When it comes to fiber, "people think that only grains can provide fiber and underestimate the value of fruits and vegetables," says nutritional scientist Judith Marlett, Ph.D., R.D., of the University of Wisconsin in Madison. She analyzed 325 common foods for their fiber content and found some surprises. For instance, ounce for ounce, stringy celery packs only half the fiber of an avocado.
