U.S. researchers found lycopene and grape seed extract drastically reduced the amount of cancer-causing free radicals produced in cigarettes. Study co-author Dr. Boris Dzilkovski and Kolski-Andreaco at Cornell University in Ithaca, N.Y., said from a healthcare perspective, the best cigarette is no cigarette, but a less toxic cigarette may be helpful for the millions of people a year who try to quit smoking. \"The implications of this technique can help reduce the hazardous effects of tobacco smoke because free radicals are a major group of carcinogens,\" Dzilkovski said. Using the natural antioxidant extracts -- lycopene, the bright red pigment and phytochemical found in tomatoes and other red fruits and vegetable and grape seed extract -- in cigarette filters, drastically reduced the amount of cancer-causing free radicals passing through the filter. \"Practically, this research could lead to an alternative type of cigarette filter with a free radical scavenging additive,\" Kolski-Andreaco said. \"It could lead to a less harmful cigarette.\" The findings were published in the Journal of Visualized Experiments, a video journal.
