Iodine and the Thyroid Hormone What is Iodine? What role does Iodine play in the body?
Iodine is an essential micronutrient required everyday in very minute quantities (100 — 150 micrograms). Iodine is essential for normal human growth and mental development. Most iodine (around 60%) is stored in the thyroid gland - a butterfly shaped gland at the base of the throat. Thyroid hormones secreted by the thyroid gland control the basic metabolic rate of the body.

If the gland produces too much thyroid hormone, it speeds up metabolism (hyperthyroidism) but if the thyroid hormone is deficient it slows down metabolism (hypothyroidism). Both hypothyroidism and hyperthyroidism can bring about ‘Goiter' — or an abnormal enlargement of the thyroid gland.

Thyroid hormones are vital during pregnancy for proper mental & physical development of the fetus. Deficient thyroxin can cause lowered IQ and brain damage due to diminished nerve cell branching.

Even if people eat a lot of fish and other sources of natural Iodine they can still used iodized salt without any worry as it does not add more than 300 mcg iodine daily to the diet. The fear of consuming excess iodine should not lead to stop use of iodized salt. Iodine excess is undesirable, but its consequences are not nearly so severe as those of iodine deficiency, because the latter affects human development and can produce permanent brain damage. Anyways most people can tolerate at least 1 mg (1000 mcg) of iodine daily without adverse effects, unless they have an auto immune problem.

When my sister was pregnant she was diagnosed as a hypothyroid patient and put onto medication to correct it and have a normal pregnancy. Now her little son needs to take a little pill of thyroxin every day.Will this be needed for life? Will it affect his mental and physical growth?

Hello Prakruthi,
We understand your concern for your young nephew.
Some babies are born with a condition called congenital hypothyroidism. Was that the diagnosis for your nephew? Usually, if the medication the child receives is in the right quantities needed by the body the child should grow normally.
Your sister and her husband must discuss these issues with the doctor and also read a lot about the condition from reliable sites on the internet to be well informed about his condition and keep in touch with any new developments in the field.

We eat sea food regularly in our home especially seer, haddock and pomfret. Do we need to use iodised salt in our cooking?

Hello Vishwa,
If you are getting an average of 150ug of iodine per day through your diet, you are meeting your needs for the nutrient. If not, you will need to consume some iodised salt to cover the deficit.

Hello madam Poonam,I want to clarify a couple of things.How do I know I am getting 150ug of Iodine everyday in my diet? We are fish eaters but we eat only once or twice a week. My wife is a veg she does not eat at all. Secondly we have no choice but to use iodised salt as all salt sold in the market is iodised salt.
However as somebody has commented if we take iodised salt along with naturally rich iodine foods it should not cause toxicity as we can tolerate upto 1000ug of iodine and iodised salt adds 300 ug per day on the high side.This is a consolation.
