Glycemic Index and Glycemic Load: Sports Bars
Friday, August 20, 2004 1:10 am Email this article
Below is a table with the glycemic index and glycemic loads of sports bars.
High glycemic index foods increase calorie intake by 50 to 80 percent when compared to medium- and low-glycemic index foods according to one study.
Low glycemic index foods reduce calorie intake and are associated with lower body weights.
Some researchers believe that low-carbohydrate diets work because they are low glycemic index and low glycemic load foods.
Glycemic index is how quickly a given amount of food raises blood sugar levels relative to pure glucose (blood sugar).
Glycemic load is a ranking of how much a standard serving of food raises your blood sugar. Glycemic load is calculated by multiplying the amount of carbohydrate in a food by the glycemic index and dividing by 100. Glycemic load of a food is a better tool than the glycemic index value of a food when evaluating the foods you eat.
A more complete description of glycemic index and glycemic load can be found here.
