Depending on the variety, salad dressing may be rich in multiple disaccharides. Creamy dressings are high in both lactose and sucrose, while vinegarettes are generally not a source of lactose but are high in sucrose. This of course, only applies to salad dressings that are not low calorie or sugar-free. Use these products only in moderation, though; too much added sugar in salad dressing is not good for you.
