The United States began adding iodine to salt in 1924 and that one act changed the nation.
New research indicates after the addition the country’s combined IQ went up nearly 15 points.
It’s long been known that when a pregnant mother is iodine deficient it has an unsettling effect on the fetus.
Lack of the mineral slows mental development and leaves lifelong impairment.
It’s believed some areas of the US were more deficient than others due to the lack of iodine in the water and soil.
People in those areas were also more likely to end up with problems with goiter or thyroid issues.
With every upside of something comes a downside as well.
Some with long term iodine deficiency found themselves with hyperthyroidism.
In a few of those cases there were deaths once iodized salt was added back to the diet.
