WEDNESDAY, Oct. 20 (HealthDay News) -- Researchers have discovered that coffee and tea might do more than boost your energy levels: Regular consumption of the world's two most popular beverages may also shield you against a form of brain cancer.
In fact, the latest research suggests that those who drink as little as a half cup or so of coffee per day may lower brain cancer risk by as much as 34 percent.
Lead researcher Dominique S. Michaud, of Brown University's department of community health in Providence, heads an international team that reports the finding in the November issue of the American Journal of Clinical Nutrition.
The notion that coffee and tea might accrue an anti-cancer health benefit to regular drinkers builds on previous research that has indicated that the beverages may also lower the risk for both Alzheimer's and Parkinson's disease.
The current effort explored the possibility that coffee and tea may also protect against brain cancer, specifically in the form of glioma, a cancer of the central nervous system that originates in the brain and/or spinal cord.
Data concerning the dietary habits of more than 410,000 men and women between the ages of 25 and 70 was drawn from the European Prospective Investigation into Cancer and Nutrition study, which included participants from France, the Netherlands, Italy, Spain, Great Britain, Greece, Denmark, Norway, Sweden and Germany.
Participants were recruited between 1991 and 2000, and were tracked over the course of about 8.5 years. During that time, food surveys were completed to gauge, among other things, the amount of tea and coffee each participant consumed.
During the study, 343 new cases of glioma were diagnosed, as were 245 new cases of meningioma, another cancer that affects tissue surrounding the brain and spinal cord.
