Current Affairs - Important Days - Discussion

October 21 is observed as World Iodine Deficiency Day, also known as World Iodine Deficiency Disorders Prevention Day, to raise awareness about iodine deficiency and its effects on human health. Iodine is an essential micronutrient required by the thyroid gland to produce hormones that regulate metabolism, growth and brain development. Its deficiency can cause health problems such as goitre, hypothyroidism and impaired mental development, particularly during pregnancy and childhood. In India, the National Iodine Deficiency Disorders Control Programme (NIDDCP) works to prevent and control iodine deficiency disorders. Using adequately iodised salt is one of the most effective ways to prevent iodine deficiency.
