It is only Type II Diabetes that can be helped through diet though, right?
Type I is where an auto-immune condition where the body attacks itself, in this case the pancreas' ability to produce insulin is attacked.

I hope that somewhere out there is a natural solution to auto-immune conditions of all types, but I don't think eating healthy makes enough difference. Perhaps there are certain super foods that are more medicine than food, that can help an auto-immune condition.
