[QUOTE=c6h6o3]There's some kind of synergy there between this particular combination of ingredients which causes it to raise blood sugar far in excess of what one would compute based solely on the sum of the parts.

If my blood sugar is 85 before I eat even one piece of thin crust pizza, and I don't eat the rim, just the thin flat part, my bg will read at least 145 within 15 minutes. And that's just for one piece. I shudder to think what my blood sugar must have been after eating an entire pie, which I used to do quite regularly.

Actually, it does add up to the sum of the parts:

BG 145 minus BG 85 = 60 point rise. Since each gram of carb raises BG's by 5 points, 60/5 = 12 grams of carbs.

The crust and pizza sauce (tomato sauce, SUGAR, and spices) can easily have 12 grams of carbs.

Most people forget about all the SUGAR in pizza sauce, because the acidity masks the sweetness.
