Despite recent adverse publicity, beta-carotene does provide an effective safeguard against lung cancer, new research has found.

People with high levels of beta-carotene had the lowest lung cancer rates, even though they were in a high risk group, either as a smoker or as an asbestos worker.

But smokers were warned that they first have to quit if the supplementation is to have any effect. In fact, beta-carotene can have harmful effects on people still smoking, and also among heavy drinkers (J Natl Cancer Inst, 1996; 8: 1560-70).
