Iodine is an essential component of the hormones produced by the thyroid gland. Thyroid hormones, and therefore iodine, are essential for mammalian life. Iodine deficiency is a major public health problem; globally, it is estimated that two billion individuals have an insufficient iodine intake. Although goiter is the most visible sequelae of iodine deficiency, the major impact of hypothyroidis...

To the Editor: Normal thyroid function in fetuses and breast-fed infants, which is dependent on sufficient maternal dietary intake of iodine, is crucial for normal neurocognitive development.1 Children of mothers with severe iodine deficiency may have cretinism. Iodine deficiency affects more than 2.2 billion persons (38% of the world’s population) and is the leading cause of preventable mental...

AIM Objective of this study was to investigate the effect of different levels of iodine supplementation on iodine content of eggs in laying hens. MATERIALS AND METHODS In the experiment, 135 laying hens (White Leghorn) of 55 weeks age were randomly distributed to 5 dietary treatments; each group contained 27 laying hens distributed in three replicates of 9 birds each. Diet T1 was control basa...

Pregnant women are prone to iodine deficiency due to the increased need for iodine during gestation. Progress has recently occurred in establishing serum thyroglobulin (Tg) as an iodine status biomarker, but there is no accepted reference range for iodine sufficiency during pregnancy. An observational study was conducted in 164 pregnant women. At week 16 of gestation urinary iodine concentratio...

In the April issue of The Journal of Nutrition, Andersson et al. (1) published a paper entitled “Global iodine status in 2011 and trends over the past decade,” in which they discuss the status of global daily iodine intake. In this paper, both in Table 1 and in the global map of Figure 5, Greece is incorrectly listed as a country at risk of iodine-induced hyperthyroidism (i.e., median urinary i...

The use of urinary iodine as an indicator of iodine status relies in part on the accuracy of the analytical measurement of iodine in urine. Likewise, the use of dietary iodine intake as an indicator of iodine status relies in part on the accuracy of the analytical measurement of iodine in dietary sources, including foods and dietary supplements. Similarly, the use of specific serum biomarkers o...

Original Article Aims & Objectives : To evaluate distribution of iodine through edible salts and bioavailability of iodine in sub-Himalayan Tarai region of Eastern Uttar Pradesh. Methods & Design: The study has been conducted in all 14 Community development (CD) Blocks in the studied region. To measure the iodine content of salt and water samples ,a total of 490 edible salt samples and 112 drin...

BACKGROUND & AIMS The importance of milk intake to the supply of dietary iodine is not fully known. We therefore undertook a study in Spain of the iodine concentration in cow's milk and the impact of the frequency of milk consumption on urinary iodine concentrations in three study populations. METHODS We studied the iodine concentration in 362 samples of milk from 45 commercial brands and com...

Iodine deficiency during the first two years of life may cause irreversible brain damage and mental retardation. The aim of the present study was to investigate, for the first time, the effect of iodine fortified milk on the iodine status of lactating mothers and their infants. In this multicenter randomized controlled trial, 84 lactating mother-infant pairs from health care centers were random...

Iodine, as a component of the thyroid hormones, is crucial for brain development and is therefore especially important during pregnancy when the brain is developing most rapidly. While randomised controlled trials of pregnant women in regions of severe iodine deficiency have shown that prenatal iodine deficiency causes impaired cognition, less is known of the effects in regions of mild deficien...
