There's a world beyond the same old apple and grape juice you've been buying for your family forever. Why not break out of your beverage rut and experiment with some of the more exotic flavors out there? Besides being tasty, many unusual juices are said to offer protection from disease. So mix up your morning (or afternoon!) routine and give these a whirl:

Pomegranate juice. This powerhouse of a drink contains antioxidants—especially polyphenols—at a much higher level than more conventional fruit juices, which helps keep your heart healthy. In fact, according to experts at the Mayo Clinic, preliminary studies indicate that pomegranate juice may lower cholesterol levels. The only caveat? The juice may affect how certain prescription drugs are metabolized by the body, and may also cause dangerously low blood pressure if taken with certain blood-pressure medications. If you plan to make this part of your juicing regimen, check in with your doctor.

Mangosteen juice. The mangosteen, a tropical fruit grown in Southeast Asia, is brimming with antioxidants, especially xanthones. The fruit is often pureed and sold as a drink, although it's not widely commercially available. Mangosteen proponents usually buy their products at health food stores, online, or through a distributor. Although untested in humans, mangosteen extract showed some promise in inhibiting cancer-cell growth in the bowels of rats. Devotees also claim mangosteen juice cures migraines, improves flexibility, and offers many other health benefits.

Goji juice. Like other juices, goji is rich in antioxidants and vitamins. But while a few small studies hint at a possible anti-cancer benefit, there isn't strong evidence to support this claim. Goji juice also may interact with certain diabetes medications. The verdict? If you like the taste and are sure it won't clash with your medicines, drink it!

"Green" juice. This is a blend of fruit and vegetable juices popularized by cardiac surgeon Mehmet Oz, M.D., on Oprah. You can find various green juices at health-food stores, or you can make your own in a juicer or blender. The juice typically contains spinach, apple, parsley, ginger, cucumber, celery and lemon; experiment to see which amounts you like, and feel free to add a little sweetener if you're not used to the taste. It's chock full of antioxidants, which help prevent cell damage, and also contains a hefty dose of fiber to keep your intestines working smoothly.
