Saturday Dec 15, 2012 (foodconsumer.org) -- A study in Nutrition and Cancer suggests that consumption of fruit, eggs and tea may help prevent lung cancer, a malignancy that kills more than 170,000 American men and women each year while passive smoking seems to increase the risk of developing lung cancer.

Y. Lin and L. Cai from School of Public Health, Fujian Medical University, Fujian Province, People's Republic China conducted the study and found the inverse association between intake of fruit, eggs and tea, and risk of lung cancer.

This case-control study involved 226 female lung cancer cases and 269 controls, residents in Fujian Province, who were enrolled in the study between 2006 and 2010. Information on dietary and environmental exposure was obtained through a questionnaire.
 
In addition to the dietary factors, exposure to cooking oil fumes (the Chinese use high heat to cook, which generates cooking oil fumes often) and passive smoking were associated with elevated risk of lung cancer.

Frequent physical activity and late age at menarche were correlated with lower risk of lung cancer in women.  Late age at menarche has been associated with lower risk of breast cancer in previous studies.

The researchers concluded "The results demonstrate that some environmental and dietary factors are related to the risk of lung cancer among the female population in southeast China."
