Iodine Transfer Through Mother s Milk The Influence of Bromide... 

Consequences of a decreased iodine transfer and/or an increased bromide concentration in the mother s milk were ... 

No studies of humans have demonstrated inhibition of iodide transport into breast milk of mothers from thiocyanate in diet. In many countries the most important determinant of thiocyanate levels in blood is tobacco smoking, as discussed above, and smoking is associated with similar increases in thiocyanate in blood as may be found from diets with high cyanide content. We therefore investigated the effect of maternal smoking on iodine transfer to the breast-fed neonate. 

Figure 28.6 Maternal smoking and neonatal iodine nutrition. Breast-milk iodine and infant s urinary iodine content expressed as fraction of the mother s urinary iodine concentration. Both are measures of iodine transfer from mother to child during breastfeeding. The infant s urinary iodine content is expressed as a fraction of miik iodine content and is an inverse measure of iodine retention in the infant.
