In an amazing study, both tea and coffee have been associated with a sharply lowered risk of glioma, a cancer that originates in the brain and spinal column. The association wasn’t small — just 0.4 cups of coffee a day was associated with a 34% reduction in gliomas.
The authors presented no mechanism for what role coffee and tea may play in the brain cancer reduction so at the moment it is unclear how the beverages work their magic or even if lifestyle differences between coffee/tea drinkers and non-drinkers may be the reason. However, the association is strong enough that researchers from several prestigious institutions were full of praise for the study.
Dr. John S. Yu from the Brain Tumor Center of Excellence at Cedars-Sinai Medical Center in Los Angeles was quoted in USA Today as saying, “If we had a drug for any disease that could demonstrate a risk reduction of 34%, that would be considered a great drug. That degree of risk reduction is very strong.”
The study was also very large — 410,000 men and women were followed for 8.5 years, leading to more certainty about the study’s conclusions.
Very fascinating stuff… I wonder if one day these beverages will get a special compartment in the food pyramid taught to school children?
The study was published in the American Journal of Clinical Nutrition which has generously granted access to the full article via it’s website at the following link: Coffee and tea intake and risk of brain tumors in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort study.
