“…Thus, a wide deviation in milk iron concentrations is possibly due to iron supplementation. Several studies have also mentioned that these differences may be explained by geographical and nutritional influences [ 22 23 24 ], as well as differences in sampling procedures [ 25 ].…”

The aims of this study were to evaluate zinc, copper, and iron concentrations in the transitory milk of Korean lactating mothers and to investigate the relationship between these concentrations and maternal diet. Human milk samples were collected between 5 and 15 days postpartum from 96 healthy, lactating mothers in postpartum care centers in Seoul, Korea. Dietary intake during lactation was determined based on a 3-day dietary record. The mean zinc, copper, and iron concentrations in the human milk samples collected were 3.88 ± 1.74 mg/L, 0.69 ± 0.25 mg/L, and 5.85 ± 8.53 mg/L, respectively. The mothers who consumed alcoholic beverages during pregnancy had tended to have lower concentrations of zinc and copper, as well as significantly lower concentrations of iron, in their milk (p < 0.047). In contrast, the mothers who took daily supplements had much higher iron concentrations in their milk (p = 0.002). Dietary intakes of zinc, copper, and iron during lactation did not affect the concentrations of zinc, copper, and iron in the milk samples analyzed. Intakes of vitamin C, selenium, and iodine were associated with the concentration of copper in the milk samples analyzed, and consumption of food categorized as 'meat and meat products' was positively associated with the concentration of zinc. Consumption of rice was the top contributor to the concentrations of all three minerals. In conclusion, associations between maternal diet and nutrient concentrations in transitory human milk can provide useful information, particularly in regard to infant growth.

“…The composition of minerals in breast milk is variable (Benemariya et al 1995), and it is known that the composition of human milk varies with the stage of lactation and even among mothers (Yoshinaga et al 1991). This study showed that the concentration of sodium, potassium and phosphorus increased in the milk of hypertensive mothers and varied by the phase of the day and stage of lactation.…”

The aim of this study was to evaluate the changes in minerals, antibodies, complement and cytokine levels in the human milk of hypertensive women based on the time of collection (diurnal/nocturnal) and the type of milk. The material was collected from 23 mothers at three stages of maturity: 3 days (colostrum), 10 days (transitional milk) and 30 days (mature milk) postpartum -and at two times -diurnal (12:00 h) and nocturnal (24:00 h) -resulting in a total of 138 samples. The minerals, antibody, complement, IFN-γ and TGF-β cytokine levels were determined. Increases in sodium and potassium were observed independent of phase, while phosphorus was observed only during nocturnal period. IgA was higher in the transitional milk of hypertensive mothers in the nocturnal period. IgG was higher in the nocturnal period of hypertensive mothers regardless of milk maturation. The C3 protein increased during the diurnal period in the transitional and mature milk of hypertensive women. Milk concentrations of the cytokines IFN-γ and TGF-β were higher during the nocturnal period of hypertensive mothers. These data suggest that the milk of hypertensive mothers exhibits alterations proteins and inflammatory mediators, and these alterations are dependent on time and milk maturation.

A ocorrência de produtos químicos no leite materno é assunto importante para a prática pediátrica, de saúde pública e para a saúde ambiental da população. Os metais têm grande facilidade de se difundir rapidamente e atravessar a placenta, ou seja, a criança pode estar exposta antes e após o nascimento. Portanto, são pertinentes mais revisões literárias e pesquisas sobre os metais pesados e suas implicações para a saúde ao ingerir um leite contendo esses elementos. Palavras-chave: cádmio; chumbo; leite materno.The occurrence of chemicals in breast milk is important issue for pediatric practice , public health and environmental health. The metals have great easiness to spread rapidly and cross the placenta , or the child can be exposed before and after birth. So they are relevant literature reviews and research on heavy metals and their implications for health by eating one milk containing these elements.
