My question wasn't the one you answered actually answered though. The article posted, if I understand it correctly, says that subtracting fiber from carbs to reach net carbs is rubbish. That higher carbs still cause blood sugar spikes even though they are fiber based carbs, and this is just a marketing based ploys by companies to promote their product to low-carbers. This is the concern I had, and wanted to know if any of the scientists here think this claim is valid.
Carbs, whether they come from sugar or fiber, are going to cause SOME kind of insulin reaction. Diabetics do not use Net carbs to calculate their insulin dosing, they use total carbs.
The difference is that simple sugars and starches cause a FAST insulin reaction while fiber causes a very slow, controlled reaction. Fast acting carbs are the reason we experience "sugar crash" or "carb crash" after eating them - insulin spikes up high to deal with the sudden flood to our system, which causes a sudden drop in blood glucose levels and hypoglycemic symptoms. THAT makes you hungry, fatigued, dizzy, irritable...all things that can lead you to eat MORE.
Fiber is slow-acting, and does not cause the dramatic insulin spike that fast acting carbs do. Your body doesn't have to "flood" your system to deal with a sudden onslaught of sugar.
I would however say that sugar alcohols are used by the food industry to market "low carb" foods that really aren't preventing that insulin spike after all. Many sugar alcohols have an effect on blood sugar levels very similar to fast acting carbs. Even the American Diabetes Association suggests that those following an advanced insulin protocol only subtract HALF the sugar alcohols from total carbs.
Quest bars reduce carbs primarily by using a plant fiber (Oligosaccharides), not sugar alcohols. I have never subtracted sugar alcohols from total carbs because of the similarities to fast carbs.
