There was a story here about the Irish tax authority classifying Subway bread as a sweet, not as bread, due to the high sugar content. I think that's an accurate description of a lot of american breads.

Usually when I buy bread in the bread isle i discard all that have added sugars. But it's been getting hard recently.
