In common UK parlance carbohydrates don't include sugars although chemically speaking they should. I think metabolically speaking there is a useful distinction to be made, in fact people are making it here. In dietary context schools have categorised potatoes, rice, pasta, even bread as sources of "carbohydrates" and sweets as sugar sources.
