"Iodine is essential for healthy brain development in the fetus and young child. Iodine deficiency negatively affects the health of women, as well as economic productivity and quality of life," WHO.

"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.
