This is a function of the type and quantity of carbohydrate, as well as the method of preparation and the presence of other substances in the food, such as soluble fiber, fat, and protein. For example, your body absorbs glucose from whole fruit differently from extracted fruit juice due to the fiber content.
The glycemic index compares the rise in blood sugar level after eating a particular food to a reference food, often glucose. Glucose has a GI of The GI of fructose is 25 and sucrose, which is a blend of the previous two, has a GI of Most natural sweeteners are a combination of these three carbohydrates. Figure 1 shows the difference between a low GI and a high GI food in terms of effects on blood glucose levels over time. The glycemic load GL is a more accurate tool for assessing the impact of eating carbohydrates.
It gives a more complete picture than does glycemic index alone, because it accounts for the amount of carbohydrate in a serving. A GI value indicates only how rapidly a particular carbohydrate turns into sugar, whereas GL accounts for how much of that carbohydrate a person would typically eat. The carbohydrate in watermelon, for example, has a high GI. However, there is not a lot of sugar in a serving of watermelon, since most of it is fiber and water.
Foods that have a low GL almost always have a low GI. In contrast, foods with an intermediate or high GL can have a GI that ranges from very low to very high. Conversely, diets with high glycemic index or glycemic load are strongly associated with type 2 diabetes incidence. Creative Commons license. Veterans Crisis Line: Press 1. Complete Directory. Here you will find glycemic index and glycemic load for more than common foods. Glycemic Index is a type of numerical value that reflects the reduction or increase in your blood sugar due to food items, that is, by the value it is detected that by which food has increased rapidly in your blood sugar Or decreased.
Glycemic INDEX is a rating system for food items containing carbohydrate, by which food items you are eating, and how much glucose leaves. Low Glycemic Index leaves glucose slowly and continuously while the high glycemic index leaves glucose rapidly.
Glycemic index has a rating from 1 to , in which if the glycemic value comes 55 or less then it is placed in the category of low glycemic index i. These include potatoes, corn, cosmakus, white rice, and breakfast cereals such as mini-wheat and cream of wheat. High-Gi Foods Meaning of 70 or more Glycemic Index High GI foods include white bread, cake, most crackers, bagel, donuts, cookies, rice cakes, croissants and most packaged breakfast grains.
Low GI Foods : Green vegetables , most fruits, raw carrots, kidney beans, chickpeas, lentils and bran breakfast cereals. Medium GI : Sweet corn, bananas, raw pineapple, raisins, oat breakfast cereals, and multigrain, oat bran or rye bread. High GI : White rice, white bread and potatoes. Download PDF Now.
