Iodine

Iodine Iodine is an essential macromineral. Almost half the iodine is found in the thyroid gland which is located in the throat. Iodine is an important component of thyroid hormones, which control energy, metabolism in the body as well as the bodys temperature, reproduction, and growth. It is not found in the body so it is very important that you get about .15 mg. daily. Some foods such as vegetables, grains, table salt, dairy products, and especially seafood are the best sources of iodine.

Breathing in sea air everyday will give you a sufficient amount of iodine to prevent a disease called goiter. There are two types of goiter: toxic and simple. Toxic goiter is caused by excess of thyroxin secretion. Symptoms may include rapid heart beat, tremor, increased sweating, increased appetite, weight loss, weakness, and fatigue. Other symptoms may include eye problems such as staring or protrusion. Goiter affects over 200 million people throughout the world.

96% is caused by iodine deficiency. Goiters are rare in the U.S. and other industrialized countries because iodine is now added to table salt. Iodine affects body functions too. Hair and nail growth are affected by iodine. The brain, skin, speech, teeth, energy production, metabolism, and physical & mental health development are dependent on a well-functioning thyroid gland.

Deficiency symptoms include dry hair, goiter, intellectual disability, paused growth, irritability, nervousness, and obesity. If a pregnant woman takes iodine during pregnancy, the development of goiter will be decreased for both the mother and the child. Iodine is the most efficient treatment for children who have goiter. Iodine does have a down side to it, too. It is not toxic up to 2,000 mcg daily, but it may cause acne. Too much iodine is can link to thyroid cancer.

Some people are sensitive to iodine and may break out in a rash if their iodine intake is excessive. The rash looks like a lot like acne. It disappears when the iodine intake is reduced. Most of the illnesses related to iodine occur on all continents and to people of all ages. People who mostly avoid dairy, seafood, processed food, and iodized salt can become deficient.

Iodine deficiency can cause low thyroid function, goiter, cretinism. Some people who are overweight mistakenly blame their overweight condition on an under active thyroid gland. In the hopes of speeding up their metabolism, they may start taking a supplement or eating sea salt or seaweed. But in very large amounts, iodine can be poisonous. Iodine is used to treat cuts and scrapes on the skin. The human thyroid gland secretes an iodine-bearing hormone called thyroxin.

The body needs iodine as an iodine deficiency causes thyroid trouble. Most table salt is now iodized to supplement the diet. As well, iodine is found in seafood. Iodine is only needed in trace amounts. A good source of this mineral is kelp.

Iodine helps to metabolize excess fat and it is very important for both mental and physical health. Iodine deficiency in children can cause mental retardation. In adults iodine deficiency is related to fatigue, breast cancer, hypothyroidism or cretinism, and weight disorders. Chronic iodine toxicity results when the iodide intake is 20 times greater than the daily requirement. In some areas, particularly Japan, inhabitants consume as much as 50 to 80 mg a day, resulting in high plasma levels.

Some of these people develop goiters. Increased uptake of iodine by the thyroid may lead to inhibition of thyroid hormone synthesis and eventually causes iodide goiter or myxedema. At very high doses of iodide, a brassy taste, increased salivation, gastric irritation, and skin acne may occur. Iodine is the important component of thyroxine, the thyroid gland’s hormone. If there is not enough iodine in the diet, there is insufficient thyroxine, and the pituitary gland responds by releasing more thyroid-stimulating hormone.

This causes enlargement of the thyroid gland. However, a goiter may also be caused by overactivity of the pituitary gland or by overactivity of the thyroid gland itself. Other causes include reduced activity of the thyroid gland, so that the gland swells in order to produce more thyroxine. Some types of drugs can produce a goiter. During adolescence or pregnancy, a goiter may appear as the thyroid gland copes with the body’s need for more thyroxine.

Sometimes a goiter is caused by a tumor on the thyroid gland. Bibliography www.juno.com.
