Effects of excess iodine on learning function in adult mice - gender
Posted: Tue Jul 23, 2024 5:30 pm
Numerous studies on fluoride in populations with excessive iodine intake claim that fluoride decreases IQ only in males, but these studies failed to account properly for the high iodine consumption (i.e. MIREC studies).
What if the observed differences in IQ are not related to fluoride at all, but rather to excessive iodine ingestion?"

"In the behavioral analysis, female mice showed an increase in learning ability. In summary, although the chronic overdose of iodine does not affect thyroid hormone levels, it may affect cognitive learning function."
