A higher tea and coffee consumption appears to be associated with a reduced risk of glioma

In February 2019 researchers from Iran published the results of their study to assess the association between tea and coffee consumption and risk of glioma in Iranian adults. A total of 128 individuals, newly diagnosed with glioma, and 256 age- and sex-matched controls were involved in the study. Information on dietary intake, including tea and coffee consumption, was collected via a 123-item food frequency questionnaire. The individuals were then divided into groups based on their tea and coffee consumption. Results showed that those individuals with the greatest tea or coffee consumption were less likely to have glioma when compared to those with the lowest consumption. In fact those individuals in the top group of coffee consumption appeared to be 91% less likely to have glioma compared with those in the bottom group.
