How you rank fruit depends upon the reason you're eating the fruit and your individual tastes. The four most valuable nutrients in fruits are fiber, vitamin C, carotenoids (e.g. beta carotene), and phytonutrients (health-building substances). Here are our rankings - an overall "Top Ten Fruits" list and our top choices for fiber and vitamin C. Our top ten ranking of fruits is based upon their content of these nutrients: vitamin C, fiber, carotenoids, calcium, and folic acid. Availability, safety, and versatility also influenced these choices.
