How can extra iodine be added to the food supply?
The easiest way to add extra iodine to the food supply is by replacing non-iodised salt with iodised salt. International guidance and experience show that using iodised salt is one of the best ways to reduce iodine deficiency. Iodised salt has been found to be a suitable substitute for non-iodised salt in the majority of foods tested. In contrast, very little evidence exists for ways to add extra iodine to food other than via salt.
