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 population4,5. 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.
