Not only that, but you also do realize that once you add other foods such as a fat source to a "high GI" meal like pure sugar, then that will slow down the digestion down greatly, and the "supposed" spike in blood sugar isn't going to happen since the absortion is slowed down..and you can pretty much compare the rate at that point to the absorption rate of oatmeal. When it comes down to it, unless you're only eating these high GI carbs in a completely fasted state, the whole concept of the gly***ic response comparison argument is gone.
Also, most people have a healthy insulin response (response to carbohydrates.) People have an appropriate amount of response to insulin (not having issues with high blood sugar and low blood sugar). These are the same people that don't have to worry about the gly***ic index even while in a fasted state because their body will take care of the gly***ic response. Most people don't even understand what the "spike means." The obvious answer to that is a dramatic increase in insulin, but that doesn't really happen since your body is so efficient in keeping your blood sugar in a good level range. If you have high or low blood pressure consistently, then you will die. If you ate gummy bears and your blood sugar spikes - if that was realistic, then you would have people dying from eating gummy bears, which just doesn't happen obviously. Remember, your body is extremely efficient in keeping your blood sugar in that "tight range." Also, keep in mind consuming these carbohydrates in a completely fasted state is unrealistic anyways unless you actually wait 48 hours before having this high GI meal.
What I find amusing is bodybuilders or health oriented people that obsess over the gly***ic index. These are the people who lift multiple times per week which improves insulin sensitivity, improves blood glucose tolerance, and most aren't obese either. This is the group that is the LEAST likely that won't have any issues in this department! If you think you have a problem, then you can have your fasted blood glucose tested (how much blood sugar is in your system in a fully fasted state). I know it's mind baffling you to accept this rather than from what you hear from Flex Magazine, but these are just what science has shown.
