Why Is the Use of Iodised Salt Advisable?

Iodised salt is recommended because it provides a vital trace mineral—iodine—which is essential for the production of thyroid hormones in the human body. These hormones regulate metabolism, growth, brain development, and many other critical functions.

Iodine deficiency can lead to goitre (enlarged thyroid gland), intellectual disabilities in children, and various metabolic disorders. Since natural iodine content in food and water varies widely, especially in inland and mountainous regions, adding iodine to salt ensures that the population receives an adequate amount.

Real-World Example

India, with large populations living far from the sea, has historically faced widespread iodine deficiency. The introduction of iodised salt has significantly reduced the incidence of goitre and related health problems.

Actionable Insights

• Use iodised salt in daily cooking to prevent iodine deficiency disorders.
• Pregnant and breastfeeding women should be especially vigilant, as iodine is crucial for fetal and infant brain development.
