1. Increased Antioxidant Power
Green tea contains potential antioxidants known as catechins and flavonoids. Antioxidants help fight disease by protecting the body's cells from damage by free radicals. Their function is to neutralize free radicals, which are formed when cells burn oxygen for energy. Laboratory tests found that tea produced greater antioxidant activity than 22 commonly consumed fruits and vegetables.
2. Research Continues to Study Green Tea and Cancer
Despite promising research in the laboratory regarding green tea and cancer, studies involving humans so far have been inconclusive. Laboratory studies, most done on mice. have analyzed catechins in green tea as powerful inhibitors of cancer growth. How does this occur? The antioxidants--named EGCG (epigallocatechin-3-gallate)--decrease tumor size, scavenge oxidants before cell injuries occur and inhibit tumor growth. In humans, research has been limited, some with unclear mechanisms and others with contradictory results.
3. Benefits of Green Tea
Why drink green tea anyway? Besides its antioxidant effect, it is rich in important nutrients, manganese, fluoride, potassium and zinc. Fluoride in tea can prevent against tooth decay and dental plaque. A cup provides about 80 mg of caffeine--specifically half the amount that's in coffee and, if processed correctly, the decaf version contains the same beneficial flavonoids.
4. Amounts to Drink--How Much Is Enough?
Studies show significant differences in the recommended quantities of tea needed to obtain health benefits. Amounts range from 2 cups to 6 cups daily for prevention, while other proponents have mentioned up to 12 cups. Yet even 1 cup daily can increase your antioxidant levels. Serve it hot or cold--it's the same and depends on your preference. Choose freshly brewed tea over bottled as the latter contains less flavonoids.
5. Brew Green Tea--The Right Way
Tea experts suggest a science behind the perfect cup of green tea. A key factor is not to over-brew, resulting in a change of flavor. Bring water to a boil in a kettle. Once complete, let stand up to 3 minutes. Pour the boiled water over 1 tea bag--or 1 to 2 teaspoons of green tea per cup. Allow it to steep for up to 3 minutes and then remove the tea bag. Cool for 3 more minutes before serving. At last, relax and enjoy a sip of perfectly brewed green tea.
