I've discussed this very issue with several endos and nurse practitioners and there is also plenty of research that concludes it's not correct to make that claim.

Well, first i would say something that no one ever talks about. Doctors do not study nutrition. At all. Nurses... even less so.
With regard to blood sugar rising in relation to different foods, that can purely be psychological among other things. Just as if you were wearing a heart rate monitor, you were resting and i said "ok, we're going to run sprints in 10-9-8...", you're heart rate begins to rise before any work is done.
You have an enzyme in your saliva which detects carbs as well and it plays a role in your body predicting the energy value of the food you're consuming. This was discovered with cyclists where cyclists were given a drink which which they were told had carbs, though nothing could be tasted. Those who received actual glucose reliably increased their output, those who did not, did not increase their output.
You're brain can also influence your body's response simply by your perception and expectations of what you're ingesting (with or without conscious awareness).
It's not just a straight equation of "carb in vs blood glucose levels" or "this type vs that type". there is a LOT of individuality with carb sensitivity and an array of factors which determine how and to what extent your body will respond.
