About this trial
Iodine as an essential trace element for human, both excessive and insufficient intake would be harmful for human health. As susceptible population, children will be more sensitive to adverse effects caused by inadequate intake of iodine since they are at the peak of growth and development. Meanwhile, there are few direct evidence to establish dietary intakes levels of iodine for 3-6 years old pre-school children.
