Step-by-step explanation:
The student is inquiring about the appropriate portion size for grain products, specifically the amount of whole grain bread that constitutes one serving. Considering that a single slice of whole grain bread typically contains about 15 grams of carbohydrates, the CFG (Canada's Food Guide) suggests that a serving of grain products should weigh approximately 50g.
Therefore, the correct answer to the student's question is: B) 2 slices, 50g. This aligns with the nutrition information about grain servings and whole grains as presented in dietary guidelines.
Maintaining a balanced diet involves consuming a variety of foods including whole grain breads and ensuring half of your daily grain intake is from whole grains.
