Iodine deficiency is a lack of the trace element iodine, an essential nutrient in the diet.It may result in metabolic problems such as goiter, sometimes as an endemic goiter as well as congenital iodine deficiency syndrome due to untreated congenital hypothyroidism, which results in developmental delays and other health problems.
Where natural levels of iodine in the soil are low and vegetables do not take up the iodine, iodine added to salt provides the small but essential amount of iodine needed by humans. An opened package of table salt with iodide may rapidly lose its iodine content in high temperature and high relative humidity conditions through the process of ...
The total amount of iodine in the human body is still controversial, and in 2001, M.T. Hays published in Thyroid that "it is surprising that the total iodine content of the human body remains uncertain after many years of interest in iodine metabolism. Only the iodine content of the thyroid gland has been measured accurately by fluorescent ...
Iodine deficiency is the leading cause of preventable intellectual disability, a result that occurs primarily when babies or small children are rendered hypothyroidic by no iodine. The addition of iodine to salt has largely destroyed this problem in wealthier areas, but iodine deficiency remains a serious public health problem in poorer areas ...
T 3 and T 4 are partially composed of iodine, derived from food. [2] A deficiency of iodine leads to decreased production of T 3 and T 4, enlarges the thyroid tissue and will cause the disease known as simple goitre. [3] The major form of thyroid hormone in the blood is thyroxine (T 4), whose half-life of around one week [4] is longer than that ...
You can naturally find it in foods, but the list is pretty limited. Some vitamin-D-rich foods include fatty fish (like salmon and tuna), beef, eggs, cheese, mushrooms and fortified cereals. The ...
Iodine deficiency is the most common preventable cause of neonatal and childhood brain damage worldwide. [11] Although iodine is found in many foods, it is not universally present in all soils in adequate amounts. Most iodine, in iodide form, is in the oceans, where the iodide ions are reduced to elemental iodine, which then enters the ...
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security , or a poor understanding of nutritional requirements. [ 2 ]
