Why does a bowl of cereal screw with your blood sugar when you are diabetic?

I have gestational diabetes. I’m doing fine with everything except breakfast. It’s rough. First they cut off my fruit supply and then it seems that everything remotely breakfast like is off limits—except eggs. And I’m not a huge egg fan.

I look at the carb exchanges for a serving of milk and a serving of a certain dry cereal—it fits what I’m allowed to have for breakfast. Yet if I eat cereal and milk, my blood sugar is through the roof.

I asked my dietitian what was up and she said “Oh all you pregnant ladies can’t handle your cereal. I don’t know why.”

That wasn’t quite the answer I was looking for. Anyone actually have a theory about why milk and cereal is so terrible?

The cereal in question is Special K by the way. It’s the lowest carb exchange I could find without actually being twigs.
