Addicted to coffee? In love with chocolate? That's good. Caffeinated foods, including coffee, chocolate, and tea, have high levels of polyphenols, dubbed "super" antioxidants for their ability to fight everything from cancer to depression. A Harvard University study even found that drinking five cups of coffee daily cuts the risk of developing diabetes in half. That much coffee could give you the jitters, though, so most experts recommend limiting intake to two cups a day, or switching to decaf. Whether you prefer tea or coffee, studies seem to suggest that decaf versions contain just as many antioxidants as the regular stuff. And, of course, dark chocolate is better than sugary milk chocolate or white; check out our organic chocolate taste test results for the best organic, Fair Trade brands.
