Resveratrol is found in grapes and, at least in mice, has been found to protect against lung cancer
Resveratrol, found in grapes, protects against lung cancer - health science news

Scientists have created a new formula for the application of resveratrol to protect against lung cancer. Resveratrol, which is found in grapes and red wine, was found to be most effective when applied intranasally in mice that had been exposed to a carcinogenic substance from cigarette smoke. The amount of resveratrol that reached the lungs was 22 times higher when compared with oral intake that is without effect. As resveratrol is already used in food supplements, no further toxicity studies are needed prior to commercialization as a preventive treatment of lung cancer.
