That's a weird pamphlet. It goes on to say sugary soda increases risk because it's calorie and carbohydrate high.

I get that "cause" is too strong, genetic predisposition is a huge factor, etc.

But can we really expect that an 1800 calorie/day diet of sugar cubes is no more likely to cause insulin insensitivity than 1800 calories of non-sugary/starchy food?
