Tea is the most commonly consumed beverage in the world after water. Whether it is black, green or red (oolong) tea, they all contain polyphenols which give tea its antioxidant properties. Antioxidants may help protect our body from free radical damage. Indeed, tea ranks as high as or higher than many fruits and vegetables in the ORAC score, a score which measures antioxidant potential of plant-based foods.
Benefits of Tea
Numerous studies have demonstrated the anti-cancer properties of polyphenols. Some studies indeed suggested that tea's polyphenols may reduce risk of gastric, esophageal and skin cancers if one consumes 4 to 6 cups daily. Other laboratory studies have found that polyphenols help prevent blood clotting and lower cholesterol levels. A recent study published in December 2005 showed that just 2 cups of tea may lower the risk of ovarian cancer by 46 percent in women.
The more processing tea leaves undergo, the darker they will turn. Green tea is the least processed tea. They are simply steamed quickly. Black and red teas are partially dried, crushed and fermented. Regardless of the processing method, all teas contain polyphenols.
