Study type | Interventional |
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.
