OBJECTIVE To assess the iodine nutrition and thyroid function of pregnant women, lactating women and infants residing in areas where the Universal Salt Iodization program is in place. METHODS Pregnant women, lactating women and infants were selected randomly in the regions where iodized salt coverage rate is more than 90% since 2000. Urine iodine levels of pregnant woman, lactating woman and ...

Iodine deficiency is uncommon in North America (18). In fact, the issue may be that part of the population is consuming iodine in excess. High levels of iodine in the diet may inhibit the function of the thyroid gland and produce symptoms of iodine deficiency (9). Normal diets are unlikely to supply more than 1,000 μg of iodine per day, and most adults are tolerant to a high iodine intake (1,10...

iodine deficiency disorders are among the most important health problems in iran. use of iodized salt is one of the oldest, most convenient and cheapest ways of idd control, although not very easy to implement. factors such as the chemical form of iodine, heat moisture, light and storage affect its stability. in this survey, salt iodine content at production site and the effect of heat, moistur...

The study by Condo et al. in this issue of the British Journal of Nutrition assessed the utility of a forty-four-item FFQ for use in determining the iodine intake of pregnant Australian women. This is the first such study designed specifically for pregnancy. A strength of the study was the administration of the FFQ at two different time points in gestation, which allowed for assessment of the r...

Iodine deficiency disorders were prevalent in China until the introduction of universal salt iodization in 1995. Concerns have recently arisen about possible excess iodine intake in this context. To document iodine intake and the contribution from iodized salt in China, we surveyed dietary iodine intake during China's nationally representative 2007 total diet study (TDS) and during an additiona...

a spectrophotometric study concerning the interactoin between iodine and bromine with tetrabutylammonium iodide (tbai), tetrabutyl- ammonium bromide (tbabr) and cryptand 222 (c222) has been performed in dichloromethane solution at 25°c. the results are indicative of the formation of tba+x3- and  c222x+x3-  through equilibrium and formation of c222x+x-  through nonequilibrium reactions. the stab...

BACKGROUND If children and pregnant women in the population are iodine sufficient, it is generally assumed infants are also sufficient. But weaning infants may be at risk of iodine deficiency because iodized salt contributes little dietary iodine during this period. To fill this gap, iodine fortification of infant formula milk (IFM) and complementary foods (CF) is likely important. OBJECTIVES...

IODINE IS A TRACE ELEMENT THAT IS FUNDAMENTAL FOR HUMAN HEALTH its deficiency affects about two billion people worldwide. Fruits and vegetables are usually poor sources of iodine; however, plants can accumulate iodine if it is either present or exogenously administered to the soil. The biofortification of crops with iodine has therefore been proposed as a strategy for improving human nutrition....
