Iodine fortification programs

Iodine fortification programs involve adding iodine to common foods, typically salt, to prevent iodine deficiency. Iodine is essential for healthy thyroid function and brain development. When populations consume adequately iodized salt, it helps reduce disorders like goiter (enlarged thyroid) and cognitive impairments caused by iodine deficiency. These programs are a practical public health intervention to ensure all individuals get enough iodine through their regular diet, especially in regions where iodine deficiency is common due to lack of naturally iodine-rich foods or soil depletion.
