Recipie advice needed

After managing my daughter's type 1 for 1 1/2 years I realized we will have to start making some changes to her diet. I want to cut back on her carbs. She has been a carb addict since her diagnosis. I want to try having a lot more whole grain foods in her diet and try some whole grain breads, rice and pasta. 

Do whole grains really help prevent glucose spikes in your experience? 

WHat are your favorite whole grain recipes? 

I want to try whole wheat pizza dough and cupcakes.
