World Iodine Deficiency Day 2020: All you need to know
World Iodine Deficiency Day 2020: World Iodine Deficiency Day is also known as Global Iodine Deficiency Disorders (IDD) Prevention Day. We all know that minerals and vitamins are necessary for our healthy life and play a crucial role in the physical and mental development of humans. Iodine is a mineral that is found in some foods.
What is Iodine and why it is necessary for our body?
Iodine is stored in the thyroid gland of our body and is an essential dietary mineral. It is important for our body as it helps in the production of thyroid hormones thyroxine (T4) and triiodothyronine (T3). Let us tell you that hormones of the thyroid gland affect mostly all the cells in the human body and are also important for the proper development of cells. It also helps in protein metabolism, increases the metabolic rate of the body, regulates the growth of bones and development of the brain. Basically, thyroid hormones regulate protein, fat, and carbohydrate metabolism in cells.
What is Iodine Deficiency Disorder (IDD)?
As the name suggests, the deficiency of iodine in the body may lead to serious illness. It can start before birth, jeopardise children's mental health, and often their very survival. During pregnancy, a serious deficiency of iodine can result in stillbirth, spontaneous abortion, congenital abnormalities like cretinism, mental retardation, etc. As we have discussed above, iodine is required for the synthesis of thyroid hormones, thyroxine (T4) and triiodothyronine (T3). It is also, essential for the normal growth and development of humans.
Deficiency of Iodine
- Mental retardation
- Subnormal intelligence
- Neuromuscular weakness
- Defect in vision, hearing, and speech
- Intrauterine death etc.
Sources of Iodine
- Sea Fish
- Cereal grains
- Sea vegetables
- Vegetables and Fruits etc.
WHO regarding IDD
WHO, since 1980s has been working for public health around the world and also to eliminate the deficiency of iodine. For this WHO provides guidelines, technical tools, methodologies, and technical guidance to build up national salt iodization programmes.
UNICEF, ICCIDD (International Council for Control of Iodine Deficiency Disorders), some international and bilateral agencies are also together working to combat with iodine deficiency. We can't ignore that various salt agencies have helped countries to set up permanent national salt and iodization programmes.
In 1993, for controlling IDD, a primary intervention strategy that is universal salt iodization was adopted. Salt is widely available and consumed in regular forms throughout the year so, it is chosen and the cost of iodizing is also extremely low per person per year.
In most of the countries where iodine deficiency is a public health problem, strategies are implemented against IDD.
Some facts regarding Iodine Deficiency
- Iodine deficiency can cause impaired cognitive development in children.
- Countries, where iodine deficiency is a major concern, has been halved now from the past according to a new global report on iodine status.
- According to WHO, approx 54 countries are still iodine-deficient.
- Sustainable salt iodization programmes are necessary to strengthen.
So, we can say that it is necessary to take iodine in our diet. But excess of everything is bad. It should be taken in proper quantity as required by our body.
