Tokyo: Scientists
say green tea and coffee, if made a regular part of the diet,
could benefit the heart, according to research conducted in Japan
and published in the US.
Green tea and coffee may help lower your risk of having a stroke,
especially when both are a regular part of your diet, according to
research published in Stroke: Journal of the American Heart
Association.
"This is the first large-scale study to examine the combined
effects of both green tea and coffee on stroke risks," said
Yoshihiro Kokubo, lead author of the study at Japan's National
Cerebral and Cardiovascular Centre.
"You may make a small but positive lifestyle change to help lower
the risk of stroke by adding daily green tea to your diet."
They found that the more green tea or coffee people drink, the
lower their stroke risks, reports Science Daily.
"The regular action of drinking tea and coffee, largely benefits
cardiovascular health because it partly keeps blood clots from
forming," Kokubo said.
Tea and coffee are the most popular drinks in the world after
water, suggesting that these results may apply in other countries
too.
It's unclear how green tea affects stroke risks. A compound group
known as catechins may provide some protection. Catechins have an
antioxidant anti-inflammatory effect, increasing plasma
antioxidant capacity and anti-thrombogenic (anti-clotting)
effects.
Some chemicals in coffee include chlorogenic acid, thus cutting
stroke risks by lowering the chances of developing type 2
diabetes.
Further research could clarify how the interaction between coffee
and green tea might help further lower stroke risks, Kokubo said.
