Coffee and tea are widely enjoyed throughout the world, both of which were the subject of numerous health claims (most of them are unproven). Tea, green tea, and in particular, the focus of extensive research, with many prior studies suggest that tea can improve cardiovascular health and, to a lesser extent, may reduce the risk of some cancers. Much of the published research about coffee, on the other hand, has focused on trying to refute the alleged link between coffee consumption and can increase the risk of some cancers. (Fortunately, the vast majority of such research has not identified a strong link between moderate coffee consumption and increased risk of cancer .)

The European Prospective Investigation into Cancer and Nutrition (EPIC) study is an ongoing large prospective multinational public health studies, and some of this huge study preliminary results already objavljeni.EPIC study focused on potential links between diet, nutritional status, the way life and environmental factors and the incidence of cancer (among other chronic diseases). (EPIC is one of the largest study of diet and health ever undertaken, a study has recruited 520,000 volunteers in Denmark, France, Germany, Greece, Italy, Netherlands, Norway, Spain, Sweden and the UK.) Now, a new update of this historic public Health studies show that increased consumption of coffee and tea may be associated with reduced incidence of malignant brain tumors. This new update from the EPIC study, which was published in the current issue of American Journal of Clinical Nutrition.

The average duration of follow-up of almost 9 years, 588 new cases of brain tumors were diagnosed among the EPIC study volunteers. Gliomas, the most common and most aggressive type of brain tumor that occurs in adults, it was found that 34 percent less common in people who drank at least 100 milliliters (3.4 ounces) of coffee or tea a day. (Although not statistically significant, this association was also noted that the stronger in men, with a 41 percent lower risk of gliomas in males, compared to 26 percent reduction in the incidence of glioma in women .)

Although it is not clear what causes gliomas of the brain, before public health studies at least have suggested a link between glioma brain tumors and chronic occupational exposure to high intensity electric and magnetic fields, and rubber and plastics manufacturing. (As I discuss in the "Cancer Prevention Guide for the human race, there is some data linking long-term use of mobile phones with an increased incidence of gliomas and other brain tumors .)

Other smaller public health studies have also identified a clear link between increased caffeine intake and reduced incidence of gliomas, and there is laboratory evidence available suggests that caffeine may reduce the growth of malignant glioma cells growing in culture dishes. Thus, these new results from the EPIC study diva further suggest the possibility that coffee, tea and other caffeinated beverages can help reduce the risk of gliomas of the brain.
