Question

At Kate's next appointment, Paula showed Kate how to use a glucose meter. She instructed Kate to measure her blood glucose level twice a day before and after breakfast and dinner. Paula explains to Kate that her pre-meal blood glucose level should be 110 mg/dL or less, and if it increases by more than 50 mg/dL, she needs to lower the amount of carbohydrates she consumes. Kate and Paula proceed to plan several meals. Because a meal should contain about 45 to 60 g of carbohydrates, they combined fruits and vegetables that have high and low levels of carbohydrates in the same meal to stay within the recommended range. Kate and Paula also discuss the fact that complex carbohydrates in the body take longer to break down into glucose and, therefore, raise the blood sugar level more gradually. Kate increased her exercise to walking 30 minutes twice a day. She began to change her diet by eating 6 small meals a day consisting of more fruits and vegetables without starch such as green beans and broccoli, 1/4 cup of whole grains, and 1/4 cup of chicken or fish. Kate also decreased the amounts of breads and pasta because she knew carbohydrates would raise her blood sugar. After three months, Kate reported that she had lost 10 lb and that her blood glucose had dropped to 146 mg/dL. Her blurry vision had improved and need to urinate had decreased.

Answer 1

Part B : total kilocalories = 2.0 x 10² kcal

Explanation

Total mass of carbohydrates = (mass of carbohydrate from orange juice) + (mass of carbohydrate from slice of wheat toast) + (mass of carbohydrate from apple) + (mass of carbohydrate from coffee)

Total mass of carbohydrates = (23 g) + (12 g) * (15 g) + (0 g)

Total mass of carbohydrates = 50 g

total kilocalories from carbohydrates = (Total mass of carbohydrates) * (energy value of carbohydrate)

total kilocalories from carbohydrates = (50 g) * (4 kcal/g)

total kilocalories from carbohydrates = 200 kcal
