Why is iodised salt important in our diet, and how does iodine relate to the synthesis of thyroxin hormone?

Iodized salt is crucial in our diet as iodine is essential for the synthesis of thyroxine, a key thyroid hormone. Thyroxine regulates metabolism, growth, and development. Iodine, obtained from iodized salt, is incorporated into the structure of thyroxine. Without sufficient iodine, the thyroid gland cannot produce an adequate amount of thyroxine, leading to thyroid disorders like goiter and hypothyroidism. Iodized salt ensures a consistent and accessible source of iodine, preventing iodine deficiency disorders and supporting proper thyroid function, which is vital for overall health, energy metabolism, and the development of the nervous system, particularly in pregnant women and infants.
