Iodine is an essential nutrient for human growth and development. The thyroid gland is dependent upon iodine for production of thyroid hormone. It is a common perception that iodine deficiency is not a major public health concern in mainland Australia, with sporadic studies carried out about a decade ago showing average urinary iodine excretion levels of around 200 microg/day. Recent evidence, ...
OBJECTIVES Monitoring of iodine status during pregnancy, lactation and infancy is difficult as there are no established reference criteria for urinary iodine concentration (UI) for these groups; so it is uncertain whether iodized salt programs meet the needs of these life stages. DESIGN AND SUBJECTS The method used in this paper was: 1) to estimate the median UI concentration that reflects ad...
Iodine biofortification of vegetables can become an alternative (to iodized salt) method of introducing this element into human diet. Development of agronomic rules concerning its application requires detailed evaluation of iodine influence on plant physiological and biological processes including mineral nutrition and quality of yield. The aim of the study was to determine the effect of iodine...
This paper presents the latest information about the supply of iodine to meet its requirements in hens of laying type, on the basis of iodine content in egg yolk and about the importance of eggs as an iodine source in human nutrition. The Sandell-Kolthoff method was applied to determine iodine content in the yolk of eggs from 9 large flocks (54 eggs) and 16 small flocks (96 eggs) in 2004, and f...
The World Health Organization (WHO) recently increased their recommended iodine intake during pregnancy from 200 to 250 microg/d and suggested that a median urinary iodine (UI) concentration of 150-249 microg/L indicates adequate iodine intake in pregnant women. Thyrotropin concentrations in blood collected from newborns 3-4 d after birth may be a sensitive indicator of even mild iodine deficie...
PURPOSE Iodine is a trace element of thyroid hormones. Excessive or insufficient iodine intake is associated with various thyroid diseases. Urinary iodine (UI) is a sensitive indicator and a recommended barometer of population iodine intake. In Korea, there has been no available data regarding iodine intake in preschool children. We investigated the iodine intake status of Korean preschool chil...
BACKGROUND Most surveys that assess the iodine status of populations target school-age children, whereas others may target nonpregnant women with the assumption that the iodine status of these groups is representative of other groups in the same population. OBJECTIVE To assess whether the median urinary iodine concentration (UIC) of school-age children or nonpregnant women can be used to accu...
Is the current iodine content in edible salt appropriate for eliminating iodine deficiency in China.
OBJECTIVE This study was designed to measure the urinary iodine excretion of volunteers who daily consumed iodized salt and to evaluate whether the current iodine content in salt is appropriate. A field trial study was then conducted to determine how the salt iodization content should be adjusted, either to prevent iodine deficiency or to avoid excess consumption. METHODS A total of 1,099 vol...
CONTEXT Breastfed infants rely on adequate maternal dietary iodine intake. OBJECTIVE Our objective was to measure breast milk iodine and perchlorate, an inhibitor of iodide transport into the thyroid and potentially into breast milk, in Boston-area women. PARTICIPANTS The study included 57 lactating healthy volunteers in the Boston area. MEASUREMENTS Breast milk iodine and perchlorate con...
Turmeric extract decreased frequency of polychromatic erythrocytes micronuclei induced by iodine-131
Background: Ionizing radia on irradiated from iodine-131 can induce DNA damage and cell death. The cellular DNA damage is the cause of muta on and cancer. The micronucleus assay in polychroma c erythrocytes was applied to assess the radio-protec ve effect of Turmeric extract on genotoxic poten al of iodine therapy. Materials and Methods: Thirty six male albino rats were randomly divided in six ...
