I don't think anyone who is in the know would be surprised about that. Noninvasive blood glucose monitoring is a multi billion dollar product, should anyone be able to figure it out at all. It's fiendishly difficult, and quite possibly impossible to do it sufficiently accurately, even more so over long periods of time. C8 MediSensors was trying to do it 10 years ago, but ultimately went under. Even with Apple's budget, it's a herculean task.
