Beta carotene may protect against the cancer causing effects of cigarette smoke

Dietary beta carotene may protect against prostate cancer in men who smoke, according to a recent report from the University of Buffalo.

Researchers gathered information about dietary and smoking habits from 415 men with prostate cancer and 524 men without prostate cancer. Analysis of the information showed that light smokers were two thirds less likely to develop prostate cancer if their diets included medium to high levels of beta carotene. Heavy smokers appeared to reduce their risk by 50 per cent if their diets included high levels of beta carotene. The results also suggested that beta carotene had not effect on those who did not smoke.
