Iodine deficiency trends in the United States

Overview

Recent research indicates a decline in iodine levels among the United States population, representing a regression in public health nutrition. Data from 2017 and 2018 shows that 24 percent of women and 30 percent of men aged 14 and older were not receiving adequate amounts of the nutrient, which is approximately double the deficiency rates recorded in 2001 and 2002.

The shift toward using specialty salts, such as Himalayan or sea salt, instead of iodized salt may be contributing to this nutritional gap. This trend is particularly concerning for pregnant women, nearly half of whom are not consuming sufficient iodine. Elizabeth Pearce, an endocrinologist at the Boston University Chobanian & Avedisian School of Medicine, noted that even mild iodine deficiency during pregnancy can be associated with “lower IQ in children.”
