When I opened it I was shocked to see it. It definitely wasn't what I expected. I don't understand how the producer of the piece illogically assumes that diet drinks = diabetes. There are other factors involved besides one specific dietary item. It's a flawed logic.
I know they think they are being cute but still, it's as Sarah and David said uncomfortable and disturbing.
Note: I couldn't type all this when I posted the video last night because I was on my smartphone--today I'm on my desktop computer. So I'm able to vent (albeit late).
