Question: 61
What are some advantages of using carbohydrate counting instead of food
exchanges when following a diabetic diet plan?
A. Carbohydrate counting permits greater flexibility in food choices.
B. Individuals who count carbohydrates can save up all of their allotted
carbohydrate for one meal.
C. There are more “free food” choices when counting carbohydrates.
D. Carbohydrate counting emphasizes high fiber foods.
Answer: A
An advantage of using carbohydrate counting instead of food exchanges when
following a diabetic diet plan is that carbohydrate counting permits greater
flexibility in food choices. When using carbohydrate counting, 15 grams of
carbohydrate from bread, fruit, or milk all serve as one carbohydrate serving, in
contrast to the exchange system in which foods from different exchange groups
contain varying amounts of carbohydrate. Use of carbohydrate counting still
requires equal distribution of carbohydrate over meals and snacks, and attention
to the amounts of “free foods” consumed.
