The Glycemic Index ranks the food on how they affect the blood glucose level. The Glycemic Index measures how much the body glucose increase in two or three hours after eating. It is all about foods high in carbohydrates. The Glycemic index uses scale from 1 to 100, which indicates the rate at which 50 gm of carbohydrates in a particular food is absorbed into blood stream as blood- sugar. HOW LONG IT TAKES TO MEASURE GI:
Measuring the Glycemic index or GI rating of food is conducted under strict conditions, although methods can vary slightly. It is hard to generalize about which carbohydrates are high on GI list and which are low, because GI index is simply a measure of time. Carbohydrates that break down rapidly during digestion have highest Glycemic indices. Carbohydrates that break down slowly, releasing glucose gradually into blood stream, have a low Glycemic index. Now, how long it takes 50 gm of food's carbohydrates to turn in to blood sugar, regardless of serving size. To measure, for instance, of carb-to-sugar conversion time for whole apple doesn't tells how much carb is in one serving of food. Thus, the latest advancement in food science is to look at meals GI (Glycemic Load), which considers both GI of a food and amount of carbs in one serving of food. The higher a food's GL, the more it will cause the blood sugar to spike and less control over the energy levels. The meals with low GI (balanced dinner chicken, high-fiber vegetables), the food is digested more slowly. Then the blood sugar rises only incrementally and that slow digestion means that glucose is available as energy for hour and hour to burn blood sugar. For example, a 100gm slice serving of watermelon with GI of 72 and carbohydrates content of 5g makes the calculation 5* 0.72= 3.6 So that GL is 306. The GI of food varies from person to person and even in single individual from day to day depending on blood glucose levels and other factors. The GI of food varies depending on the kind of food, the length it was stored and how it was cooked. |
