Green tea reduces carcinogenic effect of smoking
Drinking green tea could reduce the effect of smoking on lung cancer. Researchers in Taiwan enrolled 170 patients with lung cancer and 340 healthy controls in their study. Among both smokers and non-smokers, those who did not drink green tea had a 5.16-fold increased risk of lung cancer, compared with those who drank at least one cup of green tea per day.
Among smokers, those who did not drink green tea at all had a 12.71-fold increased risk of lung cancer compared with those who drank at least one cup of green tea per day.
