“…Maternal age, BMI, iron supplementation, and smoking do not affect breast milk selenium concentrations (165,239,247,250). One study found an inverse correlation between maternal parity and breast milk selenium in late lactation (251), although a similar association was not found in other studies (239,250).…”

The WHO recommends exclusive breastfeeding for the first 6 mo of life to promote optimal infant health and development. Understanding the micro- and macronutrient concentrations of human milk and how each nutrient fluctuates with lactational stage, maternal factors, and supplementation is imperative for supporting good breastfeeding practices. Where maternal undernutrition compromises human milk quality, a thorough awareness of the effectiveness of interventions can direct efforts to achieve both maternal and infant nutrient sufficiency. This review of current knowledge covers trends in nutrient concentrations over the course of lactation and describes the influence of maternal intake, status, supplementation, and other factors on human milk concentrations of each nutrient.

“…With regard to reproductive experience, there were no significant differences in maternal serum Se (Kumpulainen et al 1985) or in breast-milk Se (Mandic et al 1995) due to parity status. Indeed, Arnaud et al (1993a ) found no significant correlation between milk Se with parity or maternal age (Grandjean et al 1995).…”

“…However, Funk et al (1990) found an inverse correlation between parity and milk Se only in late lactation. Although there is a significant correlation between Se status (toenail Se) and smoking (Virtanen et al 1996), there was no significant difference in milk Se between smoking and non-smoking mothers (Mandic et al 1995).…”

The objective of the present review is to discuss Se nutrition during breast-feeding, encompassing environmental and maternal constitutional factors affecting breast-milk-Se metabolism and secretion. A literature search of Medline and Webofscience was used to retrieve and select papers dealing with Se and breast milk. Although Se in natural foods occurs only in organic form, breast milk responds to organic and inorganic Se in supplements. Inorganic Se (selenite, selenate), which is largely used in maternal supplements, is not detectable in breast milk. The mammary-gland regulating mechanism controls the synthesis and secretion of seleno-compounds throughout lactation, with a high total Se level in colostrum that decreases as lactation progresses. Se appears in breast milk as a component of specific seleno-proteins and selenoamino-acids in milk proteins that are well tolerated by breast-fed infants even in high amounts. Se in breast milk occurs as glutathione peroxidase (4 -32 % total Se) . selenocystamine . selenocystine . selenomethionine. The wide range of breast-milk Se concentrations depends on Se consumed in natural foods, which reflects the Se content of the soils where they are grown. Se prophylaxis, either through soil Se fertilization or maternal supplements, is effective in raising breast-milk Se concentration. In spite of wide variation, the median Se concentration from studies worldwide are 26, 18, 15, and 17 mg/l in colostrum (0 -5 d), transitional milk (6 -21 d), mature milk (1 -3 months) and late lactation (.5 months) respectively. Se recommendations for infants are presently not achieved in 30 % of the reported breast-milk Se concentrations; nevertheless Se status is greater in breast-fed than in formula-fed infants.

“…3). Some researchers did not also find statistically significant correlation between dietary selenium and milk selenium values [13] but some investigators found selenium concentration in breast milk to be closely related to dietary selenium intake [32][33][34].…”

“…Mineral concentrations in human milk generally do not correlate well with maternal intake, with the exception of selenium and iodine [10]. Some investigators report a positive correlation between dietary intake of selenium and iodine and the concentration of these trace elements in maternal milk [11,12], while others have been unable to demonstrate such a relationship [13]. Since there is no nutritional data available about the dietary intake of trace elements and their relationships to maternal milk composition of lactating mothers in Rio Grande Valley, this study was conducted to find relationships between estimated dietary intake of zinc, iron, selenium, and iodine and concentration of these elements in the maternal milk of lactating mothers.…”

The dietary intake of zinc (Zn), iron (Fe), selenium (Se), and iodine (I) of 31 lactating Mexican-American women attending the Hidalgo County WIC program in Rio Grande Valley (RGV), Texas was estimated from 24-h dietary recall interviews. Milk samples were obtained from lactating mothers who had infants 3 months of age and younger. Milk samples were collected in two visits to assess change in breast milk composition after 1-3 months postpartum: group A--after 30-45 days and group B--75-90 days. Dietary intakes indicated that the study participants had significantly inadequate percent energy intakes than the DRI (Dietary Recommended Intakes) percent recommended kilocalorie values but protein intakes were substantially higher than the percent recommended values. The estimated percent Zn, Fe, Se, and I intakes were also significantly lower than the DRI percent recommended values. The lactating mothers consumed significantly less Zn, Se, and I when compared to the Recommended Dietary Allowances (RDA) even though Fe intake was higher than the RDA value. Breast milk concentration of Zn, Fe, and Se were in agreement within the range of representative values for Constituents of Human Milk but I has significantly less concentration than the representative value. There was no statistically significant correlation observed between dietary intake and milk concentration of Zn, Fe, Se, and I. This study compares the estimated dietary intake of zinc, iron, selenium, and iodine to the concentration of these trace elements in the maternal milk of lactating women of Mexican-American heritage who attend the Rio Grande Valley WIC clinic.
