Glycemic index is just a bit weird in that it’s a measure using 100g of whatever food you’re eating. So even if something’s made with straight glucose, if there’s quite a few other macronutrients, water, etc. in the product then it’s not going to rate quite as high.
Same thing goes the other way around as well. Table sugar’s got a huge GI, but there’s no way you’d take in 100g all at once (I hope).
Try looking into Glycemic Load, it’s a bit more realistic. Plus if a food’s label straight up says that it’s made with a ton of simple sugars you really shouldn’t need a glycemic index score to tell you that it’s going to shoot your blood sugar up quite a bit.[/quote]
thank you for your reply. the serving size for the jam and the nutella was actually 20g as oppose to 100g. i dont think many people would smash in 100g of jam or nutella at a time (a typical jar is 200g). the GL was also low from a 20g serving. 4 for the nutella and 10 for the jam.
