Many contemporary salt preparations do not contain much iodine, and there are renewed concerns about the iodine status of the population. We present a boy with severe allergy who developed goitre and significant thyroid dysfunction in association with an iodine-deficient ‘food-restricted’ diet. The case highlights the importance of a comprehensive nutritional assessment in all children on multiple food restrictions.
