Pomegranate has quickly become one of the most talked about super foods in the past two years. Pomegranate fruits contain polyphenols, tannins and anthocyanins, which are all beneficial antioxidants. On the other hand, pomegranate juice contains high levels of antioxidants - higher than most other fruit juices, red wine or tea. Preliminary evidence suggested that drinking concentrated pomegranate juice may reduce cholesterol. It was further suggested that drinking a glass of pomegranate juice a day for one year reduced blood pressure (particularly systolic pressure) and slowed down low density lipoprotein or LDL cholesterol (the bad cholesterol) oxidation.

Many studies so far were small, thus more research is needed to fully evaluate the possible health benefits of pomegranate. Pomegranate juice is generally safe to drink. Most studies have administered a daily helping of 1.5 ounces (45 milliliters) of pomegranate juice with no significant side effects.
