II. 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

III. Indications: Focus on lower Glycemic Index foods

  1. Obesity Management
  2. Diabetes Mellitus Management
  3. Coronary Artery Disease Management

    2. Bran muffins
    3. White bread
    4. Whole wheat bread

Ontology: Glycemic Index (C1136206)

Definition (CHV) a scale that ranks carbohydrate rich foods by how much they raise blood glucose levels
Definition (CHV) a scale that ranks carbohydrate rich foods by how much they raise blood glucose levels
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 (NCI_NCI-GLOSS) A measure of the increase in the level of blood glucose (a type of sugar) caused by eating a specific carbohydrate (food that contains sugar) compared with eating a standard amount of glucose. Foods with a high glycemic index release glucose quickly and cause a rapid rise in blood glucose. Foods with a low glycemic index release glucose slowly into the blood. A relationship between the glycemic index and recurrent colorectal cancer is being studied.
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.
