Fructose is poison.Glucose is awesome.They metabolize very differently in the body.http://www.youtube.com/watch?v=dBnniua6-oM&ob=av3e Pastries are mostly wheat. (In Norway anyways... Don't know about in the US, they might be made from pulverized baby skulls and radioactive waste over there for all I know)So pastries are mostly glucose. It's only the topping that contains sugar usually.
