小题1:________________
Americans are far more knowledgeable about drinks than they were 20 years ago. Witness the Starbucks revolution and you’ll know where the trend goes. Now, encouraged by recent studies suggesting that it can cut the risk of cancer and heart disease and slow the aging process, tea is enjoying a similar change. Enough fashionable tea houses are springing up to make even longtime coffee drinkers consider switching drinks.
小题2:________________
Tea is available in more places than ever. The Tea Association of the United States reports that from 1990 to 1999, annual sales of the drink grew to $4.6 billion from $1.8 billion. “Green tea is seen by consumers as a ‘functional food’” — delivering health benefits beyond food itself, says Vierhile.
小题3:_______________
Recently published studies point out that only teas that come from the leaves of the plant Camellia sinensis have been shown to contain health benefits. Other herbal teas may taste good, yet they do little more than warm up the drinker. But for Camellia sinensis, the evidence is powerful. In a 1998 study, Harvard University researchers found that drinking one cup of black tea a day lowered the risk of heart attack by as much as 44 percent compared with non-tea drinkers, and other studies have suggested that the antioxidants (抗氧化剂) in these so-called real teas can also prevent cancer.
小题4:________________
One such antioxidant in green tea is ECGC, a compound 20 times as powerful as vitamin E and 200 times as powerful as vitamin C. “When people ask me for something good and cheap they can do to reduce their cancer risk, I tell them to drink real tea,” says Mitchell Gaynor, director of medical oncology at New York City’s Strang-Cornell Cancer Prevention Center.
小题5:________________
Among those inspired to become a green-tea drinker is Tess Ghilaga, a New York writer who took it up after seeking advice from a nutritionist six years ago. “I’ve never been a coffee drinker,” says Ghilaga, 33. “She told me to start drinking green tea for the antioxidant qualities.” Now Ghilaga and her husband habitually make tea — they order theirs from InPursuitofTea.com, an Internet tea company. And although tea contains about half the amount of caffeine in a cup of coffee, “you still get such a kick from it,” says Ghilaga.
