As I understand it, eating them raw also means your body is slower to process all the carbs as it has more work to do, so if that's the case, you would see lower, slower spikes.
I like to eat a number of my vegetables raw, but it definitely depends on what other food I'm going to eat with them. However I am also quite careful about the type and quantity of vegetables I eat, and try to keep as low carb as possible while eating a good variety. And I eat them from choice rather than necessity, as I agree with the other posters,that carbs are not really an essential part of our diet.
