Not knowing much about the biochemical effects of iodine: is it possible Western people need less iodine? Northern Europeans evolved to have lighter skin because they needed more Vitamin D from the limited sunlight. I wonder how much genetics play a part in what defines the "ideal state".

Since the identification of the widespread deficiency and it's effects which motivated iodization of salt was first in the West among Western people, probably not meaningfully. Unlike sunlight which is highly latitude dependent, iodine availability is much more location dependent, and the high availability places (places with access to fish, approximately—both saltwater and many freshwater locations) are also where pre-civilization human populations tended to be most concentrated.
