Aging
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 Straits Times, Sept. 24, 01
Allergies
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
Arthritis
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
Green tea may be useful in controlling inflammation from injury or diseases such as arthritis. Boston Globe, April 26, 99
Bone Strength
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. U.S. News & World Report, May 20,

Cancer
"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
Cholesterol
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.

Heart Disease
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,Ó 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.

Weight Loss
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. Joe Weider's Muscle & Fitness, April 2000
