Coffee, exercise may fight cancer
WASHINGTON
31-Jul-07
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.
