Abstract |
: |
Information on the secretion of trace elements in human milk
is needed, not only in order to estimate the intake by the breast-fed
infant, but also as a starting point for recommendations of intakes from
other types of infant foods and minerals diets during lactation.
Duration of lactation, particularly in the first few weeks, markedly
affects concentrations of some elements, including iron, zinc and
manganese. Zinc, copper, iron, chromium, cadmium, manganese and
lead were measured in breast milk samples collected from 11 healthy
lactating mothers. Samples were collected from day of delivery to 15
days postpartum. The mean (±SD) concentration values in ppb of Zn,
Cu, Fe, Mn, Cr, Cd and Pb in the morning samples are 2330.8±3.1,
491.9±1.8, 164.3±1.4, 18.2±0.3, 7.1±0.3, 2.03±0.01 and 1.47±0.01
respectively while those in the afternoon samples are 2434.6±2.9,
562.1±2.1, 299.9±2.0, 24.5±0.5, 20.2±0.7, 4.6±0.1 and 1.76±0.1
respectively. The concentrations of the elements in milk samples
collected in the afternoon are higher than those in the morning samples.
There is an apparent decline in the mean concentration levels as the
stage of lactation progressed. Our results are also compared with the
corresponding values of different countries available in literature. It is
observed that the concentration levels of the elements studied in breast
milk of Saudi mothers are well comparable with the values reported
elsewhere in the world. |
