Iodine – An Essential Micronutrient!


Iodine – An Essential Micronutrient

Iodine is an essential micronutrient, which is required in very minute quantities for the body.  It is essential for the synthesis of a hormone produced by thyroid gland, which is situated in the neck region.


  • The wide spectrum of disorders caused by inadequate iodine consumption are known collectively as Iodine Deficiency Disorders(IDD). These include:
    • Lowering of IQ and impaired learning.
    • Energy loss
    • Reproductive losses like increased miscarriages, increased stillbirths.
    • Cretinism includes Mental retardation, Deaf – mutism, Squint, Dysplegia (spastic paralysis of the lower limbs), Dwarfism, Coordination abnormalities.
    • Goitre – the most visible manifestation (enlargement of thyroid gland resulting in swelling of front portion of neck).
    • Reduced milk, egg, meat and wool yields in animals.
    • Reproduction failure in animals.


  • Deficiency of iodine in pregnant women can cause irreversible brain damage in the unborn baby.
  • Iodine deficiency is the leading cause of preventable mental retardation in the world.
  • Current research indicates that iodine deficiency results in lowering the average intelligence of the entire school age population by as much as 10 to 15 IQ points.
  • IDD is preventable.
  • Daily Consumption of iodised salt prevents the spectrum of disorders caused due to iodine deficiency.

Hence use only Iodised salt in cooking and for animal feed
