Can nutella give you diabetes?

I'm 15 and well, I should have taken a closer look into my diet and health because I always eat nutella everyday. 720 g of nutella would be done within one week and I would eat it with bread (2 slices) and usually when I eat it the nutella would ooze out. Sometimes I eat it more than once per day but I'm a very toned (according to my peers) and I dance and exercise with I guess a pretty good diet (could use some more fruits and vegetables). I'm just curious to know though if it does give you diabetes cause... I'll be screwed. And no, my other family members don't have diabetes. Oh and I apologize if this is in the wrong section...
