How a Glycemic Index Value is Calculated
The glycemic effect of foods depends on a number of factors such as the type of starch, fat content of the food and increased acidity of the meal – adding vinegar, cheese, or peanut butter, for example, will lower the GI. A low GI food will release energy slowly and steadily and is appropriate for dieters and endurance athletes. A high GI food will provide a rapid rise in blood sugar levels and is suitable for post-endurance exercise energy recovery.
