Much has been written and said about the amazing health benefits of tea. So much in fact, that it’s often difficult to separate fact from fiction. What are the scientifically recognized benefits of tea? The following is a brief synopsis of the latest findings.
If you are the type to fret over the appearance of wrinkles, age spots and other signs of growing old, oolong tea may be the answer to your worries. In a recent experiment carried out jointly by researchers from the US, Taiwan and Japan, mice which were fed tea displayed fewer signs of aging than mice that were fed water.

The wonder cup just got even more wonderful. Green tea, rich in antioxidant treasures that protect against heart disease and cancer, now shows promise as an allergy fighter. In laboratory tests, Japanese researchers have found that the antioxidants in green tea, block the biochemical process involved in producing an allergic response. Green tea may be useful against a wide range of sneeze-starting allergens, including pollen, pet dander, and dust. Prevention, April 2003
Green tea catechins are chondroprotective and consumption of green tea may be prophylactic for arthritis and may benefit the arthritis patient by reducing inflammation and slowing cartilage breakdown. The Journal of Nutrition, Mar 2002

Tea flavonoids may be bone builders. A report in this week’s Archives of Internal Medicine looked at about 500 Chinese men and women who regularly drank black, green, or oolong tea for more than 10 years. Compared with nonhabitual tea drinkers, tea regulars had higher bone mineral densities, even after exercise and calcium-which strengthen bones-were taken into account.

« Tea is one of the single best cancer fighters you can put in your body, » according to Mitchell Gaynor, MD, director of medical oncology at the world-renowned Strong Cancer Prevention Center in New York City and co-author of Dr. Gaynor’s Cancer Prevention Program. The latest tea discovery? Strong evidence that both green and black tea can fight cancer-at least in the test tube-though green tea holds a slight edge. In a new study, both teas kept healthy cells from turning malignant after exposure to cancer-causing compounds. Prevention, May 2000
People who drink about 4 cups of green tea a day seem to get less cancer. Now we may know why. In recent test-tube studies, a compound called EGCG, a powerful antioxidant in tea, inhibited an enzyme that cancer cells need in order to grow. The cancer cells that couldn’t grow big enough to divide self-destructed. It would take about 4 cups of green tea a day to get the blood levels of EGCG that inhibited cancer in the study. Black tea also contains EGCG, but at much lower concentrations. Prevention, Aug 1999
Studies indicate that chemicals known as polyphenols in tea assistance forbid cancer. Researchers compared the diets of 900 folk with esophageal cancer with those of 1,500 who did not get the cancer. The folk with cancer drank significantly less greenish Organic Tea .The much greenish tea, the little cancer. In addition, greenish tea was added to the drunkenness water of empirical mice and so exposed them to chemicals known to induce a kind of tumors in rodents. The mice who drank the green-tea-laced water developed substantially less tumors than the mice who drank simple water.
These studies prompted headlines proclaiming « Green Tea Prevents Cancer. » Unfortunately, few Americans drink greenish tea outside of Asian restaurants; most Americans drink dark tea. It has the related consequence overly.
Tea can lower ‘bad’ cholesterol levels. Researchers at the Beltsville Human Nutrition Research Center in Beltsville, Maryland, asked test subjects to eat low-fat, low-calorie prepared meals and drink five cups of caffeinated tea or caffeinated and non-caffeinated placebos that mimicked the look of tea. Levels of low-density lipoprotein (LDL) cholesterol dropped 10 percent among the test subjects who drank tea. Vegetarian Times, Jan 2003
Drinking black tea may lower the risk of heart disease because it prevents blood from clumping and forming clots. In a recent study, researchers found that while drinking black tea, the participants had lower levels of the blood protein associated with coagulation. Better Nutrition, Jan 2002
Better to be deprived of food for three days than tea for one, says a Chinese proverb. Research is showing it may just be true. Dr. Kenneth Mukamal of Boston’s Beth Israel Deaconess Medical Center reported that out of 1,900 heart-attack patients, those who drank two or more cups a day reduced their risks of dying over the next 3.8 years by 44 percent. Newsweek, May 20, 2002
Men whose diets are wealthy in polyphenols have a remarkably reduced danger of eye blast.
Subsequent diet surveys showed that the heart-healthy Hollanders obtained some of their polyphenols from apples and onions but got a whopping 61 percentage from dark tea.
Tea contains astringent tannins. Ancient Chinese physicians valued tea’s balmy astringency for handling of diarrhoea. Today’s doctors concur, since balmy astringents are widely used to handle diarrhoea. Leading house medical guides indicate treating diarrhoea with the BRATT diet: bananas, rice, applesauce, toast and tea. Raymond Lee Geok Seng is one of the foremost experts in the health and fitness industry and is an author specializing in system health, muscle growth and dieting.
Trying to lose weight? Reach for a cup of green tea instead of a diet beverage. Compared to the placebo and caffeine, green tea extract consumption produced a significant 4% increase in 24-hour energy expenditure. If you consume 2,000 calories per day and don’t gain or lose weight (you’re in energy balance), an increase of 4% would translate roughly into an 80-calorie daily difference. Over a year, this could result in 89 pounds of weight loss. American Journal of Clinical Nutrition, Nov 1999
Recent evidence shows that in the battle of fat loss, green tea may be superior to plain caffeine. According to a new study, green tea appears to accelerate calorie burning – including fat calories. Researchers suggest compounds in green tea called flavonoids may change how the body uses a hormone called norepinephrine, which then speeds the rate calories are burned.

Tea is a better origin of fluoride, which prevents tooth decomposition. Both greenish and dark teas carry much fluoride than fluoridated water. The tannins in tea too assist defend the bacterium that induce tooth decomposition.
