Story: Salt



Goitre is a condition where the thyroid gland in the neck enlarges due to iodine deficiency. It was relatively common in New Zealand until the 1920s, when there was a public health initiative to fortify salt with iodine. This proved very successful, and goitre virtually disappeared within a few decades. Yet in the 1990s, research showed that a significant number of people were slightly deficient in iodine. This was thought to be the result of food manufacturers using non-iodised salt in their products, changes in dairy product manufacture, and a trend towards using speciality salts that do not contain iodine in cooking.
