Ginseng, beta-carotene and
vitamins E & C reduce cancer risk for smokers.
Ginseng, together with vitamins A, C and E can
help reduce the risk of cancer caused by smoking according to researchers
at the Division of Toxicology, School of Pharmacy, SungKyunKwan
University, Suwon, South Korea.
The preventive effects of antioxidants (vitamin
E, beta-carotene, vitamin C and red ginseng) on oxidative DNA and protein
blood damage were comparatively investigated in the blood of smokers of
more than 20 cigarettes/day. Smokers showed a lower baseline level of
micronutrients (vitamin C and beta-carotene) and a higher baseline level
of oxidative DNA or protein damage than non-smokers
During daily supplementation of antioxidants (200
IU vitamin of E, 9 mg of beta-carotene, 500 mg of vitamin C, or 1.8 g of
red ginseng) for 4 weeks, the smokers antioxidant concentrations were
found to significantly increase, compared with those supplemented with a
placebo tablet.
This preliminary data suggests that
supplementation with antioxidants might protect smokers from oxidative
damages and could reduce cancer risk or other diseases caused by free
radicals associated with smoking.
