THURSDAY, Oct. 28 (HealthDay News) -- Coffee and tea consumption is associated with a lower risk of glioma, according to research published in the November issue of the American Journal of Clinical Nutrition.
Dominique S. Michaud, of Imperial College London, and colleagues analyzed data from 410,309 men and women in the European Prospective Investigation into Cancer and Nutrition study, who reported coffee and tea consumption in food-frequency questionnaires and were followed for a mean 8.5 years.
The researchers found that, during this time, 343 glioma and 245 meningioma cases were diagnosed. Individuals consuming at least 100 mL of coffee and tea daily were found to have a lower risk of glioma compared to those drinking less (hazard ratio, 0.66). These cutoffs for coffee and tea consumption combined weren't found to be associated with meningioma risk, nor was a 200-mL daily cutoff.
"Coffee and tea both contain caffeine and many other compounds, some of which have antioxidant properties. In fact, coffee has a greater total antioxidant capacity (i.e., cumulative capacity of food components to scavenge free radicals) than any given fruit or vegetable. Given that we did not observe an association between coffee and tea consumption and meningioma risk, it is possible that the effect of coffee, if causal, is acting late in the process of carcinogenesis by preventing tumor growth," the authors write.
