World Iodine Deficiency Day: 21st October

World Iodine Deficiency Day

World Iodine Deficiency Day is observed every year on October 21 to raise awareness about iodine deficiency and its impact on human health. Iodine is an essential micronutrient required for the production of thyroid hormones, which regulate metabolism, growth, and development. Lack of iodine can lead to goiter, mental retardation, developmental delays, and other thyroid-related disorders. The day aims to educate people about the importance of iodine-rich foods like iodized salt, seafood, dairy products, and eggs. Governments and health organizations use this day to promote iodine supplementation programs and encourage preventive measures to ensure healthy communities worldwide.
