According to experts it is the antioxidants in beans that give coffee a healthy and nutritional aspect. But a new study from Imperial College in London is now saying that caffeine can actually reduce the risk of brain cancer by as much as 40 percent.

Published in the Cancer, Epidemiology, Biomarkers and Prevention journal, the study said that it looked at the coffee habits of 300 patients with glioma (cancer that stars in the brain) and the caffeine habits of those without glioma.

The study revealed that those who drink 5 or more cups of coffee or tea a day had 40 percent less chance of developing brain cancer than those who do not drink coffee and tea. They said that caffeine resist blood flow to the brain, which then inhibits cancer cells from developing. Decaffeinated coffee and tea, however, don’t have the same effect.
