The Claim
Thyroid tissue iodine concentrations exhibit high variability (CV% > 15%) among follicles, whereas selenium and zinc concentrations demonstrate lower variability (CV% < 10%), indicating that iodine distribution is functionally dynamic and selenium and zinc distributions are more uniform within thyroid tissue.
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.
In the thyroid gland, iodine levels differ greatly from one follicle to another, while selenium and zinc levels remain relatively consistent across follicles, suggesting iodine is actively regulated in a variable way, whereas selenium and zinc are distributed more evenly.
See the scientific wording
Thyroid tissue iodine concentrations show high variability (CV% > 15%) between follicles, while selenium and zinc concentrations are more homogeneous (CV% < 10%), suggesting iodine distribution is functionally dynamic, whereas selenium and zinc are more uniformly distributed in thyroid tissue.
What the research says
1 studyThe study found that iodine levels in the thyroid change a lot from one tiny gland unit to another, while selenium and zinc stay pretty even — meaning iodine is more active and responsive, while the others are more steady.
