multiply grams of total carbohydrates on the label by the number of servings eaten Food Labels • Example: You just ate 10 crackers from the previous label • There are 2 crackers/serving • How many servings did you eat? –5 • How many total carbohydrates did you consume? – 10 g/serving x 5 servings=50 g Tools for Carbohydrate Counting Nutrition Labels Measuring Tools Carbohydrate Counting Hand Guide Thumb= 1 oz Fist=8 fl oz or 1 C Palm=3 oz Handful=½ C C=cup, fl oz=fluid ounce, oz=ounce, tsp=teaspoon Thumb tip=1 tsp Sample Menu #1 How many carbohydrates are in this meal? Six chicken nuggets=? Two packets of ketchup=? One small banana=? 8 fl oz of 2% milk=? Small bag of potato chips=? 8 fl oz of iced tea (unsweetened)=? Sample Menu #1 Answers How many carbohydrates are in this meal? Six chicken nuggets=15 g Two packets of ketchup=6 g One small banana=15 g 8 fl oz of 2% milk=12 g Small bag of potato chips=15 g 8 fl oz of iced tea (unsweetened)=0 g TOTAL=63 g Sample Menu #2 Breakfast Two slices of toast, 4 fl oz of juice, 6 fl oz of milk Snack 1 Three graham crackers, one slice of cheese Lunch Hot dog on bun, 15 French fries, 4 fl oz of milk, two ketchup packets Snack 2 One slice of bread, one slice of cheese Dinner 1 C macaroni and cheese, one small piece of fruit Snack 3 Four graham crackers, 1 Tbsp peanut butter Sample Menu #2 Answers Breakfast=50 g Snack 1=15 g Lunch=72 g Snack 2=15 g Dinner=60 g Snack 3=232 g Insulin-to-Carbohydrate Ratio • Insulin-to-carbohydrate ratio: The units of insulin needed to "cover" a specified number of carbohydrate grams • An important tool for intensive diabetes management • Divide the total grams of carbohydrate consumed by the carbohydrate-to-insulin ratio Insulin-to-Carbohydrate Ratio (cont’d) • To improve blood glucose control for people using intensive diabetes management, match the amount of insulin with carbohydrate intake • Understanding carbohydrate counting is required: – To assure the administration of the appropriate insulin-to-carbohydrate ratio at mealtimes in hospitalized patients – For glycemic control – For the prevention of hypoglycemia and/or hyperglycemia Insulin-to-Carbohydrate Ratio (cont’d) • Example: A child is to consume a 60-g carbohydrate diet • The child’s premeal blood glucose is within the normal range • The child’s insulin-to-carbohydrate ratio is 1:20 • For every 20 g of carbohydrate eating, 1 unit of fast-acting insulin (NovoLog®) is required Insulin-to-Carbohydrate Ratio Answers • 60 g total carbohydrate/20 insulin-tocarbohydrate ratio=3 • Therefore, 3 units of fast-acting insulin (NovoLog) are required for this meal References • American Diabetes Association.
