Researchers have been reporting benefits from green tea for years. Some studies note a lower risk of cancer among those who drink several cups daily. Now a study from Taiwan suggests that drinking at least one cup of green tea daily may help smokers reduce their risk of developing lung cancer. In this study, subjects who were not genetically prone to lung cancer got the greatest benefit. They lowered their likelihood of lung cancer by 66 percent. Of course, drinking green tea is no substitute for smoking cessation. But it may be useful for smokers who are trying to quit and lower their risks.
