Eat at least five servings of fruits and vegetables. Select a variety, including sweet potatoes, apples, berries, apricots, peaches, pears, oranges, prunes, corn, peas, carrots, tomatoes, spinach, broccoli and cauliflower. And opt for the whole produce over juice as much as possible; a glass of orange juice, for instance, provides 0.1 grams of fiber, while eating an orange gives you 2.9 grams.
