I’ll find out during my next appointment, thanks!
I would not assume that a doctor has in depth knowledge regarding the impact of food and nutrition on diabetics. Most MDs think in simplistic terms of 'reduce sugar and carbs'. Their primary focus is to prescribe medicines. Many look down their nose down on nutritionists and studies as the one I cited earlier. Many would be ignorant of the "whole-grain" response to glucose as compared to "refined-grain" carbs.
