Why is the use of iodised salt advisable?

Answer: The use of iodised salt is highly recommended due to its significant health benefits, particularly in preventing iodine deficiency disorders. Here are several reasons why iodised salt is advisable:

1. Prevention of Iodine Deficiency

Iodine is an essential trace element required by the body to produce thyroid hormones. These hormones are crucial for various bodily functions, including metabolism, growth, and development. Iodine deficiency can lead to a range of health issues, such as:

  • Goiter: An enlargement of the thyroid gland, resulting in a visible swelling in the neck.
  • Hypothyroidism: A condition where the thyroid gland does not produce enough hormones, leading to symptoms like fatigue, weight gain, and depression.
  • Cretinism: Severe iodine deficiency during pregnancy can cause congenital hypothyroidism in newborns, resulting in intellectual disabilities and growth retardation.

2. Supporting Cognitive Development

Adequate iodine intake is crucial for brain development, especially during pregnancy and early childhood. Iodine deficiency during these critical periods can lead to irreversible cognitive impairments and reduced intellectual performance. Ensuring sufficient iodine intake through iodised salt helps in promoting optimal cognitive development in children.

3. Enhancing Metabolic Function

Thyroid hormones, which require iodine for their synthesis, play a vital role in regulating the body’s metabolic processes. These hormones influence the rate at which the body uses energy, synthesizes proteins, and manages fat stores. By using iodised salt, individuals can help maintain proper thyroid function and, consequently, a healthy metabolism.

4. Preventing Other Health Issues

Iodine deficiency has been linked to various other health problems, such as:

  • Infertility: Both men and women may experience fertility issues due to inadequate thyroid hormone levels caused by iodine deficiency.
  • Increased Risk of Miscarriage and Stillbirth: Pregnant women with iodine deficiency are at a higher risk of miscarriage, stillbirth, and other pregnancy complications.
  • Impaired Immune Function: Iodine is also known to support the immune system, and deficiency can lead to a weakened immune response.

5. Cost-Effective Public Health Measure

Fortifying salt with iodine is a simple, cost-effective public health strategy to combat iodine deficiency on a large scale. It requires minimal changes to existing salt production processes and helps ensure that the entire population receives adequate iodine intake through their regular diet.

Conclusion

The use of iodised salt is a practical and effective measure to prevent iodine deficiency and its associated health problems. By incorporating iodised salt into daily diets, individuals can support their thyroid function, cognitive development, metabolic health, and overall well-being. Therefore, it is highly advisable to use iodised salt as a preventive health measure.
