Nori Nori and More Nori

Why is it that Saya won't eat rice alone but will eat it with nori (Japanese seaweed)?  Is it the salt? Not sure what it is but it's doing the trick. She didn't eat curry rice so I wrapped it in nori and she ate it and the same with the fried rice. She is adamant for it and when she sees her dad with the nori package of cutting it in smaller pieces she gets really anxious.
