The Claim
The Tolerable Upper Intake Level of iodine is set at 250 μg/day for children aged 7–10 years and 300 μg/day for children aged 11–14 years based on observed associations between iodine intake and goiter risk, though these thresholds are not proven to prevent harm.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Children aged 7 to 10 should not consume more than 250 micrograms of iodine per day, and children aged 11 to 14 should not consume more than 300 micrograms per day, because higher intakes have been linked to goiter in observational studies, though it is not confirmed that these limits prevent harm.
See the scientific wording
The recommended Tolerable Upper Intake Level of iodine for children aged 7–10 years is 250 μg/day and for those aged 11–14 years is 300 μg/day, based on observed associations between iodine intake and goiter risk, though these thresholds are not proven to prevent harm.
When too much iodine enters the body, the thyroid gland gets overwhelmed and stops making hormones properly. This causes the gland to swell up as it tries to fix the problem.
What the research says
1 studyThis study found that when kids aged 7–10 eat more than 250 micrograms of iodine a day, or kids aged 11–14 eat more than 300 micrograms, their thyroids start to swell (goiter). So the safe limits mentioned in the claim are backed by real data from kids in China.
