17 Superfoods That Fight Disease
Why they're super: Just one medium orange (think tennis ball) supplies all your daily vitamin C, which is a dynamite immunity booster and cancer fighter. And consuming vitamin C is best done in its natural form: Italian researchers also found that test subjects had greater antioxidant protection after drinking orange juice versus vitamin C–fortified water. Plus, this sweet and tangy fruit is a good source of fiber, potassium, calcium, folate, and other B vitamins.
How to enjoy them: The tangy taste of oranges makes a great combination with other strong flavors, such as ginger and honey. Put them on salads, or use them in marinades and sauces for meats.
