Drinking at least a cup of green tea a day may significantly decrease a person's risk of lung cancer, according to a study conducted by researchers from Shan Medical University in Taiwan. Laboratory studies have suggested that the polyphenols in green tea can halt the growth of cancer cells.
Scientists do know that green tea contains chemicals that are anti-oxidants and quench harmful molecules. In the current study, researchers analyzed green tea consumption, smoking, genetic factors and lung cancer risk in more than 500 people.
They found that among non-smokers, those who did not drink tea had five times the lung cancer risk of those who drank at least one cup per day. Among smokers, not drinking green tea was linked to 12 times the cancer risk of those who drank at least one cup per day.
“Tea, particularly green tea, has received a great deal of attention because tea polyphenols are strong antioxidants, and tea preparations have shown inhibitory activity against tumor genesis.
