  1. Physiology: Glycemic Index (GI)
    1. Rate of food digestion relative to glucose
      1. Compared to glucose or white bread as the control
    2. High glycemic food adverse effects
      1. Hyperglycemia may persist for 2 hours after meal
        1. Stimulates higher Insulin release
      2. Hypoglycemia results within 2 to 4 hours after meal
        1. Stimulates appetite
        2. Raises free fatty acid levels
    3. Glycemic load (GL)
      1. Corrects glycemic index for serving size
      2. Examples
        1. Scone GI is high at 92, but GL is low at 8
        2. Arborio rice GI is only 69, but GL is high at 36
  2. Indications: Focus on lower glycemic index foods
    1. Obesity Management
    2. Diabetes Mellitus Management
    3. Coronary Artery Disease Management
  3. High glycemic foods (index >60): Rapid energy source
    1. Beverage
      1. Carbonated soft drinks (non-diet)
      2. Maltodextrin, sugar solution (7.5%)
      3. Maltodextrin solution (20%)
      4. Sucrose solution (6%)
    2. Breads and grains
      1. Bagels
      2. Bran muffins
      3. White bread
      4. Whole wheat bread
      5. Corn flakes
      6. White short-grained rice or sweet rice (sticky rice)
      7. Doughnut
    3. Fruits
      1. Over-ripe bananas
      2. Raisins
      3. Watermelon
    4. Vegetables
      1. Carrots
      2. Baked potato
  4. Moderate glycemic foods (index 40-60)
    1. Beverage
      1. Unsweetened apple juice
      2. Orange juice
    2. Breads and grains
      1. Whole grain rye bread
      2. Oatmeal
      3. Pasta (e.g. spaghetti)
      4. Rice (lowest GI in long grain, brown, and Basmati)
      5. Muesli
    3. Fruits
      1. Grapes
      2. Oranges
      3. Under-ripe Bananas
      4. Dates
    4. Vegetables

      2. Yellow corn
      3. Peas
      4. Yams
    5. Legumes
      1. Baked beans
      2. Lentil soup
  5. Low glycemic foods (index <40): Constant energy source
    1. Fruits
      1. Apples
      2. Cherries
      3. Figs
      4. Ripe banana

Glycemic Index (C1136206)

Definition (NCI)A ranking of the relationship between various foods and glucose blood serum levels. The carbohydrate composition of the food directly effects the concentration of glucose in the blood. 2005
Definition (MSH)A numerical system of measuring the rate of BLOOD GLUCOSE generation by a particular food item as compared to a reference item, such as glucose = 100. Foods with higher glycemic index numbers create greater blood sugar swings. These numbers do not correspond to calories or amounts of food intake but rather, depend on the rates of digestion and absorption of these food items.
