For anyone interested in this area, I would highly recommend following the work of Iodine Global Network (and donating if possible). They work with politicians and industry in a very targetted way to increase the use of iodised salt in food production where it is most needed in the world. They don't directly fund any of the activities, but create the relationships, conditions and understanding for it to happen - meaning they are an extremely effective charity, creating population scale change with very modest funding. They also do lots of work to try to map the global picture of iodine intake from the very varied data available. Some of the results might surprise you - https://ign.org/scorecard/ https://ign.org/scorecard/
