which was determined by measurement of average zinc content in Japanese breast milk (1.83 mg/L) (29,30), average intake of breast milk in Japanese infants (0.78 L/d) (11, …”
