Reply to comment by KSMO in TIL A 2017 study found that the introduction of iodized salt in 1924 raised the IQ for the one-quarter of the population most deficient in iodine. by kstinfo

I was shocked to find that a huge fast food franchise I worked for in high school had only non-iodized salt. Restaurants were supposed to be the main place to disseminate it to everyone, but I get the impression that either cost or taste is reducing how many places buy iodized salt.
