I'd say you need to find out what works best for her

There's no magic diet unfortunately, but there are tools we can use to help control.
I don't know how old your daughter is, but most Type 1s find bolusing more in advance stops the spike. As an example, I eat a large bowl of cereal for breakfast (45g carbs). If I bolus right before eating (with Humalog) I can spike to 11 but if I bolus 30 mins in advance, my spike is in the 6s.
If I eat more than around 100-120g carbs per meal, I find control harder as the carbs seem to become less predictable in large amounts.
With experimentation, you'll find what works best for your daughter. Keeping wriitten records of meals helped me a lot. It takes time but it's worth it as it simplifies things in the future, knowing what to do for each meal.
