Best Place to Buy: Farmer’s market

Benefits: High vitamin C content

Like other citrus fruits–grapefruits, lemons, and tangerines–oranges have an abundant source of vitamin C. They also contain polyphenols and terpenes, the main molecules of citrus fruits, which both have the capacity to block the growth of tumors and potentiate the anti-cancer properties of other fruits and vegetables, increasing their concentration in the blood.

While they are high in natural sugars, they make an excellent dessert or healthy snack when you’re feeling low in blood sugar, as their fructose is easily absorbed by the body. If you feel a cold coming on, it’s a smart idea to reach for an orange instead of one of those expensive, heavily marketed vitamin C cocktails.
