Sugar intake is not listed amongst the environmental risk factors for Insulin Resistance:

The biggest controllable risk factor for Type II Diabetes is obesity. This finding has been confirmed by numerous studies.

I don't really care about sponsors, but for those who do, Splenda and Equal both sponsor the American Diabetes Association as well.

I'd say that those two companies would much prefer for the ADA to declare sugar a cause of Type II Diabetes.
