There seems to be a misconception that quinoa is a grain, but it is actually a seed and what they call a pseudocereal. Like a grain, the numbers read high in carbs, but it is a complex carb with a low glycemic index. It's packed with enough essential amino acids and nutrients that will benefit diabetics, even with the high carb reading. Just everything in moderation.
In Cy's case, I feel that this makes for part of a great post work-out dinner. He has a tendency to go very hypoglycemic after meals after his workouts, so quinoa is a good balance.
Not only that, but the dish is pretty enough to serve for company as a side or appetizer. It's good for everyone!
