A lot of white bread has actual sugar or high-fructose corn syrup in it as an ingredient. How much of that is to start the yeast and how much is for taste varies by brand. Whole-grain/white can be misleading as far a sugar goes. I've had whole-grain brands that were so sweet that I couldn't stand to use them for sandwiches.
