Copper, Selenium, and Zinc Concentrations in Human Milk During the First Three Weeks of Lactation

Abstract: Human milk samples were analyzed by neutron activation analysis (NAA) for three essential trace elements (Cu, Se, and Zn). Mothers' milk samples were collected from 25 lactating mothers from the Central Hospital, Tripoli, Libya. The average concentration level of Cu, Se, and Zn declined from 0.84 +/- 0.06 mg/L, 104 +/- 9.46 microg/L, and 16.1 +/- 2.67 mg/L at d 0 to 0.39 +/- 0.045 mg/L, 41.8 +/- 6.66 microg/L, and 4.95 +/- 1.3 mg/L, respectively, at d 20 of lactation. Copper and Zn levels in the Libyan mothers… Show more

“…The highest content of Zn was recorded in the breast milk of women from Libya and the lowest in women from Venezuela [39]. According to Hannan et al [39], the daily intake of Cu and Zn from the Libyan mothers' milk is higher than the recommended daily amount (RDA) value, whereas this study shows that the daily supply of Cu and Zn did not fully satisfy the infant's demand for those elements as defined by the Polish standard [33] and the WHO standard [40]. A low level of Cu causes no proven risk of nutritional deficiencies of Cu in the child during the first 6 months of lactation.…”

“…Human milk provides an adequate intake of macronutrients (proteins, lipids, carbohydrates) and micronutrients (minerals, vitamins, enzymes), changing their composition along lactating period from colostrum to mature milk [2,3] and can be used as a nutritional reference to develop infant formulas with a composition similar to that of maternal milk.…”
