Glucose metabolism Flashcards
What is a high and low Glycemic Load?
(GL)
High GL > 20
< 10 or below is considered low
How do you calculate net carbs?
Total carbs minus fiber
Formula to calculate Glycemic Load (GL)
GL = (GI × Net Carbs) ÷ 100
What is considered
High
Medium
Low
Glycemic Index
< 55 Low
> 70 High
55–69 Medium
Can the same foods can have a very different GI and GL depending on how they are prepared?
Give an example of a sweet potato
(boiled vs baked)
A boiled sweet potato has a low GI of 44 and a medium GL of 11
But if baked for 45 minutes, the same sweet potato has a GI of 94 and a GL of 42, both extremely high.
Baking has essentially turned the sweet potato into candy!
Does microwaving or baking raise GI and GL?
Microwaving AND baking often raises GI and GL.
That’s because much of the carbohydrate content of the food has been converted into glucose.
Does toasting bread increase its GI?
But what does it generate that is not good?
Opposite!
it often lowers the glycemic index
