Just my two cents, but as a type 1 diabetic: I either want very accurate blood sugar readings, or none at all.
And from what I know about people who don't suffer from diabetes: there is almost no reason to try and find out what your blood sugar is doing, because your body regulates it so well.
So I just don't see the point of this. Non-invasive glucose monitoring just doesn't seem feasible, the accuracy doesn't help diabetics and it certainly doesn't help non-diabetics.
I'm a naysayer on this, but I do hate having to continuously test my sugar and buy expensive CGM gear. Please prove me wrong?
