Example of the Glycemic Index (GI) being useless
In several of my newsletters in the past, I've given examples of how choosing your foods based on the glycemic index can be misleading and useless in many cases.
Case in point...
Watermelon has one of the highest measured GI's of all foods (much higher than even cake and ice cream). However, a normal serving of cake and ice cream may give you a whopping 700 or 800 calories, whereas a typical serving of watermelon may give you 50 or 60 calories max!
Trust me... watermelon isn't making anyone fat!
The lesson... GI is almost useless when you're not considering "Glycemic Load", which also factors in the quantity of carbohydrates ingested in a typical serving.
