The only type of diabetes that is truly hereditary is type one, the type that comes on in childhood. Adult-onset diabetes, which it sounds that your father has, can be mitigated by starting now to to eat healthily, get steady exercise, and not drinking to excess.
You can take steps now to try to prevent diabetes, so years from now it will not be a problem for you.

Agreed. I don’t know about all the specifics of it being hereditary because I’ve been told that some of the traits that can make diabetes more likely ‘are’ hereditary, even if the disease itself isn’t. Adult diabetes like that can definitely be controlled, though.

My father was diagnosed with type 2 diabetes in his 60′s. He is the first diabetic in his family line, he didn’t inherited from anybody. All his life consisted of lots of cocacola, candy, bakery treats (highy procesed grains and sugar mix), alcohol, and all his food was cooked (there was no nzymes left so, on top of it all, his pancreas had to do extrawork to produce more nzymes). He is 74 now and not under medication, he controls it with diet.

I don’t believe I will inherit diabetes type 2, that will depend on my diet, I might inherited a "weak" pancreas. It has been a long time since I change my diet and left the way of eating that I was brought up with. I have children that are growing and is my responsability to feed them with the building blocks necesary to be healthy adults (or at least try) by doing my own reasearch instead of putting our health in the hands of the medical system and health guide or even trust that everything sold at healthfood stores is healthy, I’m all for organic but they even sell stuff with sorbitol,maltitol,etc. Soy products, and microwaveble organic popcorn!!!

Type 2 diabetes is not hereditary but family lifestyle issues and diet may play a part in this. You can reduce your chances of type two diabetes by maintaining a healthy weight, eating a healthy balanced diet and getting regular exercise.
