A nurse is providing teaching to the caregivers of a preschooler who has a new diagnosis of celiac disease. Which of the following foods should the nurse recommend?

A. Grilled hot dog with French fries: Hot dogs may contain fillers with gluten, and cross-contamination in fries is common if shared fryers are used, making this choice unsafe. B. Oatmeal cookie with raisins: Unless the oats are certified gluten-free, they may be contaminated with gluten during processing, posing a risk for children with celiac disease. C. Baked sweet potato with cinnamon: Sweet potatoes are naturally gluten-free, and cinnamon is safe as well. This option provides a nutritious and safe food for a child with celiac disease. D. Hazelnut butter on wheat toast: Wheat toast contains gluten and should be strictly avoided in individuals with celiac disease, even if the topping is gluten-free.
