आयोडीन की कमी से होने वाले विकार
In this Class 12 Home Science topic from Public Nutrition and Health, students learn how iodine supports thyroid hormone production, growth, brain development and metabolism. They examine iodine deficiency disorders such as goitre, hypothyroidism and impaired mental and physical development, along with the groups most at risk. The topic also explains prevention through adequately iodised salt, correct storage and use of salt, dietary awareness, and the role of nutrition education and public-health measures in reducing deficiency.

Iodized salt is fortified with iodine, a mineral required to produce thyroid hormones. These hormones help regulate metabolism, growth, and brain development. Regular use of adequately iodized salt can help prevent iodine-deficiency disorders such as goitre, though salt should still be consumed in moderation. Therefore, option C is correct.
Iodized salt is fortified with a controlled amount of iodine, a micronutrient needed for the thyroid gland to make thyroid hormones. These hormones support growth, brain development, and regulation of metabolism. Regular use in the recommended quantity can help prevent iodine-deficiency disorders, including goitre and impaired development. Iodized salt does not add fibre or clean clothing, so option B is correct.
Iodine is an essential component used by the thyroid gland to synthesize the hormones thyroxine (T4) and triiodothyronine (T3). When iodine intake is inadequate, hormone production may fall. The pituitary gland then increases thyroid-stimulating hormone, which can enlarge the thyroid and cause goitre. Therefore, option A is correct; iodized salt is an important preventive measure.
