A century ago, iodine deficiency was a widespread problem in the US, causing goiter, stunted growth, and intellectual disability in children. However, after adding iodine to table salt and bread in the 1920s, it largely disappeared.
Today, experts worry that iodine levels are dropping again due to changes in diet and food manufacturing. Most people still get enough iodine from their diets, but pregnant women and children are vulnerable to deficiency.
The American Academy of Pediatrics recommends 150 micrograms of iodine per day for pregnant and breastfeeding women. However, many prenatal vitamins lack this essential nutrient. A study found that a quarter of pregnant women in one city were not getting enough iodine.
Iodine deficiency can cause goiter, lower IQs, and language delays in children. Experts say there hasn’t been enough research to establish its impact on the US population, but cases are being reported, especially among patients with restricted diets.
As concerns grow, doctors stress the importance of checking labels to ensure pregnant or breastfeeding women are taking iodine-rich supplements. With over 50% drop in US iodine levels since the 1970s, it’s crucial to address this issue before it’s too late.
