Why table salt is called iodized salt?
Table salt is iodized (that is, iodine is included via sodium iodide or potassium iodide) because people used to be unable to get enough iodine from their diets, and iodine is necessary for a person's thyroid gland to work properly. Since the thyroid is responsible for growth and immunity, people with thyroid deficiency had dramatic problems including dwarfism and goiter (a lump on the front of the throat where the thyroid gland resides). As a result of these problems, iodine was added to table salt (NaCl). These days, it is actually more likely that a person will develop iodine toxicity (i.e. overdose on iodine) because a typical person's salt intake is SO high above what we need for sodium or iodine. One sign of iodine toxicity is greasy skin and pimples.
Which hormone contain iodine?
Iodine is found in thyroxine.It is secreted by thyroid
What organ of the body requires the most iodine?
Thyroid
What gland needs iodine to function correctly?
The thyroid glands secrete thyroxine which contains Iodine. Moreor less of Iodine content can cause permanent harm to the body like Hopothyroid and Hyperthyroid.
What decaying radioisotope produces xenon-131 through beta decay?
Iodine 131 -> Xe 131 + e-
What are some environmental concerns about using the radioisotope iodine?
Iodine collects in the thyroid. If there is a radionuclide of iodine "loose" then we might end up ingesting it and having it collect in our thyroid. The radionuclide would sit there and irradiate us. That's not good. It's a bad idea to have radioactive iodine in the environment.
What radioisotope used to treat prostate cancer?
Radioisotpes are used to treat the thyroid, especially for those who have hyperthyroidism or Graves' disease. Radioiodine is swallowed by a patient and then it is absorbed by the thyroid. The radioiodine eventually kills thyroid cells. This helps patients with an overactive thyroid by slowing down the production of thyroid hormones.
Can you prevent Thyroid disease?
There are many different thyroid diseases. Most cannot be prevented. Iodine deficiency problems may however be prevented with sufficient iodine intake.
If you have hyperthyroidism which is bad for you iron or iodine?
If you have hyperthyroidism, neither iron nor iodine is bad for you. Excessive consumption of either can be dangerous however, and since iodine is fuel the thyroid uses to produce thyroid hormone, anti-thyroid drugs (ATD's) are used to help the body lower its ability to use iodine in the thyroid. Iodine is necessary for life however, as is iron. For appropriate diagnosis and treatment of thyroid dysfunction, please seek the help of a board certified endocrinologist who specializes in thyroid problems.
How does deficiency of iron and iodine affect your body?
Deficiency of iron will lead to anemia while lack of iodine leads to thyroid problems.
What is the use of iodine in body?
One way is in the endocrine system. The thyroid gland uses iodine from the blood to make thyroxine, which is secreted to regulate metabolism. Radioactive iodine is used in medicine to diagnose thyroid problems. When the the radioactive iodine is injected into the blood, it collects in the thyroid, making the thyroid more visible on radiological scans. Our modern diet sometimes does not supply enough iodine, which is why it is added to most table salt.
How does iodized salt help in preventing thyroid problems?
A small amount of either sodium iodide salt or potassium iodide salt is added. The thyroid needs iodine to make its four hormones and if it cannot get the amount of iodine it needs a person will have low thyroid hormone levels and may develop a goiter. The iodine supplementation in iodized salt reduces the chance of these problems.
Is iodine found in thyroid hormones?
No. Iodine is not found in the thyroid hormones, but Iodine is necessary for the thyroid gland to make thyroxin hormone. Actually yes, iodine is found in the thyroid hormones T3 and T4, the most common forms of thyroid hormone.
Why is iodine important for proper thyroid function?
It is used by the Thyroid gland to produce its hormones called: T1, T2, T3, and T4. If not enough iodine is available for it to produce these hormones a swelling of the Thyroid will develop called "Goiter".
What is the radioactive iodine called used to destroy thyroid cells?
The thyroid processes iodine.
Mineral is responsible for affecting the normal functioning of the thyroid gland?
Iodine is required to produce thyroid hormones.Besides iodine Selenium is also required by the thyroid gland as major co-factors in its function to regulate metabolism.Zinc is required for the production of thyroid hormones.
Does the thyroid hormone require iodine for synthesis?
The United States Food and Drug Administration recommends 150 micrograms of iodine per day for both men and women. This is necessary for proper production of thyroid hormone. Natural sources of iodine include sea life, such as kelp and certain seafood, as well as plants grown on iodine-rich soil. Salt for human consumption is often enriched with iodine and is referred to as iodized salt.11. http://en.wikipedia.org/wiki/Iodine
