Io­dine in Salt – the First For­ti­fi­ca­tion

Consumer Voice - - Project In Focus -

Dur­ing the 1921 Amer­i­can Med­i­cal As­so­ci­a­tion (AMA) con­ven­tion, two Ohio doc­tors pre­sented find­ings from their clin­i­cal trial demon­strat­ing the ef­fec­tive­ness of sodium io­dide treat­ments for the preven­tion of goitre. It was found that with­out io­dine the body could not prop­erly syn­the­size thy­roid hor­mones, which of­ten re­sulted in an un­sightly neck goitre or in more se­ri­ous cases, men­tal re­tar­da­tion. Io­dine de­fi­ciency gen­er­ally oc­curs in ar­eas where the soil has been de­pleted of io­dine be­cause of flood­ing, heavy rain­fall, or glacia­tion. Shortly af­ter the pub­li­ca­tion of the re­sults, Michi­gan be­came the first state to in­sti­tute a pub­lic cam­paign to pro­vide di­etary io­dine via salt. An ex­ten­sive ed­u­ca­tional cam­paign that in­volved school­teach­ers, in­dus­try as well as med­i­cal and pub­lic health com­mu­ni­ties helped in­crease con­sumer aware­ness about, and de­mand for, iodized salt so that by 1924 iodized salt was com­mon­place, de­spite the fact that iodiza­tion was never manda­tory. Epi­demi­o­log­i­cal stud­ies fol­low­ing the im­ple­men­ta­tion recorded a sig­nif­i­cant de­cline in the in­ci­dence of goitre, con­firm­ing the suc­cess of the pro­gramme. Most ta­ble salt con­tin­ues to be for­ti­fied with io­dine to­day.
