THE GLYCEMIC INDEX
READING: Read page 38 of the text on Glycemic Index
BOARD NOTES: We know that all carbohydrates function as relatively quick energy sources. However, simple carbohydrates cause bursts of energy much more quickly than complex carbohydrates, because of the quicker rate at which they are digested and absorbed.
The glycemic index (GI) rates carbohydrates on how quickly they are digested, absorbed and metabolised and raise the glucose level in the blood, over a two hour period.
Carbohydrates are given a score out of 100; the lower the score the lower the glycemic index. The foods you consume should have a low GI for sustained energy release. Carbohydrates that are rapidly digested, absorbed or metabolised, such as white bread, result in a rapid increase in blood glucose levels and have a high glycemic index of 70 or above.
ACTIVITY: Answer Question 1 & 2 on page 9 of your workbooklet in relation to the below graph.
