Global Iodine Deficiency Disorders (IDD) Prevention Day or World Iodine Deficiency Day is observed every year on 21st October. Iodine is an essential element for healthy life. It is a micro- nutrient element essential to human life. A lack of iodine may lead to mental retardation, goiter, or thyroid disease. When the thyroid gland lacks iodine it may increase the size of the goiter. Vital functions of the human body depend upon a regular supply of iodine.
This day is dedicated to spreading awareness about the dangers of keeping a diet with insufficient amounts of iodine.
