Filter by:Iodine is one of essential micronutrient for human, both iodine deficiency and excess will be harmful for human health. Children is the susceptible population to iodine nutrition, and studies show that even mild iodine deficiency would affect the growth and development of children, so it is urgent to identify the dietary recommended nutrient intake (RNI) of iodine for children to guide children scientifically and safely supplement iodine. There are few studies about the dietary recommended nutrient intake (RNI) of iodine in children, and present data are old and outdated.
A 4-week study was conducted in 25 Chinese euthyroid women. Unified diets with different iodine contents (cooked with non-iodized salt or iodized salt) were provided in two different periods. The total iodine intake from diet, water and air as well as the total iodine excretion by urine, faces and respiration were monitored and determined, and a total of 300 samples were collected. The sweat iodine loss was also considered. Moreover, the regression curve model between the 24-h iodine intake and 24-h iodine excretion was also established.
In this study, we will evaluate the effectiveness of several doses of oral selenomethionine in raising biomarkers of selenium status including plasma selenium concentrations.
The study hypothesis is that different concentrations of nucleotides' supplementation of an infant formula might affect differently growth and/or other clinical parameters in neonates.
