Tea is the most popular drink in the world and provide several health
benefits. The benefits of tea vary based on the amount of polyphenols
it contains. During the process of decaffeinating the tea, most of the
polyphenols remain intact, giving decaffeinated tea most of the benefits
that caffeinated tea has.
Green and black teas contain the most benefits and 2 to 3 cups of tea
are recommended per day for adults. Drinking decaffeinated tea is a
smart choice for those who need to avoid or limit caffeine.
Polyphenols
Polyphenols are plant compounds with antioxidant properties thought to
be more effective than vitamin C. The polyphenols in tea are known as
catechins. There are two processes used to decaffeinate tea. One that
uses ethyl acetate only retains 30 percent of the polyphenols. The
other, more natural way uses only water and carbon dioxide and retains
95 perfect of the polyphenols. Decaf tea is a smart alternative to
caffeinated tea.
Antioxidants
Antioxidants fight free radicals that can change cells, damage DNA and
cause cell death. Free radicals can lead to cancer and heart disease and
speed the aging process. Antioxidants in decaffeinated tea, especially
green tea, can help neutralize free radicals and may reduce or prevent
the damage they cause. Green and black teas provide the most
antioxidants.
Reduced Cancer Risk
Clinical studies have shown that both black and green tea protect
against cancer, according to the University of Maryland Medical Center.
Polyphenols in tea may kill cancerous cells and prevent them from
growing. Tea helps to prevent against certain cancers such as bladder,
gastric, ovarian and pancreatic cancers, according to the Mayo Clinic.
Researchers found that women under the age of 50 who drank 3 or more
cups of tea per day were 37 percent less likely to develop breast cancer
than those who did not consume tea.
Lowers Cholesterol
Tea can lower total cholesterol and raise HDL, the good cholesterol.
Polyphenols may block cholesterol from being absorbed in the intestine
and help rid the body of it. In a study of male smokers, drinking green
tea reduced blood levels of the harmful kind of cholesterol, LDL.
Drinking tea can also assist in preventing atherosclerosis, a condition
in which the artery walls thicken due to accumulation of fatty
materials, through reduction of cholesterol and triglyceride levels.
According to the University of Maryland Medical Center, the rate of
heart attack decreases 11 percent by drinking 3 cups of tea per day.
However, the U.S. Food and Drug Administration does not allow tea makers
to claim that tea reduces these risks.
