Even mild iodine deficiency causes intellectual impairment in children
January 27th, 2010
Several recent studies have shown that New Zealanders again have as high a prevalence of low iodine status as prior to the 1950swith many of all ages across the population being below WHO minimum levels. Since there has been no obvious recurrence of goitre or functional consequences, one might wonder whether the finding is of real significance, although it has been taken sufficiently seriously that as of the end of September 2009 iodine is added to almost all bread.
