Glycemic index & Glycemic load Flashcards
…. a ranking system for foods containing carbohydrates
glycemic index (GI)
glycemic index (GI) value show
How quickly each food increases blood glucose levels compared with eating a standard amount of glucose (50g)
Low GI
less than 55
Intermediate GI
55 - 70
High GI
greater than 70
lower the GI importance
More slowly digested, absorbed and metabolized and cause a lower and slower rise in blood glucose and , therefore usually , insulin levels
Low GI examples
most fruits and vegetables, milk, some wholegrain cereals and bread, pulses and basmati rice
Research shows ….. affect blood glucose levels
Amount and type of CHO
….. , in general, is stronger predictor of blood glucose response
Total amount of CHO in food
Which one has bigger effect on blood glucose ?
amount of carbs or GI
The amount of carbs
Pasta VS melon
Pasta has a lower GI than watermelon , but pasta has more carbs than watermelon
Pasta will have more of an impact on your blood glucose levels
The most important thing to do is get …
your portion size right
combines both the quality and quantity of carbohydrate in one ‘number’
Glycemic load or GL
The best way to predict blood glucose values of different types and amounts of food
Glycemic load or GL
Recommendations for using GI in your diet
At least 3 low GI foods throughout the day
