1 Gary Scheiner MS, CDE Owner & Clinical Director Integrated Diabetes Services LLC (877) Use of Glycemic Index In Diabetes Management


3 Carbohydrate……. rapid digestion, total absorption/conversion to glucose (100%) Sugar Alcohols…. moderate digestion, partial absorption as glucose (50%) Protein…………….. slow digestion, partial conversion to glucose* (~40%) Fat…………………… slow digestion, little conversion to glucose** (0%) Timed Effect on Blood Sugar Levels * In absence of dietary carbs ** may cause insulin resistance in large qty

4 MEET THE CARBS! Fruit Fruit Juice Candy Regular Soda Punch Wine Muffins Milk Ice Cream Yogurt Sport Drinks Table Sugar Chocolate Cookies & Cakes Pies & Pastries Raisins/Dried Fruit Syrup Jelly

5 MEET THE CARBS! Potatoes Rice Noodles/Pasta Cereal Oatmeal Bread Tortillas Pancakes Waffles Crackers Bagels Pizza Beans Corn Pretzels Chips Popcorn Beer

6 The fate of dietary carbohydrates Simple Carbohydrates (sugars) Complex Carbohydrates (starches) Blood Glucose

7 Does the Type of Carbohydrate Matter? Glycemic Index All carbs (except fiber) convert to blood glucose eventuallyAll carbs (except fiber) convert to blood glucose eventually G.I. Reflects the magnitude of blood glucose rise in the first 2 hoursG.I. Reflects the magnitude of blood glucose rise in the first 2 hours G.I. Number is % of rise relative to pure glucose (in dextrose form)G.I. Number is % of rise relative to pure glucose (in dextrose form)

8 Glycemic Index (contd.) Example: Spaghetti GI = 37 37% of spaghettis carbs turn into blood glucose in the first 2 hours. The rest will convert to blood glucose over the next several hours.

11 What About MIXED Meals? Tends toward G.I. of primary food in meal (i.e. bread in sandwich) Eating low-g.i. food first lowers G.I. of entire meal

12 a G.I. Is NOT An Exact Science! V a b L $ Food combinations Quantity being consumed Time since last meal Recent & planned physical activity Individual food sensitivities The winner in the 3 rd race at Belmont

13 G.I. Gereralization Slow StuffAverage StuffFast Stuff Pasta Legumes Salad Veggies Dairy Chocolate Fruit Juice Pizza Soup Cake Breads/Crackers Salty Snacks Potatoes Rice Cereals Sugary Candies

14 If All Carbs Turn Into Glucose Eventually, Why Is Glyemic Index Important?

15 1. Satiety Low G.I. = Slower Gastric Emptying Leads to Less Consumption, Smaller Portions Less Tendency to Graze

16 Low Glylcemic-Index Foods Are More Satisfying! Jackie Scheiner Age 1

17 2. Mealtime Insulin Timing Goal is to match insulin action to foods effects, prevent high & low BG –High G.I.: min prior –Moderate G.I.: 0-15 min prior –Low G.I.: 0-15min after

18 Normal Pump Bolus with Low-G.I. Meal: Insulin peaks too early (hypoglycemia) Insulin dissipates too soon (hyperglycemia)

19 Square/Extended/Long Bolus Entire bolus is delivered gradually over 30min – 8 hrs 1 -2 hours is common Insulin Pump Options

20 Dual/Combo/Combination Bolus Part of bolus delivered up-front, remainder over time 30% Up-Front is common, remainder over 2 hrs Insulin Pump Options

21 3. Reducing Post-Meal Spikes Glucose variability is associated with increased complication risk, emotional distress, and diminished physical & intellectural performance Injected/infused rapid insulin is much slower than insulin produced by the pancreas The amylin hormone is lacking or deficient

22 3. Reducing Post-Meal Spikes LOW G.I. FOODS PRODUCE FLATTER BGs! Diabetes Self-Management, August, 2006

23 Factors that lower G.I. Fiber Fat Temperature Solid (vs. liquid) Acidity Non-Processed Type of carb

29 4. Treating Hypoglyemia High-GI foods convert to glucose rapidly (faster recovery) Lower-GI foods take longer to work, may lead to over-treatment and significant post- treatment hyperglycemia

30 Hypoglycemia Treatment High-GI Foods Dry Cereal Pretzels Graham Crackers Vanilla Wafers Jelly Beans Gatorade Regular (non-diet) Soda

31 Hypoglycemia Treatment DEXTROSE Rules! (GI=100) Dex Products Glucose Tablets Glucose Gel Liquid Blasts Dextrose-Sweetened Candies Sweet Tarts Smarties Spree Air Heads Nerds Runts
