It is estimated more than 500 million people worldwide are iodine deficient particularly those in mountainous regions far from the sea. 

A key sign of iodine deficiency is goitre (a swelling on the neck from the thyroid) as the thyroid gland swells to compensate for a lack of iodine. 

Iodine deficiency in pregnancy can lead to mental and physical retardation of babies.

A common test to see if you are iodine deficient is to paint your feet or another inconspicuous part of the body with Lugol’s Iodine solution. The solution will turn the skin yellow and the time it takes to be absorbed can indicate how deficient your body is of iodine. 

Things you need to know about iodine

Some foods contain goitrogens which  block the absorption of iodine. 

Goitrogenic foods  include cabbage, peanuts, soybeans, turnips and rapeseeds.

However, goitrogens are generally inactivated through cooking.

Halogen elements such as chlorine, fluorine, bromine can also block the absorption of iodine. This is because they are chemically related to iodine which is also a halogen and so are able to displace and block uptake of iodine. 

Bromine is particularly prevalent as an environmental toxin as it used as a fire retardant chemical which can be found in from children clothes to carpets, mattresses to cars etc..
