Salt iodization

Salt iodization is a process of adding a small amount of iodine—a nutrient essential for healthy thyroid function—to table salt. This simple method ensures that people receive adequate iodine in their diet, which is crucial for proper growth, brain development, and preventing disorders like goiter. Since salt is widely consumed and affordable, iodizing it is an effective and cost-efficient way to address iodine deficiency globally, helping improve overall health and prevent related health problems across populations.
