Diabetes, can it be fought and won?

I believe it can. Back when I was 20, I had symptoms of diabetes. Got the low sugar headaches and everything. Now after I changed my diet and regularly exercise, I no longer have those symptoms.
Diabetes is hereditary yes. However I think it is also due to poor diet management. In the earlier stages, one can modify diet to rid ones self from the trouble outcome. If someone can identify the symptoms early and prevent further damage to the body through proper diet this can be achieved. I'm living proof.
