"Iodised salts were developed to create a standard product that would supply iodine to one and all. Since it is required in small quantities, salt proved as an apt carrier as people usually have a standard intake pattern for salt. Consuming iodised salt is not necessary and not consuming it won't necessarily translate into a person becoming iodine deficient. It is similar to the case of vitamin D. Since Vitamin D is naturally present in such few food ingredients, supplements or fortified foods tend to become a more feasible ways to source it," shares Dr. Sunil Sharma, Head of Emergency and General Physician at Pt. Madan Mohan Malviya Hospital, Delhi.
