Almost 19 million babies globally are at risk of developing brain damage each year due to a lack of sufficient iodine during pregnancy, The Guardian reports. In the first 1,000 days after conception, iodine deficiency can lead to neurological and psychological development difficulties.

Global context: Some countries are at risk of iodine deficiency problems throughout their populations because the mineral isn’t consistently available in the soil. And, while iodized salt is available to 86% of the world’s households, in Burundi, Mali, Madagascar, Mozambique, South Sudan, and Sudan deficiency is prevalent.
