Are we neglecting iodine nutrition in South Africa?

Abstract

Micronutrient malnutrition is often referred to as “hidden hunger” and remains a major public health concern in low- and middle-income countries¹. Iodine deficiency is one of the most commonly occurring micronutrient deficiencies², and the leading single cause of preventable mental retardation in the world³. The fortification of salt with iodine is the most cost-effective strategy to ensure adequate iodine intake in a population^4,5. Its implementation around the globe has resulted in a marked reduction in iodine deficiency and related disorders, and is considered a public health triumph⁶. However, continued monitoring and surveillance remain crucial for its success⁷.
