'As Iodine values increased with feeding duration for fat, the differences between sexes became greater.'
Would be interesting to determine that if the REDUCTION of Iodine in the diet of humans, the SIMILARITIES between sexes became GREATER! You see?
I may be out on a rather dubious limb, but could/would Iodine deficiency blur the differences between sexes - i.e., men are less 'masculine' & women less 'feminine'?
