Glycemic Index
Overview of the Glycemic IndexThe glycemic index consists of a scale from 1 to 100, indicating the rate at which 50 grams of carbohydrate in a particular food is absorbed into the bloodstream as blood-sugar. Glucose itself is used as the main reference point and is rated 100.
What is the Glycemic Index?
The glycemic index, invented in 1981 by David Jenkins and Thomas Wolever of the University of Toronto, is a new system for classifying carbohydrate-containing foods, according to how fast they raise blood-glucose levels inside the body. In simple terms, a food with a higher glycemic value raises blood glucose faster and is less beneficial to blood-sugar control than a food which scores lower.
Glycemic Index Replaces Simple and Complex Carbs
The glycemic index method of classifying carbohydrates according to their effect on blood-glucose, replaces the older method of classifying carbohydrates according to their chemical structure of either "simple" or "complex" carbohydrates.
Uses of Glycemic Index - Diabetes and Weight Control
Although the glycemic index was invented originally to help diabetes patients manage their blood-sugar levels, dietitians and weight experts now use it as a tool to treat obesity, reduce cravings and appetite swings, and improve eating habits. Another important carbohydrate rating tool is the Glycemic Load which rates the glycemic value of food serving sizes.
GI Diets Better Than Low Carb Diets
According to clinical trials, GI diet programs provide an excellent dietary approach for people who want to reduce weight. By advocating the consumption of carbohydrate-rich foods with a low GI-value, and the avoidance of refined carbs, GI diet programs provide dieters with the best of all worlds - better blood glucose control and a highly nutritious eating plan. The health advantages of a low GI diet plan are one reason why it has superceded the low carb diet as the most popular weight loss plan.
High, Intermediate and Low Glycemic Index Foods
1) High Glycemic Index Foods (GI 70+), that cause a rapid rise in blood-glucose levels. (2) Intermediate Glycemic Index Foods (GI 55-69) causing a medium rise in
blood-glucose. (3) Low Glycemic Index Foods (GI 54 or less), causing a slower rise in
blood-sugar.
