Researchers from the University of California, Los Angeles have ranked 10 beverages according to their antioxidant levels.Currently, claims of superior antioxidant activity on beverages can be misleading, as the testing is usually based on a limited spectrum of antioxidant activities.
To get to the bottom of which beverages are best, they used four tests of antioxidant potency, a test of antioxidant functionality, and an evaluation of the total polyphenol content of polyphenol-rich beverages in the marketplace. Here is how the rankings turned out:
1. Pomegranate juice
2. Red wine
3. Concord grape juice
4. Blueberry juice
5. Black cherry juice
6. Açaí juice
7. Cranberry juice
8. Orange juice
9. Tea
10. Apple juice
