Sea vegetables are not only a fantastic source of iodine, but possibly a unique source of vanadium. Reading up, vanadium appears to play a multi-faceted role in regulation of carbohydrate metabolism and blood sugar.
If somebody with a better grasp of biochemistry than me (that's everyone, then) can offer further insight, I'd be very grateful. Let's hear from you in the comments.
