Drinking Tea May Guard
Against Ovarian Cancer
by Nicole Weaver
Consuming two or more cups of
tea a day over a period of time may reduce the risk of ovarian
cancer dramatically, suggests a new study published in the
Archives of Internal Medicine. And each additional cup of tea per day appears to
provide significantly more protection, investigators
found.
Because tea is the second most-consumed beverage in the world,
its potential health benefits could have important implications
for human health and disease prevention, says the Tea Council
of the USA.
"An abundance of research suggests that tea may play a role in
the reduction of risk of cardiovascular disease and various
types of cancer," notes Joe Simrany, president of the trade
organization. "These new findings suggest that drinking tea
regularly may help to reduce the risk of ovarian cancer as
well. This is good news and points to yet another area where
tea may have a positive effect on health."
46 Percent Lower Ovarian Cancer Risk
Researchers at Sweden's National Institute of Environmental
Medicine, Karolinska Institutet, examined the association
between tea consumption and risk of ovarian cancer in 61,057
women 40 to 76 years of age who took part in the
population-based Swedish Mammography Cohort.
The participants completed a validated 67-item food frequency
questionnaire at enrollment between 1987 and 1990, and were
followed for cancer incidence through December 2004.
At baseline, 68 percent of the participants reported drinking
tea -- primarily black tea -- at least once a month. During
15.1 years of follow-up, 301 women were diagnosed as having
epithelial ovarian cancer. The researchers found tea
consumption of two or more cups of tea per day had a
significant inverse association with risk of ovarian
cancer.
Specifically, women who drank two or more cups of tea per day
experienced a 46 percent lower risk of ovarian cancer, compared
with women who drank no tea. Each additional cup of tea was
associated with an 18 percent decreased risk of ovarian
cancer.
Additional Health Benefits
A multitude of research studies suggest that drinking tea may
contribute to overall health. Potential benefits include the
following:
- Reduced risk of heart attack and stroke, and improved blood
vessel function;
- Less risk of certain cancers, including colorectal and skin
cancers;
- Decreased levels of oxidative DNA damage and increases in
antioxidant levels in the bloodstream; and
- Oral health benefits -- researchers believe certain compounds
in tea may inhibit bacteria that cause bad breath and plaque,
and the fluoride content in tea supports healthy tooth
enamel.
