Your Morning Brew May Reduce Brain Tumor Risk
Like a cup of coffee or tea during the day? You'll be happy to learn that drinking about 1/2 a cup of either coffee or tea each day may significantly reduce the risk of certain brain tumors, according to new research published in the November 2010 issue of the American Journal of Clinical Nutrition.
This study was conducted as part of the European Prospective Investigation into Cancer and Nutrition (EPIC) longitudinal study. The EPIC study followed more than 400,000 individuals from 9 nations for over 8 years. Study participants completed diet, lifestyle and food frequency questionnaires. Cancer diagnosis was based on national cancer registries and health insurance records.
Researchers examined the relationship between coffee and tea intake and the risk of glioma (tumors of the brain or spinal cord) and meningioma (tumors of the tissue surrounding the brain and spinal cord).
During the course of the study, 343 cases of glioma and 245 cases of meningioma were newly diagnosed. They found that those consuming more than ½ cup of coffee and/or tea per day had a 34% lower risk of developing glioma than those consuming less than ½ cup per day. This effect was stronger in men than women.
They did not find any correlation with consumption and meningioma risk.
The researchers concluded that their data suggests an association between coffee/tea consumption and risk of glioma. They recognize that additional prospective studies need to be undertaken to confirm their findings. Additional experimental studies will need to be conducted to determine whether altering coffee and/or tea consumption necessarily affects brain tumor risk.
