For nearly 100 years, it has been known that insufficient iodine levels can lead to lowered IQ levels in children. Australian researchers studied whether children born to mothers with mild iodine deficiency during pregnancy have poorer educational outcomes in elementary school as compared to peers whose mothers did not have mild gestational iodine deficiency. All of the children grew up in an “iodine-replete environment”—that means they had access to iodized salt and other dietary sources of iodine which are thought to maintain iodine sufficiency. The children were followed for nine years where they were assessed with standardized tests.
The researchers found that nine years later, as compared to children of mothers who did not have mild iodine deficiency in pregnancy, mildly iodine-deficient pregnant women’s children experienced significant reductions in spelling, grammar and English literacy. Read more
