Iodine Deficiency 2019: The Disaster Continues

Dr. David Brownstein examines the continuing disaster of iodine deficiency.

In medical school, I was taught that iodine deficiency was a thing of the past. It took me a short time into my holistic practice of medicine to realize that what I was taught about iodine was incorrect. In fact, I have been writing about iodine and its importance to health for nearly 15 years. When I started researching iodine in the late 1990s, I was shocked to discover that iodine deficiency was still occurring across the United States. When I began testing my patient’s iodine levels I found the vast majority—over 97%–were iodine deficient and most were severely iodine deficient. Read more

The Iodine Deficiency Epidemic

The iodine deficiency epidemic results in childhood neurological disorders and cancer, says David Brownstein MD.

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
