Iodised salt contains a very small amount of iodine added to prevent iodine deficiency. When heated during cooking, the iodine content in iodised salt does not vaporize or sublimate significantly to create a health concern. Hence, the amount of iodine present in the food after cooking from iodised salt is negligible and safe.
