NUTRITN 230 Lecture Notes - Lecture 9: Glycemic Load, Glycemic Index, Jelly Bean
Document Summary
Glucose delivered in blood to provide energy to cells. Glycemic response rate, magnitude and duration of the rise in blood glucose that occurs after a particular food or meal is consumed. Glycemic index blood glucose response of a given food with 50g cho, compared with a standard (typically 50g glucose or white bread) Serving size of food with 50g cho given. Blood glucose measured repeatedly over a 2 hour period. Blood glucose response compared to that of 50g glucose. Amount of fat and protein present in meal. Gi not based on amounts of carbohydrate in a typical portion of food (50g) Glycemic load assess glycemic response taking into account both the gi and amount of carbohydrate in a typical portion. Glycemic load = (gi x grams of cho in 1 serving) / 100. One medium peach (gi: 42, 11 g cho) Consume a variety of brightly colored fruits and vegetables. At least half your grains should be whole grains.
