Good Diet and Gardening Linked To Lower Lung Cancer Risk

'By simply eating four or more servings of green salad a week and working in the garden once or twice a week, smokers and nonsmokers alike may be able to substantially reduce the risk of developing lung cancer, say researchers at The University of Texas M. D. Anderson Cancer Center.'

Fruits, Vegetables And Teas May Protect Smokers From Lung Cancer, Researchers Report

'Tobacco smokers who eat three servings of fruits and vegetables per day and drink green or black tea may be protecting themselves from lung cancer, according to a first-of-its-kind study by UCLA cancer researchers.

UCLA researchers found that smokers who ingested high levels of natural chemicals called flavonoids in their diet had a lower risk of developing lung cancer, an important finding since more than 90 percent of lung cancers are caused by tobacco smoking.'

Green tea reduces lung cancer risk

Experts believe it is the polyphenols in green tea that may make it beneficial

"Lung cancer is the leading cause of all cancer deaths in Taiwan," said I-Hsin Lin, a student at Chung Shan Medical University, Taiwan, who conducted the study.

"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 tumorigenesis (production of new tumour)," added Lin.

Lin and colleagues enrolled 170 patients with lung cancer and 340 healthy patients as controls.

They administered questionnaires to obtain demographic characteristics, cigarette smoking habits, green tea consumption, dietary intake of fruits and vegetables, cooking practices and family history of lung cancer.

Among 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.

Lin and colleagues suspect genetics may play a role in this risk differential, says a release of the American Association for Cancer Research.

"Our study may represent a clue that in the case of lung cancer, smoking-induced carcinogenesis could be modulated by green tea consumption and the growth factor environment," said Lin.

The study was presented at the AACR-IASLC Joint Conference on Molecular Origins of Lung Cancer, being held Jan 11-14.
