TLDR
One sample of milk is sufficient to give a reliable estimate of the zinc concentration in milk, and two samples taken on consecutive days are required for a reliable estimates of iron and copper concentrations.Abstract:
Objective: To assess the within-subject and between-subject coefficients of variation (CV) of iron, zinc and copper concentrations in the milk of Guatemalan mothers. Methods: We performed a cross-sectional study in lactating women who had delivered a healthy infant 1 to 6 months previously in two low-income peri-urban areas (San Bartolome ´ Milpas Altas and Ciudad Peronia) and a low-income rural area (San Juan Chamelco) in Guatemala. Women infested with Ascaris lumbricoides or Trichuris trichiura received a single dose of albendazole (400 mg) or placebo. Two weeks after treatment, milk samples were collected on 3 or 4 consecutive days. Trace element concentrations in milk were measured by inductively coupled plasma/atomic emission spectrometry. Results: The instrumental error of the inductively coupled plasma/atomic emission spectrometry method, expressed as SD, was 0.04, 0.27 and 0.02 mg/L for iron, zinc and copper, respectively. Concentrations in milk samples collected from 47 mothers on 3 or 4 consecutive days, expressed as mean 6 SD, were 0.28 6 0.13, 2.03 6 0.37 and 0.29 6 0.07 mg/L for iron, zinc and copper, respectively. The within-subject CV was 46.1%, 18.2%, and 22.8% and the between-subject CV was 61.2%, 48.3% and 31.7% for iron, zinc and copper, respectively. Stage of lactation, infestation with intestinal parasites and residential area had a significant influence on milk zinc, copper and iron concentrations. Conclusions: One sample of milk is sufficient to give a reliable estimate of the zinc concentration in milk. Two samples taken on consecutive days are required for a reliable estimate of iron and copper concentrations. JPGN 40:128–134, 2005.read more

Cadmium, Lead, Copper and Zinc in Breast Milk in Poland
TL;DR: Assessing the content of Cd, Pb, Cu and Zn in human breast milk, as well as estimating the mean weekly intake of these metals by breast-fed infants from Poland, found that the admissible levels of supply of these toxic metals has not been exceeded, but their contents were high, particularly in 6-month-old infants.

Dietary intervention strategies to enhance zinc nutrition: promotion and support of breastfeeding for infants and young children
TL;DR: Estimates of the amount of zinc transferred in breastmilk to children of different ages and public health programs to promote and support breastfeeding should be included among the strategies to ensure adequate zinc status of young children.

Minerals and Trace Elements in Human Breast Milk Are Associated with Guatemalan Infant Anthropometric Outcomes within the First 6 Months
TL;DR: Estimated breast-milk intakes during established lactation were insufficient to compensate for the lower milk sodium, copper, manganese, and zinc concentrations in male infants and the lower sodium, iron and manginese concentrations in female infants.

Calcium, Magnesium, Iron, Zinc and Copper, Compositions of Human Milk from Populations with Cereal and ‘Enset’ Based Diets
TL;DR: Milk samples from Jimma were found to have significantly higher levels of Ca and Cu than those of rural Welkite, and breast milk Ca andCu levels were thus found to be influenced by dietary intake.

Association of Maternal Diet With Zinc, Copper, and Iron Concentrations in Transitional Human Milk Produced by Korean Mothers
TL;DR: In this article, the authors evaluated zinc, copper, and iron concentrations in the transitory milk of Korean lactating mothers and investigated the relationship between these concentrations and maternal diet, concluding that associations between maternal diet and nutrient concentrations in transitory human milk can provide useful information, particularly in regard to infant growth.

Number of days of food intake records required to estimate individual and group nutrient intakes with defined confidence.
TL;DR: The results indicated that the number of days of food intake records needed to predict the usual nutrient intake of an individual varied substantially among individuals for the same nutrient and within individuals for different nutrients.

Copper Deficiency in Humans
TL;DR: The features seen in Menkes' syndrome suggest that human beings may be rather susceptible to the vascular and neurological effects of copper deficiency; these effects may be encountered as a consequence of prolonged mild copper deficiency.

Existence of consistent hypo- and hyperresponders to dietary cholesterol in man
TL;DR: It is concluded that modest differences in responsiveness of serum cholesterol to dietary cholesterol do exist in man, and that the wide scatter of responses observed in single experiments is largely due to chance fluctuations.
