Two separate studies found that green tea and a diet rich in green vegetables may prevent lung cancer.

The first study compared smokers who consumed one cup of green tea or more per day against smokers who did not regularly drink the hot beverage. According to a Los Angeles Times article, researchers found that those "who did not drink green tea were 12.7 times more likely to develop lung cancer."

The second study focused on current and former smokers who took multivitamins and ate a diet rich in leafy-green vegetables and folic acid. According to the study, which was published this week in Cancer Research, it was discovered that the diet protected against "promoter methylation", which is associated with developing lung cancer.

Other researchers suggest more studies should be conducted before doctors recommend these dietary changes for lung cancer prevention.
