iodine deficiency = low IQ ?

do not consider this a trivial with iodine requirement for our bodies, can we can besusceptible to mumps, and make babies can inhibit brain development.
The following further information:

IDD is a disease that causes mental retardation, but have very easily prevented.This disease can be called iodine deficiency or iodine deficiency. This disease is so little known by the public and probably still is a neglected problem. Currently an estimated 1.6 billion world population at risk of iodine deficiency, and 300 million suffer from mental disorders caused by iodine deficiency. Approximately 30,000 stillbirths each year, and more than 120,000 babies cretins, ie mental retardation, short body, deaf or paralyzed. 

Most of them have an IQ of ten points below its potential. Among those who were born normal, with a low dietary intake of iodine will be children who lack intelligence, stupid, lethargic and apathetic in his life. Thus, iodine deficiency will cause the poor and undeveloped, while in children cause learning difficulties.

The risk was due to lack of iodine in their diets, and the effect on early brain development. Iodine is an essential element for the formation of thyroid hormones.

The hormone is indispensable for normal growth, mental and physical development, in both humans and animals. The effect is very well known person due to iodine deficiency is goiter, the enlargement of the thyroid gland in the neck area.

From the research data on primary school children. then the notion of iodinedeficiency was far from the only cause goitre alone. That led to the development of the child, including brain development, so the term is currently referred to as”Iodine Deficiency Disorders”or abbreviated as IDD.

Iodine Deficiency

The term IDD describes a new dimension of understanding the spectrum ofiodine deficiency. Result in very broad and poorly in the fetus the newborn,children and adolescents and adults in the population is iodine deficient. As a result of it can be corrected with the iodine.

Iodine requirement

Daily requirement of iodine in food is recommended at this time are:

50 micrograms for infants (12 months).
90 micrograms for children (ages 2-6 years).
120 micrograms for school-age children (ages 7-12 years).
150 micrograms for adults (over age 12 years).
200 micrograms for pregnant and lactating mothers.
There are some opinions that are wrong and a different reality. Opinion is wrong,for example, iodized salt can treat IDD like cretins, but the fact can not be treatedunless GAKY only prevented. Also the wrong opinion, that the iodine is verydangerous to consume, consume iodine fact, through iodized salt is not harmfulin the long term.


Troubleshooting is actually very simple, give one tablespoon of iodine on eachperson in need, and continuous. Because iodine can not be stored by the body in a long time, and only needed in small amounts so that should take placecontinuously.

In areas of endemic iodine deficiency due to soil and crops and grass for cattle feed does not contain enough iodine to be consumed by the locals, then iodinesupplementation and fortification are given continuously very high success rate.

The following explanation of iodine deficiency on growth rate:
Iodine Deficiency in the Fetus

Lack of iodine in the fetus due to iodine deficiency mother. This situation will cause the magnitude of the incidence of stillbirth, abortion, and birth defects, all of which can be reduced by iodine. Due to other more severe iodine deficiency in the fetus which is endemic cretins.

There are two types of endemic cretins, the lot is obtained is of type nervosa, characterized by mental retardation, deaf and dumb, and spastic paralysis in both legs. Instead a rather rare type of hypothyroidism is characterized by thyroid hormone deficiency and stunted.

Recent research has shown, the transfer of T4 from mother to fetus in early pregnancy is very important for fetal brain development. When maternal iodine deficiency since the beginning of her pregnancy then the transfer will be reduced T4 to the fetus before the fetal thyroid gland function.

So the development of the fetal brain is highly dependent on maternal thyroid hormone in the first trimester of pregnancy, when maternal iodine deficiency will result in low levels of thyroid hormones in the mother and fetus. In the second and third trimesters of pregnancy, the fetus is able to make its own thyroid hormone, but due to iodine deficiency in this period it will also result in lack of formation of thyroid hormones, resulting in fetal hypothyroidism.

Iodine deficiency in When Newborn

A very important note at this point, is the thyroid function in newborns is closely linked with the state of the brain when the baby is born. In newborns, the brain has only reached one-third, then continue to grow rapidly until the age of two years. Thyroid hormone formation is highly dependent on the adequacy of iodine, and this hormone is essential for normal brain development.

In developing countries with severe iodine deficiency, the discovery of these cases can be done by taking blood from a vein talipusat immediately after birth to check hormone levels of T4 and TSH. Neonatal hypothyroidism is called, if found T4 levels of less than 3 mg / dl and TSH over 50 mU / mL.

In areas with severe iodine deficiency, more than 50% of the population had urinary iodine levels less than 25 mg per gram of creatinine, the incidence of neonatal hypothyroidism is approximately 75-115 per 1000 births. A very striking, in a mild iodine-deficient areas, the incidence of mumps is very low and no cretins, the incidence of neonatal hypothyroidism decreased to 6 per 1000 births.

Inferred from these observations, when iodine deficiency is not corrected, hypothyroidism will persist from infancy to childhood. This resulted in the retardation of physical and mental development, as well as very high risk of mental disorders. In the population in severe iodine deficiency areas marked by a very striking cretins.

Iodine deficiency in The Children

Research on school children living in iodine deficient areas showed school achievement and IQ less than the same age group who originate from areas of iodine sufficiency. From this we can conclude iodine deficiency resulting in low cognitive skills. All research done in areas of iodine deficiency strengthens evidence of iodine deficiency can cause extensive brain abnormalities that dimension.

In that study also confirmed, with the correction of iodine administration will improve learning achievement of schoolchildren. Determinants of brain levels of T3 and T3 pituitary gland is T4 levels in serum, rather than serum T3 levels, the opposite occurs in the liver, kidneys and muscles. Brain T3 levels are low, which can be demonstrated in mice that lacked iodine, found that low serum T4 levels, will be back to normal when the correction of iodine deficiency.

This condition is called hypothyroidism of the brain, which will cause the stupid and sluggish, this is a sign of hypothyroidism in children and adults. This lethargic state can return to normal when given the correction of iodine, but it is different when the circumstances that occurred in the brain. It occurs in fetuses and infants whose brains are still in their infancy, although given the correction of iodine brain still can not return to normal.

Iodine Deficiency in Adults

In adults, mumps can occur with all its complications, which often happens is hypothyroidism, stupid, and hyperthyroidism. Because of the lump / module in autonomic functioning thyroid gland. Besides these effects, increased uptake of the thyroid gland caused by iodine deficiency increases the risk of thyroid cancer when exposed to radiation.
