“…Following delivery, iodine concentration in human milk is approximately 200–400 µg/l in colostrum, but decreases during the next few weeks and remains steady in mature milk 6 . The uptake of iodine by the mammary gland during lactation may reduce the maternal iodine pool in case of inadequate iodine status 11 .…”

“…Following delivery, iodine concentration in human milk is approximately 200 -400 μ g/l in colostrum, but decreases during the next few weeks and remains steady in mature milk. 6 The uptake of iodine by the mammary gland during lactation may reduce the maternal iodine pool in case of inadequate iodine status. 11 In the USA, the reported mean values for increased use of iodine by the bread and dairy industries have caused an increase in consumption of iodine and iodine concentration in mature human milk has varied considerably over the last 50 years.…”

“…The infant also needs a supply of iodine for normal thyroid activity, vital for brain development in the first 2 years of life. The neonatal full‐term thyroid gland contains about 100 µg of iodine under conditions of iodine sufficiency 6 . The supply of iodine to the neonate and infant comes exclusively from breast or formula milk in the first 6 months of life and from milk/formula and complementary foods thereafter.…”

“…The neonatal full-term thyroid gland contains about 100 μ g of iodine under conditions of iodine sufficiency. 6 The supply of iodine to the neonate and infant comes exclusively from breast or formula milk in the first 6 months of life and from milk/ formula and complementary foods thereafter. The iodine demand of newborns is partly supported by thyroid-iodine storage during intrauterine life.…”

Adequate concentration of iodine in breast milk is essential to provide for optimal neonatal thyroid hormone stores and to prevent impaired neurological development in breast-fed neonates. In many countries of the world, low iodine content of the breast milk indicates less than optimum maternal and infant iodine nutrition. The current WHO/ICCIDD/UNICEF recommendation for daily iodine intake (250 microg for lactating mothers) has been selected to ensure that iodine deficiency dose not occur in the postpartum period and that the iodine content of the milk is sufficient for the infant's iodine requirement.

“…Previous publications describe a time-dependent decrease in breast milk iodine concentrations after delivery: highest amounts were detected in colostrum, after which iodine content declined and attained a steady state in mature milk [29,30]. In contrast, Etling et al [31] found significantly increased iodine contents in mature milk compared with colostrum. Comparable to our results, these authors detected quite different levels of iodine concentrations in human milk from one day to another.…”

Iodine balance during pregnancy and lactation was investigated by measuring iodine concentration in the urine of 11 pregnant women, born and living in a moderately iodine deficient endemic goiter area in Northeastern Sicily, collected during the last week of pregnancy, and between the 5th and 7th day after delivery, and in their milk sampled simultaneously with the urine of their newborns. The results were compared with those obtained on similar samples from 16 euthyroid age-matched nongoitrous women and their offspring from an iodine sufficient area. Urinary iodine concentration in pregnant women from the endemic area (1.28 +/- 0.13 micrograms/dl, mean +/- SE) was significantly lower than that of pregnant women from the iodine sufficient area (3.77 +/- 0.57 micrograms/dl) (t = 3.56, p less than 0.005). The longitudinal measurement of iodine concentration in each nursing woman showed a marked increase (approximately 90%) when compared with the values obtained during pregnancy in both endemic and control groups (2.32 +/- 0.36 and 7.76 +/- 2.08 micrograms/dl; t = 2.13 p less than 0.05, respectively). The slight difference in milk iodine concentration between the endemic (3.25 +/- 0.77 micrograms/dl) and the control (4.33 +/- 0.57 micrograms/dl) group was not statistically significant (t = 1.14; p less than 0.5, NS). Similarly no difference was found in urinary iodine excretion between the endemic and the control newborn groups (3.41 +/- 0.76 and 4.30 +/- 0.65 micrograms/dl, respectively, t = 0.88 p less than 0.1, NS).(ABSTRACT TRUNCATED AT 250 WORDS)
