Coffee and tea may be more than one way to raise energy levels. Regular consumption of the two most popular drinks in the world could also protect against a form of brain cancer. Those who drink only half a cup of coffee a day may reduce the risk of brain cancer by up to 34%, and may also reduce the risk of both Alzheimer’s and Parkinson’s. Research director Dominique S. Michaud from the health department at Brown University in Providence says that coffee and tea may also protect against brain cancer, specifically against the glioma, a cancer of the central nervous system that originates in the brain and spinal cord.” During the study researchers extracted data on the dietary habits of over 410 thousand men and women between 25 and 70 years old, from the European Prospective Investigation into Cancer and Nutrition. The study involved participants from France, the Netherlands, Italy, Spain, Great Britain, Greece, Denmark, Norway, Sweden and Germany. Participants were recruited between 1991 and 2000 and they were followed for about eight years. In this period, dietary survey completed to measure, among other things, the amount of tea and coffee consumed by each participant. Doctors diagnosed 343 cases of glioma, as well as 245 new cases of meningioma, another cancer that affects the tissue surrounding the brain and spinal cord. It was found that decaffeinated coffee consumption was very low in general, while the consumption patterns of coffee and tea varied greatly from country to country. For example, while the Danes (the largest consumers of coffee) drank on average about 3.5 cups a day, the Italians (the least consumed) averaged less than half a cup a day. Tea consumption was higher in Britain, and lowest in Spain. By comparing the patterns of consumption against the incidence of brain cancer, the team found that drinking 100 ml per day reduced the risk of gliomas in 34%. The protective effect appears to be slightly higher in men, and seems to apply exclusively to gliomas.
