     A few cups of green tea each day may help prevent heart disease,Greek researchers said

on Wednesday.A study published in the European Journal of Cardiovascular (心血管的)

Prevention showed further evidence of the potential health benefits from tea already linked

to a reduced risk of a range of cancers and other conditions.

     The study showed that green tea improves blood flow and the ability of arteries (动脉)

to relax,said Charalambos Vlachopoulos,an expert at the Athens Medical School in Greece

who worked on the study.

     Other studies have shown that black tea also has benefits for cardiovascular health.

     The Greek team said they believed green tea might be even better because it had higher

quantities of beneficial substances called flavonoids (类黄酮)-some of which are lost in the

oxidation (氧化) process that black tea undergoes.

     Flavonoids are also found in cocoa,tomatoes and grapes."A couple of cups a day would

probably be good for people," Vlachopoulos said."This is the first study to show these

effects for green tea."

     The researchers gave 14 healthy volunteers either green tea,coffee or hot water and then

measured the function of endothelial cells (内皮细胞)．These cells help relax arteries and

ease blood flow."What is important is these effects are evident within 30 minutes,"

Vlachopoulos said.

     The measurements taken 30,90 and 120 minutes following consumption showed an

almost immediate benefit among people who had drunk green tea,he said.While the researchers

looked only at a short-term effect,Vlachopoulos said the team's studies suggest the protection

is long-lasting.

     "Green tea is consumed less in the Western world than black tea,but it could be more

beneficial,"he said.
