Iodine Mineral - Iodine Sources - Iodine Deficiency
The Iodine Mineral is one of the family of trace minerals and as such, the body does not require large amounts
of Iodine. However, the Iodine mineral is a very important element of several key body functions. In fact, Iodine
was deemed to be so important that the US government passed legislation recommending that Iodine be added to table
salt to ensure that Americans got an adequate supply of this essential mineral.
As the iodine mineral is ingested, 75% of this mineral makes its way to the thyroid gland. Once there, iodine
joins up with two important hormones that are produced by the thyroid gland: triiodothyronine and thyroxine. Every
part of the body requires these hormones. Most importantly, they play a role in the body's ability to produce
energy. These hormones control and regulate basal metabolic rates. In other words, they determine how fast and how
efficiently the body is able to burn calories.
Thyroid hormones are also what helps control a child's mental development and overall growth rate. Pregnant
women who do not get enough iodine increase the risks that their newborn babies will develop some degree of mental
If you ever had a bruise or cut as a child, your parent likely applied iodine to the affected area. That's
because iodine is an effective antiseptic. In addition to helping clean and heal wounds, it will discolor the skin.
Iodine is also used in hospital operating theatres for it's antiseptic qualities.
For those times when secretions build up in the lungs, iodine is used to thin them, making these secretions much
easier to expel.
Individuals with iodine sensitivity may experience skin problems such as a rash or ulcers in the mucous
membrane. They also may develop a fever and neck swelling.
Iodine is added to most table salt so people generally get the required amount from just one teaspoon of iodized
salt. Other Iodine sources include seafood and sea plants such as kelp and seaweed. Fruits and vegetables grown in
coastal regions are other good sources of iodine. Processed foods are not a good source of iodine as they typically
are not made with iodized salt.
The recommended daily allowance for adults is 150 micrograms/day. Women who are pregnant or who are breast
feeding require more: 157 micrograms/day and 200 micrograms/day respectively.
Since iodine plays a role in producing energy, the most notable symptoms of a deficiency include lethargy,
slowed reflexes and a slowed metabolic rate. Skin can become dry and hoarseness can develop in the throat. The
amount of fat in the blood supply can increase which is why obesity is one of the symptoms of an iodine deficiency.
If the deficiency continues for a long time, the thyroid gland can become enlarged. An enlarged thyroid gland is
called a goiter. A goiter develops when the thyroid gland is forced to work extra hard to produce adequate levels
of thyroxine. Goiters usually protrude from the side of the neck. In children, a deficiency of iodine may cause
mental retardation. Fortunately, this type of deficiency is rare in developed countries.
