How Can Unhealthy Diet Contributes to Diabetes?

Eating sweets does not… and will never… cause diabetes. It’s a myth that grew legs of its own and ran. Be selective in what advice you heed on here. *However* If you are predisposed to type 2, you can speed up its diagnosis by eating crap and lack of exercise. Contrarywise, you can slow down its onset by eating right and taking care of your health. Sweets plays a part in type 2 onset, but in itself will never cause the disease. Type 2 is primarily genetic, so if there is type 2 diabetes in your family, you should be careful with food and lifestyle choices, you may be predisposed. Eating right is never a bad idea! Type 2 is not as direct as type 1 in its target, and cousins, nephews and grandchildren are all within its reach.

A healthy/unhealthy diet will never play a role in type 1. Type 1 diabetics become such due to genetics (very direct – parent/child, sibling/sibling); your body erroneously identifies the insulin making cells (islet cells) as enemy or foreign cells, and destroys them… kind of the way they do when you have a cold… it's why your cold goes away. This is often, but not always, preceded by an indeterminate virus. By indeterminate, I mean it's not the same virus from person to person, nor is the length of time between virus and diabetes onset.

I don't know why mystical was downthumbed, he's not that far off.
