One thing about this “sugar = diabetes” thing is that people hyper focus on just sugar. Insulin acts on all digestible carbohydrates, not just sugar. Vegetable starch such as rice, corn, wheat or potatoes is just a chain of glucose molecules and is actually turned into blood glucose faster than sucrose. Eating 1 lb of potatoes is exactly the same as eating 1/4 lb of sugar, other than that it comes with some oil too.
Also it sure is annoying having type 1, which has nothing to do with that, and type 2, which does, is 24x as common.
