Iodine is a trace element that is naturally present in foods and is added to some types of salt. Iodine is an essential component of thyroid hormone which plays a key role in digestion, heart and muscle function, brain development and maintenance of bones.

In this podcast, I’ll look at the roles of iodine, where it is found in food and what are the health issues with not getting enough of it.
