I’d point out that iodine deficiency’s effect on IQ seems to be entirely prenatal—that is, there is a window of vulnerability during a human’s development, and once they’re past that, iodine deficiency no longer operates on IQ (for better or worse) and all that’s left are more minor effects like reducing goiters. Seems possible that a lot of nutrients are like that: main effects of deficiency are in childhood/infancy/prenatal.
Severe iodine deficiency tends to be much more common in diabetic patients, and hypothyroidism (most commonly caused by iodine deficiency or hashimoto’s thyroiditis) tends to be comorbid with diabetes.

When my iodine levels get low I develop symptoms of diabetes. Sushi can induce insulin shock/hypoglycemia in me.
It screws with my hunger and thirst levels as well.
Apparently I’m not alone, either; there seems to be some evidence that there’s a link between iodine and diabetes more generally.
Could you please post or link to it?
