BBC News | HEALTH | Tea 'could help prevent cancer' (#)
„Tea contains antioxidants - polyphenols called catechins - that have been shown to be as powerful as the well-established antioxidants vitamins C and E at protecting proteins and DNA from oxidative damage. Green tea contains the most catechins, followed by oolong and black teas. Other studies have shown catechins can halt tumour cell growth and protect healthy cells from damage. Lower risk The team from the Keck School of Medicine of the University of Southern California, Rutgers University and Shanghai Cancer Institute began their research in 1986.“

Tea & Coffee 08/04 - The Latest Finds on Tea & Health
„Antioxidants are compounds that help clean harmful compounds from the blood. Tea contains several different types of antioxidants in the polyphenol family, including catechins, flavonoids, tannins and theraflavins. Flavonoids comprise an important sub-group of the polypheonols and green tea leaves contain high levels of flavonoid compounds, among them catechins (flavinols), and a related flavonoid, flavonis, is found in both green (unfermnented) and black (fermented) tea leaves. These and similar antioxidants are found in fruit and vegetables, but one or two cups of tea provides a similar “radical scavenging environment” as five portions of fruit or vegetables.“

„The first two are obtained through food, the others are produced by the body, but these levels decline as we age, so we need to supplement. Packer describes the benefits and actions of these special antioxidants and also recommends flavonoids such as ginkgo biloba and pycnogenol (made from the bark of pine trees), a number of carotenoids, selenium, and a variety of foods high in antioxidants. He spells out exactly what supplements you need and how much, with special modifications for smokers, diabetics, menopausal women, athletes, and people at high risk of cancer or cardiovascular disease. The book is not easy reading: lots of scientific explanations and study descriptions.“

„There is convincing evidence that oxidative damage is believed to be a major contributor to ageing and to degenerative diseases of ageing, such as cardiovascular disease, certain forms of cancer, decline of the immune system, brain dysfunction and cataracts. Antioxidants can be of great benefit in improving quality of life by preventing or postponing the onset of degenerative aging diseases. Protection against damaging free radicals can be enhanced by intakes of dietary antioxidants and coffee has been shown to be a significant source. This is further evidence that coffee drinking in moderation, 4-5 cups per day, is perfectly safe for the general population and may confer health benefits.“

Caffeine and Skin Cancer (INeedCoffee.com)
„At the time, the hypothesis presented was that caffeine was slowing down DNA repair after the damage produced by UV irradiation and, by slowing it down, was allowing the repair to be more precise, avoiding the mutations that lead to cancer. Caffeine has also been found to be an effective antioxidant, scavenging OH radicals, thus producing another mechanism for its anticancer properties.“
