Iodine is an essential element that enables the thyroid
gland to produce thyroid hormones.
Three iodine molecules are added to make T3 (triiodothyronine),
and four for T4 (thyroxine) -- the two key hormones produced by
the thyroid gland -- so iodine is essential to the production of
these two hormones of the master gland of metabolism.
One needs the proper amount of iodine for optimal thyroid
function.
Iodine is required for
Iodine is used in the production of hormones (such as thyroxine,
thyroxin) by the thyroid gland, which in turn regulates the
conversion of fat to energy, stabilizing our body weight as well as
controlling our cholesterol levels.
These hormones produced from the iodine are also needed to
help form our bones, as well as keeping our skin, nails, hair and
teeth in prime condition.
Some indication also exists that iodine is helpful in preventing
cancer of the breast and womb.
Severe iodine deficiency may manifest itself by Cretinism i.e.
children born with severe hypothyroidism. Neonates and young
infants constitute the target population for the effects of iodine
deficiency because, from a public health viewpoint, the most
important complications of iodine deficiency are irreversible brain
damage and mental retardation which result from iodine
deficiency and thyroid failure during fetal and early postnatal life.

Mild iodine deficiency has been reported to reduce intelligence quotients (I.Q.) by 10-15% (15, 25, 81) and cause increased
rates of stillbirths, perinatal mortality, and infant mortality (36, 54). There is good evidence from community-based
assessments and iodine intervention trials that IDD can leave entire populations with below average intelligence and irnpaired
motor functions. Iodine prophylaxis given before or during pregnancy has resulted in improved cognitive functioning in
offspring in Ecuador (25-27, 81). Iodine supplementation given to school-age children can improve performance on tests of
intellectual functioning (5, 21).
Elevated thyroid uptake due to iodine deficiency aggravates the risk of thyroid irradiation and development of thyroid cancer in
the case of a nuclear accident. Even in Europe, clinically euthyroid school children born and living in an iodine deficient
environment exhibit subtle or even overt neuropsychointellectual deficits as compared to controls living in the same ethnic,
demographic, nutritional and socio-economic system, except that they are not exposed to iodine deficiency.
For almost eighty years, iodized salt has been used as the simplest and most effective way of providing extra iodine in the
diet. Iodine is most often added in the form of potassium iodide, but iodate is preferred in humid regions owing to its greater
stability. Many countries have long since introduced iodized salt which resulted not only in a dramatic reduction in the
prevalence of goitre but also progressive disappearance of endemic Cretinism. In the United States and Canada, one part of
iodide is added to 10,000 parts of salt. In other countries, the ratio is one to 100,000. Iodination of water has been
successfully used in some areas with adequate water supply and control of the iodination process. Iodination of irrigation
water has been successfully used in China.
Iodine is rapidly eliminated from the body, so high intake or toxicity is not very likely, but if your diet is supplement with too
much kelp or iodine you could have problems with acne or skin rashes.
If you have an under-active thyroid try and avoid large amounts of raw cabbage, peaches, pears, spinach and Brussels
sprouts as they may block the absorption of iodine.
Iodine is found in eggs, milk, sea fish and sea food, sea vegetables - such as kelp, asparagus etc.
