Coffee, exercise may fight cancer
Tuesday, July 31, 2007
DRINKING coffee and exercising may prevent skin cancer by killing off cells damaged by the sun's ultraviolet-B (UVB) radiation, said a study of hairless laboratory mice published yesterday.
The coffee-exercise combination produced a "dramatic" fourfold difference in apoptosis the programmed death of pre-cancerous cells between laboratory mice that did and did not follow the regime, said the researchers of New Jersey's Rutgers University.
Researchers compared UVB radiation effects on groups of hairless mice that drank caffeinated water (the human equivalent of one or two cups of coffee a day); that exercised on a running wheel; that had caffeine and ran; and a control group that had no caffeine or exercise at all.
Compared to the control group, mice that only drank coffee showed a 95 per cent increase in UVB-induced apoptosis, those that only exercised showed a 120 per cent increase, while those who drank and exercised showed an almost 400 per cent increase.
The study is published in the Proceedings of the National Academy of Sciences.
