Similar to other citrus fruits like grapefruits, lemons, and tangerines, oranges contain an abundant amount of immune-boosting vitamin C. They also have polyphenols and terpenes, which are antioxidants found abundantly in citrus fruits. These molecules can help block tumor growth while also enhancing the anti-cancer properties of other fruits and vegetables, increasing their concentration within the bloodstream.

While oranges are relatively high in natural sugars, they make an excellent dessert or healthy snack option when your blood sugar feels low, since their fructose is easily and quickly absorbed by the body. If you feel a cold coming on, oranges make a smart substitute for expensive, heavily marketed vitamin C supplements.
