Dear astoner613,
your daughter's chances will be greatly decreased if she is given a proper diet. Many individuals feel victimized by diseases that are largely preventable. Type ii diabetes used to be called "adult onset diabetes," but they had to change the name because so many more children were getting it. I'd like to explain why:
in 1900, the average american consumed 7 pounds of sugar per year. In 2000, the average american consumed 140 pounds of sugar per year. Isn't that scary? And it's not just us topping off our food with spoonfuls of sugar; it's in everything. Stay away from items that contain "high fructose corn syrup" (which is hard, because it's in almost everything processed).
I don't claim to be an expert, but I do know this: shopping the perimeter of the grocery store and introducing your daughter to fresh, raw fruits, vegetables and grains and ridding her diet (and yours!) of processed sugars and flours will help her immensely.
I recommend checking out the book "eat healthy, feel great" by Dr. William sears to help teach your daughter (i'm not sure of her age) about making her own good nutritional choices.
Hope that was of some help. I'd love to hear any comments or questions you might have, but am loathe to post my email address here. Please contact me through my website, listed below. And best of health to you and your family!
