Do you mean Diabetes Specialist Nurse?
I am Type 2 but my intake of any sort of grain as very low - some weeks I might get down to zero.
From time to time I use gluten for baking, but that is just a couple of times a year - it is the carbs I need to look out for.
As a rule I do not anything with over 10% carbs, makes it a lot easier to keep my numbers normal.
Grains were not really part of the Human diet until a few thousand years ago, not even the blink of an eye in terms of our evolution.
